Large Diameter Spiral Pipe Mill

A spiral pipe mill is used to roll the low carbon steel/ low alloy steel strip into a tube by a certain forming angle and further weld it into a steel pipe by submerged arc welder. With the assistance of our spiral tube forming machines, large diameter pipes can be produced with a narrow steel strip. As one of the professional spiral pipe manufacturers in China, Hangzhou Roll Forming Technology sells welded tube mills at reasonable prices.
