Welded Pipe
The production process of longitudinal welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrower blank, and can also produce welded pipe with different pipe diameter with blank of the same width. However, compared with the straight seam pipe with the same length, the weld length increases by 30~100%, and the production speed is low.
API 5L steel pipe is seamless and welded pipe for pipeline transportation systems in the oil and gas industry. It consists of two product specification levels (PSL1 and PSL2), and the welded pipe is manufactured using the CW, LFW, HFW, LW, SAWL, SAWH, COWL, and COWH processes.
