Spiral steel pipe Carbon Black Iron Welded Sch40 Steel Tube Pipe for Building Materi

Spiral steel pipe is a kind of spiral steel pipe formed by winding strip steel or coiled plate according to spiral shape and welding the inner seam and outer seam with double-sided submerged arc active welding. It can be widely used in water, electricity, chemical industry and other professional production for the following reasons. By changing the forming viewpoint, steel pipes of various diameters can be produced with strip steel of the same width, which is easy to adjust. Because the spiral tube is formed in a continuous zigzag way, the length of the spiral tube is not constrained and can be determined at will. The spiral weld is evenly distributed on the circumference of the whole spiral pipe, so the spiral pipe has high scale accuracy and strong strength. It is easy to change the scale and is suitable for the production of small batches and various types of spiral tubes.
