The longitudinal seam steel pipe is the steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, electric welded thin wall pipe, transformer cooling tubing and so on. Longitudinal welded pipe production process is simple, high production efficiency, low cost, rapid development.
The longitudinal welded pipe is generally higher than that of straight welded pipe. The welded pipe with larger diameter can be produced with narrow blank, and the welded pipe with different diameter can also be produced with the same width of blank. However, compared with the same length of straight seam pipe, the weld length increases by 30~100%, and the production speed is lower.
