Spiral welded pipe

Product Introduction

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low alloy structural steel strips at a certain spiral Angle (called the forming Angle) into a tube blank, and then welding the pipe seams together. It can produce large-diameter steel pipes with relatively narrow steel strips. Its specifications are indicated by outer diameter * wall thickness. Welded pipes should ensure that the hydrostatic test, tensile strength of the weld seam and cold bending performance comply with the regulations.
