ERW Steel Pipe Process Performance Inspection Standards

Jul 14, 2020ERW Steel Pipe Process Performance Inspection Standards. 1. Bending test Bending test should be carried out on steel tubes with an outer diameter less than or equal to 50mm. The bending angle is 90°, the bending radius is equal to 6 times the outer diameter of the tube. The weld is located at the outermost part of the bend.ERW Steel Pipe and Tube, ERW CasingHigh-frequency straight seam electric-resistance welded steel pipe(erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same ERW steel tube steel pipe processERW Welded Steel Pipes

In the Electric resistance welded (ERW) manufacturing process, the pipe is manufactured bycold-forming a flat sheet of steel into a cylindrical shape. Then the current is passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.WHAT ARE ERW/GP/GI/MS PIPES & TUBESTHEIR MANUFA
