Spiral welded steel pipe
Rolling low carbon steel or low-alloy structural steel strip into a tube at a certain helix angle (called molding angle) and then made seam-welded pipe. It can produce a large diameter steel pipe use narrow steel strips. Its specifications described as "diameter * wall thickness", which said the pipe should ensure fit the requirements of hydrostatic testing, tensile strength and cold bending properties.
