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 pipe blank at a certain angle of the spiral line (called forming angle), and then welding the pipe seam together. It can produce large-diameter steel pipes with narrower strip steel.
