Spiral steel pipe forming process, the steel plate to uniform deformation, residual stress, surface not to produce scratches, so making spiral steel pipe, steel plate selection carefully surface to even don't have a scratch. Processing spiral steel pipe on the scope of the size of diameter and wall thickness is more flexibility, especially in the production of high grade thick wall tube, especially small and medium caliber thick wall tube, has incomparable advantage over other techniques, can meet the requirements of users in the aspect of spiral steel pipe specifications more. Spiral steel pipe diameter and the size range to flexible, has great advantages, using their own set of more extensive user demand, popularization and promotion is the spiral steel pipe can be.
