    DESCRIPTION
    Portable device for monitoring, testing, incorporation of additives and control of pipes, materials and fluids.
    Field of the Invention
    The present invention belongs to the field of monitoring, testing, incorporation of additives and control of pipes, their materials and fluids, and is applicable in the three productive sectors: primary, secondary and tertiary:
    a) in the primary sector (basic production): agribusiness, livestock, aquaculture and mining sector;
    b) in the secondary sector: in all industrial fields (chemical industry, paper production of electricity, etc.), and in all fields of construction where there is liquid circulation such as the naval sector (military navy, merchant marine, fishing and sports marine), air sector (sports, civil transport of cargo and passengers, and military), and land sector (competition vehicles, cars, buses, cranes, locomotives, etc.);
    c) in the tertiary sector (services): in the fields of commerce and services provided to people, such as the pharmaceutical, health, food, etc.
    Background of the invention
    The search to improve the efficiency of the materials (of the fluids and their useful life) that work in tubular elements and in equipment that work with fluids that are subjected to heat transfer, forces to carry out detailed tests and studies of the behavior of the materials and fluids that come into contact with them, as well as their reactions.
    Since the first industrial revolution started at the end of the 17th century in the United Kingdom, with the use of steam-working machines, the need was born to monitor the processes in which materials of different configuration work in contact with fluids that They are subjected to heat transfer, to perform: tests, incorporation of additives, control in the pipes and equipment that work with different materials and that are in contact with fluids and steam.
    In 1934, John C. Raisley, presented the first heat exchanger with the US2046968 A patent, and all the productive sectors of society have benefited from the benefits and features that incorporate these thermal devices for society.
    From that moment, science reinforces the study to improve the materials and fluids that are in contact with each other, so that the fouling reactions, the actions and reactions that occur between materials and fluids, are minorized and thus lower the maintenance operations and extend the durability of materials and fluids.
    Document US3486996, shows a probe to perform corrosion tests on materials by correlating the polarization characteristics of metals with the corrosion rate. However, this invention is not portable to any

    place of an installation, since it requires auxiliary elements (of which it lacks) to integrate it into the installation under study.
    Document US5895843, is a sensor device for monitoring corrosion conditions in a material. However, due to its constructive configuration based on glass, it presents many restrictions, among them, that the device has to adapt to each material to be tested, in addition to the fact that it does not continuously monitor and is hardly portable to any site of a facility to carry out studies.
    Document US4521864, is a method and device for measuring the thickness of fouling that occurs in a hydraulic system. However, this technique and procedure do not presently present an efficient or accurate degree of monitoring in processes that operate continuously. Nor is it easily integrated anywhere in an installation.
    The document US6077418, is a device to monitor the corrosion of materials by preparing a test tube of the material to perform the corrosion monitoring, but it presents the problem of not working integrated in the installation since it does so in isolation. Therefore, you have to obtain a test sample of material to study and perform laboratory monitoring.
    Document US4766553, is a device for monitoring the fouling that occurs in a heat exchanger, by means of different transmitters that need power to perform temperature measurements. This device analyzes the thermal difference that the materials suffer when they are new or clean until they begin to get fouled by the contact of the fluids. It presents a focused monitoring and despite the complexity of its sensors generates approximate measurement values. This device does not monitor the consequences of exposure of fluids in materials, such as oxidation or corrosion. It is also not portable anywhere in an installation or equipment and its use is restricted to heat exchanger installations.
    Document ES2149695 B1, is a restricted device for monitoring the simulation of the behavior of material specimens of the heat pipes of a heat exchanger. The monitoring is carried out in combination, directly and indirectly. Indirectly, the resistance to heat transfer and the friction factor is monitored and by direct measurements it monitors the thickness and the physical, chemical and biological characteristics of the fouling that adheres to the inner surface of some material specimens, of geometric characteristics and of operation, similar to those of a heat pipe of a heat exchanger-condenser of a real plant, without implying the shutdown of the plant. However, it is a device for monitoring heat exchangers, does not work on site in the installation to be monitored and is not easily portable.
    Document US5280717 A shows an instrument for testing extrusion (destructive testing) of adhesion of pastes (fouling, among others) by exposure of fluids in materials. It is an ingenuity that tests material specimens but does not allow the study of fluids constants or materials such as temperature, flow, pressures, differences and pH changes, etc. In addition, it is not easily portable either.
    The document US6220748 B1, shows a method and an ingenuity that allows to measure, only, the adhesion and fouling that have produced by exposure the fluids in the materials, by means of a movable probe that makes differential measurements of

    temperature to determine the characteristics of the material in aluminum fusion baths. It is a device that is directed exclusively for the production of aluminum and is not portable.
    WO2007028949 A1, describes a method and an instrument for introducing a sample of a material for testing by means of a hole in the material to be tested and placing the sample in a capsule (cap). Similarly, patents US-A-2723554, US-A-4567774, US-A-2003/0037620, US-A-2003/0054740 and EP-A-1158290 are written. In these documents, the main material in which the test is to be performed must be altered. The samples are of the same material to be tested, but not with the same form of the material to be monitored or tested, nor do they provide the study or control of fundamental parameters such as temperature, pressure, flow rate, pH changes, etc. Nor is this invention portable and easy to implant in any part of a device that works with fluids.
    Document MX20 15007272 (A), shows a method and apparatus for calculating the dirt factor and / or thickness of inverse soluble inlays in heat transfer equipment in a static way, without the possibility of testing different materials. For the test method, it incorporates a test cell and it is not possible to carry out the test in a continuous way and also in situ (portability), to carry out tests or tests in the processes as it is difficult to transport.
    Document US4766553 shows a system for monitoring the fouling and loss of performance of the materials of the heat exchange surfaces in heat exchangers. One of the main objectives of this invention is to provide a performance monitor to generate a dirt factor from a heat exchanger. For this purpose, this ingenuity is endowed with a complex system to perform its task, it is not accurate in monitoring and it is not portable either. To carry out the materials test, this device does not have a system for the replacement of thermal tubes that come into contact with fluids and to be able to test other materials, in addition, it is not detailed that there is a system for taking fouling samples in the tubes
    Document ES2149695A1, shows a combined monitor for direct and indirect measurement of fouling in materials, restricted to heat exchange processes. The invention consists of a system of direct and indirect measurement of the heat exchange process between two fluids, one of which causes the growth of biological film inside the tubes of a tubular beam (fouling) because that fluid Contains microorganisms The system continuously assesses the growth of the fouling adhered to the inner surface of the tube of an exchanger and consists of two differential parts: the one that monitors fouling by means of a direct system (biological film sample), and the one that controls this undesirable phenomenon indirectly, by means of the measurement of the friction factor and the resistance to heat transfer. However, this device is limited to the study of fouling, not taking into account the rest of fouls that occur in the industry. It does not have a system for replacing the tubes and being able to test different materials. Apart from that, it does not present the possibility of monitoring and testing specimens for fouling analysis inside the tubes.

    Elements 11, 12, 13, detailed below, allow the device to be portable.
    The first element 11 is a hollow piece whose material is preferably stainless steel.

The hollow piece preferably has a tubular shape. This second element 12 must be tight against high temperatures and high pressures.
    This second element 12 comprises machined connections 17, preferably with thread, along its contour in order to connect sensors, for example: temperature, pressure, flow measurement, pH measurement, or measurement of the viscosity of the fluid. One skilled in the art will understand that connections that are not used during the test can be sealed by blind plugs, preferably threaded.
    One of the ends of the second element 12 is open and comprises joining means, preferably a thread, configured to, during the test, be joined (or scratched) to the end of the first element 11 not connected to the installation.

    The device of the invention allows non-destructive tests to be carried out under real conditions in situ, in which it is possible to monitor, test, add additives (physically, chemically and biologically) by means of solid substances that can be housed in the shaped test tube of ring, so that they are dissolving in function of the time, or physical variables, the losses of efficiency in the productive processes in which they work with pipes and devices that work with fluids, as well as in the materials and in the fluids that are Contact these. In addition, due to its design, it can work with high temperatures and pressures guaranteeing the tightness of the fluid to be monitored, tested, additives and control.
    The characteristic of being portable to any place of an installation, makes it ideal to place it in any part of a process or a mechanism that works with fluids. In addition, the device of the invention is integrable to any installation, as it can be attached to any pipe anywhere in an installation. Also, and because it is possible to test or control any material, the device of the invention should not be adapted to each material to be tested.
    In this way, the behavior of different materials and different fluids can be tested before the construction of equipment (design phase) or modification of existing device installations that have processes in which fluids intervene.
