spiral pipe hangers A. During the blasting of spiral welded pipe, since the normal stress and synthetic stress on the welding seam are relatively small, the blasting hole generally does not originate from the spiral welding seam, and its safety is higher than that of straight welded pipe.B. When there is a parallel defect near the spiral weld, the risk of expansion of the spiral weld is less than that of the straight weld due to the small force on the spiral weld.C. Since the radial stress is the maximum stress existing on the steel pipe, the maximum load will be borne when the weld is in the direction of vertical stress.That is, the straight seam bears the largest load, the circumferential weld bears the smallest load, and the spiral seam is between them.

The interface of spiral welded steel pipe production line is far lower than that of submerged arc welded straight pipe production line, and the relative price of finished steel pipe is also lower than that of submerged arc welded straight pipe.2. Different diameters of steel tubes can be produced with the same width of strip steel;The afraid type is easy to adjust and change the specification, which is suitable for mass production and small batch production. The production process is easy to realize mechanization, automation and continuity.3, it can produce spiral welded steel pipe specifications from Ф 219-1420 - mm diameter, even up to 2540 mm.The diameter of submerged arc welding straight joint steel pipe is obviously restricted by the width of the plate.
The Process Flow
has more than ten years history company which located in Lecong Iron and Steel World, a well-known steel distribution center in China, with superior geographical position and convenient water and land transportation.
We are a direct-selling manufacturer specializing in the research and development of spiral steel pipes, steel coiled pipes, anti-corrosion steel pipes inside and outside. Since its inception, the company has been guided by a brand-new thinking of steel pipe product market based on the business philosophy of honesty, pragmatism and knowledge-seeking.
