China Spiral Steel Pipe is used in industry. Which is to put the low carbon structural steel and low alloy steel strip according to certain helix Angle rolled tube billet, and then welded pipe joints made of. Now let me tell you a little bit about the characteristics of the helical tube.
The production process of welded pipe is simple, the production efficiency is high, the cost is low, the development is fast. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can be used to produce welded pipe with a larger diameter with a narrow blank. However, compared with the straight seam pipe of the same length, the weld length increases by 30-100%, and the production speed is low. Therefore, the welding pipe with smaller diameter is mostly welded by straight seam, while the welding pipe with larger diameter is mostly welded by spiral.
