Large Diameter Spiral Pipe Mill

Spiral pipe mill is used to roll the low carbon steel/ low alloy steel strip into a tube by a certain forming angle, further weld it into steel pipe by submerged arc welder.

Large diameter pipes can be produced with a narrow steel strip.

Large Diameter Spiral Pipe Mill Applications


  • For liquid delivery: water supply& drainage; 

  • For gas delivery: coal gas, steam and LPG; 

  • For structural use: piling pipe, structural pipe in the field of bridge, dock, road, and construction, etc.
