Product description
Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strips into pipe blanks at a certain spiral angle (called forming angle), and then welding the pipe seams. It can be made of narrower pipes. Strip steel produces large diameter steel pipes. Its specifications are expressed as outer diameter * wall thickness. The welded pipe should ensure that the hydraulic pressure test, tensile strength and cold bending performance of the weld meet the regulations.
