Spiral Tube

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made of low-carbon structural steel or low-alloy structural steel strip rolled into a tube blank at a certain spiral angle, and then the tube seam is welded. ‌ This structure makes it possible to produce large diameter steel pipes using narrower strips. The specifications of spiral pipes are usually expressed in terms of outer diameter and wall thickness.
