High Quality API 5L GR.B Carbon Spiral Welded SSAW Steel Pipe

Spiral welded pipe: It is made by rolling a low carbon carbon structural steel or a low alloy structural steel strip into a tube blank at a certain angle of a helix (called a forming angle), and then welding the pipe seam, which can be used in a narrower manner. Strip steel for the production of large diameter steel pipes. The specification shall be expressed by the outer diameter * wall thickness. The welded pipe shall ensure that the hydraulic pressure test, the tensile strength of the weld and the cold bending performance are in compliance with the regulations.
