    BACKGROUND AND PRIOR ART It has been the case since before that metal pipes or parts of a metal pipe, for example a ridge, can be surface treated chemically, by, for example, phosphating, in order to improve the rudder's, friction, grouting and corrosion properties. A conventional surface treatment method meant that part of the pipe with the rudder passage with the help of a traverse was sunk into a tank with surface treatment agent, after which the pipe was lifted up and rinsed off with a shelling agent.
    In an alternative method, known from the patent document US4828796, surface treatment agents and rinsing agents are supplied to the pipe which is to be surface treated via an inner or an outer arranged tube. During surface treatment of the inside of the nipple, a nipple of smaller diameter is arranged inside the nipple to be surface-treated, after which surface treatment agents and rinsing agents are supplied to the inside of the nipple via the gap between the two tubes. For external surface treatment of the rudder, the rudder, the outside of which is to be surface-treated, is placed inside a pipe with a larger diameter. The amount of surface treatment agent and rinsing agent can be limited to the space in the gap between the two tubes with the said technique.
    Problems associated with said surface treatment procedures can be summarized as procedures; are complicated, require masking of parts that are not to be surface treated, entailed heavy lifting with traverse, entailed discharge of environmentally harmful substances to the environment. 1283 SE2 OBJECT OF THE INVENTION AND ITS FEATURES A main object of the present invention has been to provide a simple, things and environmentally friendly surface treatment equipment for surface treatment of pipes and pipe parts.

    DETAILED DESCRIPTION OF THE EMBODIMENT The invention relates to a surface treatment equipment for surface treatment of metal pipes. Preferably, this refers to a surface treatment equipment for phosphating internal or external pipes. Phosphating means that a surface treatment solution comprising phosphoric acid is applied to the metal surface to be surface treated, a phosphate layer being formed by the phosphoric acid reacting chemically with the metal surface of the tube. Suitable surface treatment solutions for phosphating include an aqueous solution of phosphoric acid and various metal phosphates, e.g. 5.0 - 10.0% by weight of orthophosphoric acid, 10.0 - 25.0% by weight of manganese phosphate 0.25 - 0.50% by weight of nickel nitrate and 2.5 - 10.0% by weight of manganese nitrate. Phosphating Normally followed by some type of finishing e.g. oiling or varnishing. Rudder parts with high strength and hardness also need heat treatment to reduce the risk of wet spraying. The phosphate layer is crystalline and porous and due to its chemical bond to the parent metal it is firmly anchored. Furthermore, the phosphate layer is electrically non-conductive and passivates ddrfOr the metal surface, i.e. counteracts rust formation. 1283 SE6 Furthermore, the phosphate layer, at high surface pressures, is lubricating, which increases the wear resistance and prevents direct metallic contact between sliding surfaces. Before starting the phosphating, the area to be phosphated is cleaned via the following measures; cleaning with blasting, cleaning with compressed air, washing with acetone, or similar more environmentally friendly alternatives, cleaning with compressed air and possible preheating. After thorough phosphating, the phosphated area is treated via the following 10 Atgarder, water flushing, purge with compressed air, cooling and oiling of the phosphated area.
