    How to identify the quality of large diameter spiral welded pipe?

    Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is a low-carbon structural steel or low-alloy structural steel strip rolled into a tube blank at a certain helical angle (called a forming angle), also known as a spiral tube or a spiral body. The outer diameter of the spiral tub...
