Product Description

The crack resistance of spiral welded pipe is better than that of straight welded pipe. The spiral angle of spiral welded pipe is generally 50-75 degrees, so the synthetic stress of spiral welded joint is 60-85% of the main stress of straight welded pipe. Under the same working pressure, the wall thickness of spiral welded pipe with the same pipe diameter is smaller than that of straight welded pipe. The size is accurate. Generally, the diameter tolerance is not more than 0.12%, the deflection is less than 1 / 2000, and the ovality is less than 1%. Generally, the sizing and straightening process can be omitted.
