Explore the differencea between straight seam steel pipe and spiral steel pipe steel plate

From the point of view of welding process, the welding method of straight seam Steel pipe and spiral steel pipe is the same. However, in the actual welding process, a large number of T-shaped welds often appear in the straight seam welded pipe. In such welds, there are often some residual stresses. It is precisely because these residual stresses increase the likelihood of cracks in straight seam steel pipes.

Compared with spiral steel pipe, the production process of straight seam steel pipe is much simpler. The production process of straight seam steel pipe is mainly divided into two types, one is high frequency welded straight seam steel pipe, and the other is submerged arc welded straight seam steel pipe. It is precisely because of these characteristics of the simple production process of straight seam steel pipes that the production efficiency of straight seam steel pipes is high, the cost is low, and the speed of development is also very rapid.

Compared with straight seam steel pipes, spiral steel pipes have certain advantages in strength. The main process of producing spiral steel pipe is submerged arc welding. Spiral steel pipes can be used to produce welded pipes of different diameters from billets of the same width. It can also be used to produce larger diameter welded pipes from narrower billets.
