Spiral tube
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 spiral angle (called forming angle), and then welding the pipe seams made. This manufacturing method allows the production of larger diameter steel pipes using narrower strips of steel‌
