Straight Seam Pipe

Straight seam steel pipe is a steel pipe whose weld is parallel to its longitudinal direction. It is usually divided into metric welded steel pipe, welded thin wall pipe, transformer cooling oil pipe and so on. Straight seam welded pipe production technology is simple, high production efficiency, low cost, rapid development. Spiral welded pipe generally has higher strength than straight welded pipe. Welded pipe with larger pipe diameter can be produced from narrow blank, and welded pipe with different pipe diameters can also be produced from blank of the same width. However, compared with the same length of straight seam pipe, the weld length is increased by 30~100%, and the production speed is lower.
