ERW Structural Pipe

The pipe is made of steel coils and the weld is parallel to the pipe. It is one of the most versatile tools in agricultural, industrial and construction activities. The manufacturing process of ERW steel pipe includes HFW. ERW welding includes low frequency, medium frequency and high frequency welding. It is a kind of pipeline widely used in oil, natural gas, coal gas, machinery, construction, aviation, power and other industries. Features ERW structural pipe is made of a whole piece of metal with no seams on the surface. The pressure welding method without filler metal is adopted, and no other components are filled in the weld. The skin effect and proximity effect of high-frequency current make the edge of the plate instantly heated to the welding temperature, so that the weld is formed by extrusion of the extrusion roller. High-quality steel pipes require heat treatment of the weld to refine the organization of the weld area. The outer diameter of ERW structural pipe is 21.3mm-610mm, and the wall thickness is 1mm-22mm. In addition, its length ranges from 0.5mtr to 20mtr. You can choose from three types of terminals, so it is more versatile. Standard: ASTM A53/A53M, ASTM A252, EN10219-1, AS/NZS 1163, AS/NZS 1074, ASTM A500, Structural pipe: can be used for various structural parts, fluid conveying pipelines and other buildings.
