Spiral welded pipe
Spiral welded pipe: It is made by rolling low carbon carbon structural steel or low alloy structural steel strip at a certain helical angle (called forming angle) into a tube blank, and then welding the pipe seams. Strip steel produces large diameter pipes. Its specifications are expressed by outer diameter * wall thickness, and the welded pipe should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance meet the requirements. Spiral welded pipes are used for oil and gas transportation, pipe piles, bridge piers, etc. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes.
