Ett konventionellt ytbehandlingsforfarande innebar att roret eller en del av roret sanks ner i en tank fylld med ytbehandlingsmedel, med hjalp av travers, varefter roret lyfts upp ur tanken och spolas av med ett skoljmedel. BACKGROUND AND PRIOR ART It has long been known that a metal pipe or part of a metal pipe, for example a pipe pipe, can be chemically surface treated, for example by phosphating, in order to improve friction, notching and corrosion properties. A conventional surface treatment procedure meant that the rudder or part of the rudder sank into a tank filled with surface treatment agent, with the aid of a traverse, after which the rudder was lifted out of the tank and rinsed off with a rinsing agent.

Ytbehandling av ett rors insida genomfors via ett ror med mindre diameter anordnad inne i roret som skall ytbehandlas, varvid ytbehandlingsmedel och skoljmedel tillfors rorets insida via spalten mellan de tvA roren. Vid ytbehandling av ett rors utsida placeras roret vars utsida skall ytbehandlas inne i ett ror med storre diameter, varefter ytbehandlingsmedel och skoljmedel tillfors rorets insida via spalten mellan de tva roren. Mangden ytbehandlingsmedel och skoljmedel kan genom namnda teknik begransas till utrymmet i spalten mellan de tva roren. In an alternative surface treatment method, edge through the patent document US4828796, a surface treatment agent and rinsing agent are supplied with a tube which is to be surface treated via an inner and / or an outer arranged tube. Surface treatment of the inside of a pipe is carried out via a pipe of smaller diameter arranged inside the pipe to be surface treated, wherein surface treatment agent and rinsing agent are supplied to the inside of the pipe via the gap between the two pipes. When surface treatment of the outside of a pipe, the pipe whose outside is to be surface treated is placed inside a pipe with a larger diameter, after which surface treatment agent and rinsing agent are supplied to the inside of the pipe via the gap between the two pipes. The amount of surface treatment agent and rinsing agent can be limited by the said technique to the space in the gap between the two tubes.

DETAILED DESCRIPTION OF THE EMBODIMENT The invention relates to a surface treatment equipment for surface treatment of metal pipes. More preferably, it refers to a surface treatment equipment for phosphating internal or external pipe passages. Phosphating means that a surface treatment solution comprising phosphoric acid is applied to the metal surface to be surface treated, whereby a phosphate layer is 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 water production. The phosphate layer is crystalline and porous and due to its chemical bond to the parent metal it is firmly anchored. The phosphate layer is furthermore electrically non-conductive and therefore passivates the metal surface, i.e. counteracts rust formation. Furthermore, the phosphate layer, at high surface pressures, is lubricating, which increases the wear resistance and prevents direct metallic contact between sliding surfaces.

Innan fosfateringen paborjas rengors omradet som skall 5 fosfateras via foljande atgarder; rengoring med blastring, renblasning med tryckluft, tvattning med aceton, eller liknande mer miljOvanliga alternativ, renblasning med tryckluft och eventuell forvarmning. Efter genomford fosfatering efterbehandlas det fosfaterade omradet via 10 foljande atgarder, vattenspolning, renblasning med tryckluft, avsvalning samt anoljning av det fosfaterade omradet. Before the phosphating is started, the area to be phosphated is cleaned via the following procedures; cleaning with blasting, cleaning with compressed air, washing with acetone, or similar more environmental Unusual alternatives, cleaning with compressed air and possible preheating. After genomic phosphating, the phosphated area is post-treated via the following procedures, water rinsing, purge with compressed air, cooling and oiling of the phosphated area.
