The introduction of the Spiral welded pipe line

The spiral welded pipe unit is a steel pipe formed by rolling a low carbon structural steel or a low alloy structural steel steel strip into a tube blank by a molding machine at a certain forming angle, and then welding the spiral pipe joint by a submerged arc welding machine. The advantage is that a large diameter steel pipe can be produced with a narrow strip.
