    [0001] [001] A plastic tube forming apparatus is revealed. Also disclosed is a method of relocating and assembling a tube forming apparatus, and a system for producing plastic tubes. The device can be modularized and transported, and finds specific application for use in the manufacture of plastic pipes on site, or in close proximity to the pipe laying site. However, it must be recognized that the device has a wider application, and is not limited to that use. Background art
    [0002] [002] Plastic pipe has a variety of industrial uses, including water supply, waste water and sewage, gas and liquid transportation, as well as a protective barrier for electrical and telecommunication cables. Plastic pipes are particularly useful as they are corrosion resistant, flexible and offer weight advantages compared to alternative pipe construction materials such as copper, cast iron and other metals. These qualities provide significant cost savings, and plastic tubes have been used extensively in the water, agriculture, mining, construction, infrastructure, energy, electrical and telecommunications sectors.
    [0003] [003] Plastic tubes are manufactured by tube extrusion within a factory, thereby allowing production in a controlled environment. The extrusion of plastic tube generally involves feeding plastic raw material through a hopper into the cylinder of the extruder. Inside the cylinder, a rotating screw rotates and advances the plastic supply, with the assistance of heaters, to fuse and pressurize the plastic supply in molten plastic. The pressurized molten plastic is then forced through a matrix having an annular profile, thereby producing an extruded tube. The newly extruded tube is then passed through a series of cooling tanks, which spray water to solidify the plastic tube. The tubes can then be wound up for storage and / or transportation before laying the tubes.
    [0004] [004] With tubes of larger diameter, there can be substantial difficulty in winding the tube in a coil that can be transported over long distances. For example, the tube can be manufactured from a factory in an industrial area that needs to be transported by conventional means such as by ship, road and rail. These modes of transport have physical limitations in size and volume of cargo, so large diameter tubes are usually manufactured in sections of controllable size and weight, typically 20 meters long. These sections are transported to the pipe laying site, where multiple sections are joined by a coupling, which may involve plastic welding of the ends of the pipe sections. Such coupling of the pipe sections is time-consuming and adds additional costs to labor and materials. Summary of revelation
    [0005] [005] In a first aspect, a modular plastic tube forming apparatus is disclosed, the apparatus comprising a plurality of modules where each module comprises at least one component of the tube forming apparatus located therein, wherein the plurality of modules are aligned in a predetermined manner during the formation of the plastic tube.
    [0006] [006] By modularizing at least part of the tube forming apparatus, tube manufacturing can take place on site (At least, for space-intensive, bulky stages). This can save on shipping and cost, as outlined in detail below.
    [0007] [007] In one form, one of the plurality of modules comprises a plastic extruder. One of the plurality of modules comprising the plastic extruder and can further comprise a plastic raw material dryer and a die head.
    [0008] [008] In one form, one of the plurality of modules comprising the plastic extruder further comprises a pipe corrugator for corrugating pipe extruded from the die head.
    [0009] [009] In an alternative form, the plastic tube forming apparatus further comprises a corrugator module for positioning adjacent to one of the plurality of modules comprising the plastic extruder for receiving from it and corrugating extruded tube. A separate corrugator module allows the operator to selectively configure the machine to produce corrugated or straight-walled tubes by simply inserting or removing the corrugator module from the plastic tube forming apparatus.
    [0010] [010] In one form of the modular plastic tube forming apparatus, at least one of the other components comprises a cooling tank. In an additional form, two or more cooling tank modules are supplied in series to receive extruded plastic tubes in them for cooling. The cooling tank cools the hot extruded plastic tube in a solid state. Typically, the cooling tank contains a spray of water to cool the plastic.
    [0011] [011] Still in an additional form, a first of the two or more cooling modules comprises a vacuum water tank. The vacuum helps to extrude the molten plastic tube from the die head.
    [0012] [012] In an additional form, the modular plastic tube forming apparatus further comprises one or more modules comprising one or more of the following components: a pull-out Caterpillar, a cutter, a tube sliding table , a tilting table and a winding means.
    [0013] [013] In one form, the plurality of modules is aligned in a predetermined way during plastic tube formation.
    [0014] [014] In another form, a module or each module of the plastic tube forming apparatus is adapted to be transportable.
    [0015] [015] In a form of the modular plastic tube forming apparatus, the plurality of modules are adapted to be coupled together in use, and decoupled from each other during transport of the apparatus.
    [0016] [016] In a form of the modular plastic tube forming apparatus, at least one of the modules comprises a standardized shipping container, optionally modified for use in the apparatus. In an alternative form, at least one of the modules comprises a container or support structure for use in the apparatus and having at least some of the characteristics of a standardized shipping container to facilitate its transport. By providing modules having the characteristics of standard shipping containers, it allows modules to be handled and transported using existing vehicles and infrastructure. This keeps transport costs for the device to a minimum.
    [0017] [017] In a form of the modular plastic tube forming apparatus, the adjacent modules are adapted to be locked together during tube forming. Locking the modules together ensures that the modules are in their desired predetermined arrangement. In this way, the operator can be confident that the modules are correctly arranged, and will not deviate in position.
    [0018] [018] In one form, the modular plastic tube forming apparatus further comprises an adjustment mechanism for closely positioning adjacent modules before locking them together. This mechanism can take the form of a winch, with a winch base attached to one module, and the end of a winch cable attached to another module, the operation of the winch pulling the modules together. This allows the modules to be initially positioned in an arrangement approximately arranged by a crane. Subsequently, the adjustment mechanism allows the modules to be closely positioned and aligned with each other. This avoids the use of cranes to position modules in precise locations, which can be difficult since the modules can be the size of shipping containers, which are bulky and cumbersome to lift and position.
    [0019] [019] In one form, the modular plastic tube forming apparatus also comprises external supports to support respective modules. The external supports may comprise adjustable jacks to adjust the position or angle of the supported module. In another form, the external supports also comprise piles for attachment to the underlying soil. The external supports allow the modules to be placed and used on softer or uneven ground, as well as providing soil clearance for water drainage.
    [0020] [020] In a shape, the position or angle of a component in a module is adjustable with respect to its module. In an additional form, the plurality of components arranged in the modules is adjustable in position or angle, allowing the plurality of components to be aligned for tube formation. This allows the components of the tube forming apparatus to be aligned even if the support modules are not perfectly aligned. This can be advantageous where the production site is not perfectly level, or if the modules have not been precisely arranged.
    [0021] [021] In one form, the device also comprises a reference laser beam to assist in the alignment of components and / or modules.
    [0022] - uma pluralidade de módulos com cada módulo compreendendo pelo menos um componente do sistema de formação de tubo; e - um mecanismo de alinhamento para alinhar um componente em um módulo com um componente em outro módulo. [022] In a second aspect, a tube forming system is revealed comprising: - a plurality of modules with each module comprising at least one component of the tube forming system; and - an alignment mechanism for aligning a component in one module with a component in another module.
    [0023] [023] In one form of the system, the modules are configurable as transportable containers, the manufacturing system further comprising a conveyor to transport the modules to and from a pipe production site, with the transportable containers and conveyor together providing a mobile tube manufacturing system. The carrier can be in the form of a rail wagon semitrailer or a ship container.
    [0024] [024] In one form, at least one component of the system is a plastic extruder.
    [0025] [025] In one form, the tube forming system further comprises a winding means optionally disposed with respect to a module.
    [0026] [026] In one form, the tube forming system further comprises tube trailers for transporting tube to the tube settlement site.
    [0027] [027] In one form, the tube forming system further comprises a power generation unit optionally arranged with respect to a module.
    [0028] [028] In one form, the tube forming system further comprises a cooling unit to provide a closed circuit cooling water supply for a cooling tank component, the cooling unit and / or optionally arranged cooling tank with respect to a module.
    [0029] [029] With the power generation unit and the cooling unit as a transportable and modular part of the tube forming system, the tube forming system can be self-sufficient, without relying on existing infrastructure as a power and plumbing network at the production site. This allows the system to be employed at a production site in a remote location.
    [0030] [030] In one form, hot air can be extracted from the inside of the newly extruded tube, or from other locations in the tube forming apparatus or system. This hot air can be recycled to the raw material dryer for use in drying the raw material. This can reduce the power requirements of the system.
    [0031] - dispor dois ou mais módulos respectivos em relação mútua; e - dispor dois ou mais componentes respectivos do aparelho de formação de tubo em relação mútua. [031] In another aspect, a method for forming plastic tube employing a form of the apparatus of the first aspect is disclosed. The method comprises: - have two or more respective modules in mutual relationship; and - arrange two or more respective components of the tube forming apparatus in mutual relation.
    [0032] [032] In an additional form, the method further comprises forming plastic tube.
    [0033] - dispor a pluralidade de módulos em um modo predeterminado em um local de produção; - dispor dois ou mais componentes respectivos do aparelho de formação de tubo; - fornecer o aparelho de formação de tubo de plástico com matéria prima de plástico cru; - acoplar os módulos juntos; e - alinhar os componentes do aparelho de formação plástico para permitir a formação de tubos. [033] In another aspect, a method of forming plastic tube is disclosed, using a modular plastic tube forming apparatus comprising a plurality of modules supported by components of the tube forming apparatus, the method comprising: - arrange the plurality of modules in a predetermined mode at a production site; - have two or more respective components of the tube forming apparatus; - supply the plastic tube forming apparatus with raw plastic raw material; - couple the modules together; and - align the components of the plastic forming apparatus to allow the formation of tubes.
    [0034] [034] In an additional form, the coupling of the modules and arrangement of the components comprises: - lock the modules together.
    [0035] [035] In one form of the method, the components are aligned using a laser to determine the position of the components and then, as necessary, adjust the alignment of the components.
    [0036] - transportar os módulos para o local; - dispor os módulos em um modo predeterminado no local; - acoplar os módulos juntos; - alinhar os componentes do aparelho de formação plástica para permitir a formação de tubos; - fornecer matérias primas, energia e água ao aparelho de formação de tubo de plástico; e - formar tubo de plástico. [036] In another aspect, a method of establishing a mobile plastic pipe manufacturing site is revealed. The location that is adapted to locate a modular plastic tube forming apparatus comprising a plurality of modules supporting components of the tube forming apparatus. The method comprises: - transport the modules to the site; - arrange the modules in a predetermined mode on site; - couple the modules together; - align the components of the plastic forming apparatus to allow the formation of tubes; - supply raw materials, energy and water to the plastic tube forming apparatus; and - form a plastic tube.
    [0037] [037] In a form of the method, coupling the modules together comprises locking the modules together.
    [0038] [038] In one form of the method, the modules and components are initially configured in a transportable state, with the method further comprising configuring the components and modules in a production state after the step of transporting the modules to the production site.
    [0039] - desacoplar os módulos; - configurar os componentes e módulos em um estado transportável; - transportar os módulos a partir do local de produção até o segundo local de produção; - posicionar os módulos em um modo predeterminado; - acoplar os módulos juntos; - fornecer matérias primas, energia e água ao aparelho de formação de tubo de plástico; e - fabricar tubo de plástico. [039] In a form of the method, after plastic tube manufacturing at the production site has ceased, the modular plastic tube forming apparatus can be relocated and assembled at a second production site, with the method then comprising: - decouple the modules; - configure the components and modules in a transportable state; - transport the modules from the production site to the second production site; - position the modules in a predetermined mode; - couple the modules together; - supply raw materials, energy and water to the plastic tube forming apparatus; and - manufacture plastic tube.
    [0040] [040] The apparatus, system and methods revealed here allow pipe production in remote locations, so the pipe formation can be carried out in close proximity to the location where the pipe will be used. This reduces transportation of the finished product, which can be considerably expensive for transportation over long distances. In this way, effective transport costs are reduced since the finished product may not even need to travel from the point of manufacture to the location. This also considerably reduces the timeline from when the pipe is manufactured to when it is delivered, so installation time is also reduced.
    [0041] [041] Furthermore, since the manufactured pipe only needs to move a relatively short distance between fabrication and laying of the pipe, the length of the pipe produced can be increased. Transporting large sections can be achieved by using specialized tube trailers to move tubes from the production site to the tube settlement site. Manufacturing can take place even adjacent to where the pipe is to be laid.
    [0042] [042] By producing longer lengths of pipe the number of welds and couplings between pipe sections can be reduced, leading to less material, labor and overall costs for the pipe. In addition, a smaller number of welds and couplings leads to less chance of defects in the couplings and less chance of compromising the integrity of the piping.
    [0043] [043] In addition, longer sections of pipe and shorter transport distances reduce overall pipe handling, and reduce the possibility of freight damage from the pipe in transit. In addition, shorter transport distances improve public safety as bulky tubes do not need to travel long distances on public roads.
    [0044] [044] A mobile tube manufacturing facility also allows for the supply of tube that may otherwise be logistically difficult to deliver. For factory-produced tubes, there was a reliance on transport capable of transporting manufactured tube between the factory and the tube site. In remote locations, traditional transportation methods may not be able to transport bulky pipe across uneven or remote terrain. By providing a mobile tube manufacturing facility, the tube extrusion machine itself can be separated into modules in the form of containers, controllable. These modules can then be more easily transported to a remote location, and assembled to manufacture pipes on site.
    [0045] [045] In addition, in this system, by providing the piping customer with the means to produce pipes in close proximity to the site, it allows additional flexibility for the customer to easily and quickly change pipe specifications, and to increase or decrease pipe production. This flexibility improves delivery times and simplifies on-site handling and storage costs. Brief description of the drawings

Detailed Description
    [0047] [047] Figure 1 illustrates a plan view of a modular plastic tube forming apparatus 1 configured for smooth wall tube production. The tube forming apparatus 1 comprises a series of modules 3, each comprising modified transport containers, in which components of the tube forming apparatus are arranged. Modules 3 are coupled together in a predetermined layout, allowing the components in it to be aligned for tube production.
    [0048] [048] In the first module 5, a raw material dryer 7, screw extruder 9 and a die head 11 are provided. In the second module 15, a vacuum water tank 17 is provided. The third and fourth modules 19 house water cooling tanks 21. The fifth module 23 houses a pull-out Caterpillar, and the sixth module 27 houses a cutter 29.
    [0049] [049] Other components for tube production may include a raw material feed and storage component 31, a power generation unit 33, a cooling unit 35, tube sliding table / tilting table 37 and a means of tube winding 39.
    [0050] [050] In the production of tubes, energy and water are supplied to the first module 5 from the power generation unit 33 and cooling unit 35. Plastic raw material is fed from the raw material supply and storage component 31 for the raw material dryer 7, where the plastic raw material is dried before feeding into the screw extruder hopper 9. The plastic raw material is then heated and pressurized in the screw extruder 9 cylinder, thereby creating a polymer resin in a molten state. The molten polymer is then forced through the die head 11, thereby creating a tube extrusion. The hot tube extrusion enters and is stretched into the vacuum water tank 17, where the vacuum helps to pull the die head extrusion. A series of water spray nozzles in the vacuum water tank 17 spray water to cool the newly extruded tube, to aid solidification.
    [0051] [051] To assist in passing the extruded plastic tube through the tube forming apparatus, the pull-out Caterpillar 25 pulls the solidified tube from the water cooling tanks 21 and passes the tube through cutter 29. O cutter 29 cuts the tube at intervals as selected by the operator, to provide tube of desired length.
    [0052] [052] The finished tube is then transferred to a tube sliding table / tilting table 37 where the tube is prepared for storage and / or transportation. For flexible tubes, this may include winding the tube in the winding medium 39 as shown in figures 1 and 2. For tubes of larger diameter that cannot be wound, the tube can be lifted directly from the tube sliding table / tilting table 37 for a storage area or a pipe conveyor.
    [0053] [053] The components of modules 3 will now be described in further detail.
    [0054] [054] The feed and storage component of raw material 31 comprises portable silos 41, for example, with a capacity of 10 to 50 tons. As illustrated in figures 2, the silo 41 can be tilted in such a way that the raw material flows to the rear of the silo 41 to assist in the extraction of the raw material. The raw material is extracted from the silo by tubing or flexible hose with a suction unit, thereby aspirating the raw material from the silo, and supplying it to bulky bags 43 for temporary storage before feeding to the raw material dryer 7.
    [0055] [055] The raw material dryer 7 dries the plastic raw material before feeding into the extruder 9. The raw material dryer can use energy and heat from the power generation unit 33. In addition or alternatively, hot air can be extracted from the inside of the newly extruded tube, and recycled to the raw material dryer 7 for drying the plastic raw material. This can conserve energy by reducing or eliminating additional energy requirements for drying the raw material.
    [0056] [056] Extruder 9 can be a single or double screw extruder. This can be a commercially available unit, or a modified unit with reduced total output power to match the power generation unit 33. An appropriate extruder may include extruders manufactured by BATTENFELD-CINCINNATI GmbH. Located with the die head 11 there’s a tube head. The tube head may have the ability to produce single, double or triple layer tubes. Various tube sizes can be produced including 400 mm, 630 mm, 120 mm and 1600 mm diameter tubes.
    [0057] [057] Extruder line coloring medium 12 applies colored lines to the extruded tube for tube marking and identification purposes. Although only one extruder line 12 coloring medium is illustrated, in other embodiments, more than one extruder line 12 coloring medium can be used. As illustrated in figure 1, the extruder line coloring medium 12 when configured for use, projects from the first module 5. In this way, an additional container 13 can be disposed adjacent to the first module 5 to provide overhead protection to the medium. extruder line staining 12. In addition, container 13 can provide a working shelter for device 1 operators while allowing them to have access to device 1 components.
    [0058] [058] The vacuum water tank 17 comprises a cylindrical tank into which the newly extruded tube passes. Inside the tank is a series of sprays of water to cool the hot extruded plastic tube. The ends of the cylindrical tank are provided with a rubber cover or flaps. The flaps or rubber cover allow the extruded tube to enter the tank and at the same time form an atmospheric seal between the inside of the tank and the surrounding atmosphere. Vacuum pumps are arranged below the cylindrical tank to provide vacuum within the cylindrical tank. Water and energy for the tank are supplied by a respective electrical and water circuit, which will be further described below.
    [0059] [059] The cooling water tanks 21 comprise a cylindrical tank equipped with water sprays similar to the vacuum water tank 17. It would be recognized that it is possible to use multiple vacuum water tanks 17 in place of the cooling water tanks 21 .
    [0060] [060] The pull-out Caterpillar 25 comprises driven Caterpillar tracks that grab the outer surface of the finished tube to pull the tube from the cooling tanks 21.
    [0061] [061] Cutter 29 and winding means 39 can be commercially available units. Ideally, the winding medium 39 winds the tube with low ovality or deformation, like the winding means of Low Ovality Technology manufactured by PIPECOIL TECHNOLOGY LIMITED, UK.
    [0062] [062] The tube sliding table 37 is adapted to receive and support cut tube from cutter 29, and can comprise rollers to assist in sliding. Alternatively, or in combination, a tilt table can be used to receive, and transfer sections of cut tube to a tube trolley, or other component.
    [0063] [063] The power generation unit 33 comprises a diesel, gasoline or gas generator disposed in a 20 or 40 foot transport container. The container can also include a fuel tank for the generator. The module containing the power generation unit 33 can be adapted for external or internal use where it can be fitted with discharge and breathing tubing.
    [0064] [064] Energy from the power generation unit 33 is supplied to the first module 5, where it is distributed to subsequent modules 3 of the device 1. Each module 3 will have electrical power connectors to receive energy from a module, as well as distribute energy to another connected module. That is, the first module 5 will be electrically connected to the second module 15, which in turn is electrically connected to the third module 19, etc. This advantageously reduces the need to connect each individual module 3 with an electrical power line from the power generation unit 33, and simplifies assembly of the tube forming apparatus 1 at the production site. An exception is power supply to the cooling unit 35, where it can be advantageous to directly connect power from the power generation unit 33.
    [0065] [065] Alternatively, for production sites where power from the grid is available, device 1 can receive power from the grid source. Similar to the aforementioned modality, mains power can be supplied to the first module 5, where it will be distributed to subsequent modules 3.
    [0066] [066] The water cooling unit 35 may comprise an absorption chiller or a compressor chiller inside a 20 or 40 foot shipping container. The container can also include a water tank, and the water cooling unit can be adapted for external or internal use.
    [0067] [067] Optionally, the water cooling unit can be connected to, or co-located with, the power generation unit 35.
    [0068] [068] The water cooling unit 35 is connected by tube to the first module 5 and cools water to a closed circuit water supply to the device 1. The water circuit comprises a cold water line and a water line hot extending parallel to modules 5, 15 and 19. Modules 5, 15 and 19 have height-adjustable hot and cold tubes arranged therein, and the tubes are coupled together to form part of the closed water circuit. The closed water circuit provides water for the water cooling tanks 21, vacuum water tank 17 and components in module 5.
    [0069] [069] Alternatively, for production sites with an existing water circuit, device 1 can exchange cold and hot water with the existing water circuit. Similar to the water circuit described in the above modality, the water circuit can be connected to the first module 5, where it will be coupled to the tubes of subsequent modules 3.
    [0070] [070] Optionally, a corrugator, disposed in the first module 5 or in a separate module, can be positioned between the matrix head 11 and the vacuum water tank 17. The corrugator can be a commercially available system, like the series DROSSBACH HD manufactured by DROSSBACH GmbH, or series of ITIB corrugators manufactured by ITIB MACHINERY INTERNATIONAL SpA the corrugator, in use, moves forward and back axially to the extruded tube. In one embodiment, part of the corrugator may involve part of the matrix head 11. In an additional embodiment, part of the corrugator may project from a corrugator module and into the first module 5. Alternatively, the matrix head 11 may extend the from the first module 5 and protrude into the corrugator module.
    [0071] [071] Generally, each module 3 is provided with a lock 45 to allow adjacent modules 3 to be locked together. This ensures that the modules are correctly arranged in a mutual relationship during tube formation. In addition, an adjustment mechanism such as a winch can be used to pull the modules together. In this way, the modules can be placed in close proximity to each other, and the winch can then pull the modules together before the latches 45 are engaged.
    [0072] [072] The components within each module 3 are also adjustable in position or angle with respect to the module in which they are arranged. In one form, the components are supported by adjustable jacks on the top of the module floor. The adjustment can be mechanical, hydraulic, electromechanical or by another appropriate means of activation. In addition, the drive can be automated or semi-automated and controlled by a computer. The ability to adjust components in each module allows the components to be aligned when the modules themselves are not perfectly aligned.
    [0073] [073] A reference laser can be used to determine the relative positions of modules 3 or components, and provide information to allow corrections in the position of modules 3 or components in them. The laser can be mounted on either or both ends of the device 1, with the laser directed coaxially in relation to the geometrical axis of the tube extrusion.
    [0074] [074] In one embodiment, observation windows in the path of the laser beam can be attached to the components and / or modules. The location of the laser reflection on the panes will thus provide information on the position of the components and / or modules in relation to the reference laser. It should be recognized that other alignment methods can be used (for example, level reference indicators).
    [0075] [075] Modules 3 are generally 20-foot or 40-foot shipping containers. In one form, the sides or top of the modules may have doors to allow ventilation during the formation of tubes. In another form, the modules can be an open frame, and the top and / or sides can simply be left open during transport, or covered with a tarpaulin.
    [0076] [076] A second modality of the modular plastic tube forming apparatus, 101, is illustrated in figures 3 to 16. Features corresponding to those presented previously discussed are similarly numbered "100" preceding the similar feature.
    [0077] [077] In apparatus 101 of the second embodiment, the raw material dryer 107 is contained in a separate first module 105. The second module 106 contains the screw extruder 109 and the die head. The third module 115, fourth module 119 and fifth module 120 contain vacuum water tanks 117 and / or water cooling tanks 121. The sixth module 123 contains a water cooling tank 121 and a pull-out Caterpillar 125. The seventh module 127 contains a cutter 129 and a second pull-out Caterpillar 126. A second pull-out Caterpillar assists in pulling longer tubes.
    [0078] [078] The modules 103 of the device 101 generally comprise 20-foot and 40-foot modified containers. The modules 103 are supported by external supports 151, comprising adjustable jacks 153 supported by screw posts 155 embedded in the ground.
    [0079] [079] The external support 151 is shown in more detail in figures 17. Screw pile 155 is selected of an appropriate type, size and length to support the weight of modules 103 for the underlying soil. The adjustable jack 153 comprises an upper plate 157, lower plate 153 and adjustment pins 161. The adjustment pins 161 allow height adjustment of the supported modules 103. The upper plate 157 is of sufficient span to support two contiguous modules at their respective ends as illustrated in figure 6. However, it must be recognized that additional external supports 151 can be used in locations along the intermediate length of modules 103, as required. In addition, the span of the upper plate 157 also allows a degree of lateral displacement to allow adjacent modules 103 to be aligned.
    [0080] [080] Advantageously, the external supports 151 elevate the modules 103 above the underlying soil which assists in drainage if the apparatus 101 is located outdoors. In addition, the use of piles reduces the need for a flat hard surface to support the modules. Thus, less preparation is required at the pipe manufacturing site. In addition, the device can be mounted in areas with poor soil quality (for example, softer, sandy, loamy, loamy soil, etc.).
    [0081] [081] An internal support frame 163 for supporting components in a module 103 is best illustrated in figures 18. The support frame 163 comprises a frame body 165 and adjustable locking brackets 168. Adjustable locking brackets 168 are mountable on floor reinforcements 167 on the floor of modules 103. Adjustable locking brackets 168 allow the frame to be linear and angularly displaced as required to ensure alignment of components in modules 103.
    [0082] [082] The modules 103 will now be described with reference to figures 5 to 16. As illustrated in figure 7, the modules are reduced to standard shipping container sizes during transportation. This may include securing removable container ports 171. Doors 171 are typically removed prior to assembly of apparatus 101.
    [0083] [083] Figure 8 illustrates a sectional view of module 106, as an example of an open configuration using a module 103. Module 106 has a fold-down side wall 173, which folds down to support on a support external 151. The fold-down side wall 173 can then function as a floor for technicians to access apparatus 101.
    [0084] [084] Module 106 is also provided with an open top section 175. This allows device components 101 to extend above the top section of module 106 when configured for use. This also advantageously improves ventilation within the module. To ensure that the apparatus is protected from the weather, including rainwater and dust, a canvas awning around 177 is provided above and around the open top section 175, extending to the fold-down side wall 173. This ensures that technicians as well as components are protected from external elements. Figure 9 illustrates an alternative awning 178, where the awning extends outwardly from the top of module 127.
    [0085] [085] A cover similar to the rubber concertina is provided between the ends of each module 103. This ensures a weather, water and dustproof seal between adjoining modules 103. The cover can be fixed at each end of module 103 by bolts.
    [0086] [086] In modules 103 there are closed tops. The tops can be tilted towards the longitudinal center of the module, and to one side. This ensures that the rain drain is directed away from the cover by sealing the ends of the adjacent modules 103, thereby reducing the chance of water leaking into the modules 103.
    [0087] [087] The modules 103 are provided with ventilation louvers 179 to assist in the ventilation of the appliance 101. In addition, air conditioning units 181 can be provided to regulate the temperature inside the appliance 101.
    [0088] [088] Between modules 106 and 115, the vertical beams 183 and 185 at the contiguous ends can be removable. This facilitates access to the matrix head, which is located in the region of the contiguous ends. To maintain the structural integrity of modules 106 and 115, an additional vertical beam can be located in an alternate location.
    [0089] [089] To establish a modular plastic tube forming site, an appropriate site is first located. The location can be outdoors, under covered or indoor shelter. Generally, a flat floor, at least the size of the device is necessary. The soil can be a hard surface, such as bitumen or concrete. Alternatively, a screw post and adjustable jacks can be used to support the modules. This approach mentioned last is especially suitable for softer soil. The modules, in the form of transportable containers, are delivered on site. Since the containers have characteristics of standard 20 or 40 foot containers, existing transport and handling equipment can be used.
    [0090] [090] After modules 3 are transported to the production site, the modules can be configured from their transport state to a tube production state. This may include opening and / or removing container doors 171, and removing any seals or protective equipment required during transportation.
    [0091] [091] Modules 3 are then arranged as needed in the predetermined mode at the production site. The modules 3 are then pulled into close proximity to each other using a winch, and then locked together.
    [0092] [092] Alternatively, two modules are first arranged in the predetermined mode (above) on the spot. The two modules are then pulled into close proximity using a winch, and then locked together. An additional module is then arranged as required in the predetermined mode.
    [0093] [093] The additional module is then positioned in close proximity to the first two modules that have been locked. The additional module is then pulled towards the first two modules with a winch and then locked. This can be repeated until all required modules have been arranged and locked, as needed.
    [0094] [094] When all modules have been arranged and locked, the components supported by the modules can then be adjusted in position and aligned with each other. As described above, this can be done manually or autonomously and can be assisted with a reference laser.
    [0095] [095] The electrical connectors and the coupling for the water pipes between each module 3 are then connected, to supply power and water to the modules. After completing this, and water, energy and plastic raw materials are supplied to the apparatus 1, the plastic pipe forming site is established and the pipe forming operations can begin.
    [0096] [096] When the plastic tube forming on site is completed, the tube forming apparatus can be moved to a new location. This involves decoupling the electrical connectors, water pipes and modules. The modules are then configured in a transportable state, such as securing and / or closing doors, adding protective or sealing equipment, and adjusting the position of components to fit the dimensions of the shipping container. The modules can then be transported to the new production site, and the method of establishing a plastic tube forming site described above is repeated.
    [0097] [097] In projects where a long continuous pipe is required, the plastic pipe forming apparatus can be intermittently moved along the proposed pipe as the pipe is laid. That is, a first mobile pipe manufacturing site is located near the beginning of the pipe, and the pipe is formed, transported and the pipe is seated. As the front of the pipe laying site advances, the formed pipe needs to be transported additionally from the pipe manufacturing site to the pipe laying site. Thus, the time and cost of transporting the tube increases. It can then be economical to relocate the tube forming apparatus 1 to another location closer to the pipe laying site in advance, or even in front of it. Alternatively, a second tube forming apparatus can be located at the new location, with the first apparatus being readied for a third location, etc. in this way the apparatus provides a mobile tube manufacturing site which advantageously allows the tube production to accompany the step of the tube laying site.
