Spiral pipe (SSAW) is a spiral seam carbon steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in water supply engineering, petrochemical, chemical, electric power, agricultural Fluid transportation in the fields of irrigation and municipal buildings: water supply, drainage, sewage treatment…
Read MoreCarbon steel welded pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). The carbon steel welded pipes produced by these three processes have their own positioning in the application field because of their different raw materials, forming processes, caliber size and quality. 1. Straight seam…

Read MoreThe outer coating of welded pipe FBE fused epoxy powder (FUSION BOND EPOXY) anti-corrosion steel pipe is a new type of anti-corrosion coating developed in the past 30 years. The coating has the characteristics of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance, and has been widely used abroad. Powder coating is…
Read MoreSurface heat treatment is divided into two categories: one is surface quenching and tempering heat treatment, and the other is chemical heat treatment. Common hardness testing methods are as follows: 1. Surface quenching and tempering heat treatment The surface quenching and tempering heat treatment of seamless steel pipes is usually carried out by induction heating or flame heating. The…
Read MoreERW welded pipe is formed by using the skin effect and proximity effect of high-frequency current to rapidly heat the edge of the formed pipe blank to the welding temperature and then extrude and weld it. According to the different feeding methods, ERW welded pipes can be divided into high frequency contact welding and high frequency induction welding. Both…
Read MoreSpiral pipe derusting and anti-corrosion process: Derusting is an important part of the anti-corrosion process of spiral welded pipe pipelines. At present, there are many derusting methods, such as manual derusting, sand blasting and pickling and so on. Among them, manual rust removal, mechanical rust removal and painting rust removal (anti-corrosion brushing oil) are relatively common rust removal methods….
Read MoreSpiral pipe (SSAW) is also called spiral steel pipe or spiral welded pipe. It is made by rolling a low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain helical angle (called a forming angle), and then welding the tube seams. It can produce large diameter pipes from narrower strips. Spiral pipes are mainly…
