Introduction to Spiral Pipe Products
Spiral pipe, also known as spiral welded steel pipe, is a type of steel pipe produced by winding a strip of low-carbon structural steel or low-alloy structural steel into a pipe billet at a certain spiral angle (called the forming angle), and then welding the pipe seam. This type of steel pipe can produce large-diameter pipes using narrower strips and has a wide range of applications.
