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. Our pipe mill
for sale is of high quality and can be applied in many fields.

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.
