Spiral Tube
Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. , which can produce large-diameter steel pipes from narrower strips.
Spiral pipes are mainly used for oil and natural gas pipelines, and their specifications are expressed by outer diameter * wall thickness. There are single-side welded and double-sided welded spiral pipes, and the welded pipes should ensure that the hydraulic test, the tensile strength of the weld and the cold bending performance meet the regulations.
