Introduction
The spiral welded pipe mill is used to roll low carbon steel and low alloy steel strips into tubes at specific angles, and then further weld it into a steel pipe using a submerged arc welder. Large diameter pipes can be produced with the narrow steel strip.

Product Applications
1. Liquid Delivery: water supply and drainage
2. Gas Delivery: coal gas, steam and LPG
3. Structural use: piling pipes, structural pipes in bridges, docks, roads and other construction
