Spiral Welded Pipe
The low-carbon carbon structural steel or low-alloy structural steel strip is rolled into a tube blank at a certain spiral angle (called forming angle), and then the tube seams are welded together. It can produce large-diameter steel pipes with narrower strips. Its specifications are expressed by outer diameter * wall thickness. The welded pipe should ensure that the water pressure test, tensile strength of the weld and cold bending performance meet the requirements.
Spiral welded pipe
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.
