A spiral pipe mill machine 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.

We are your reliable China spiral welded pipe factory. If you are looking for spiral pipe making machine for spiral welded steel pipe, don't hesitate to contact us. As one of the professional spiral pipe manufacturers in China, Hangzhou Roll Forming Technology sells welded tube mills at reasonable prices.
