the production process of welded steel pipe, welded steel pipe
(2) spiral welded steel pipe: Longitudinal strength generally higher than that, can narrow the larger diameter pipe billet production, you can also use the same width of the billet production of welded pipes of different diameter; but with the same lengthcompared to straight seam pipe, spiral welded steel pipe weld length of 30 to 100%, and lower production rate; Therefore, the smaller diameter pipe actually use straight seam welded, large diameter spiral welded pipe Why did a spiral welded gas pipe rupture?A spiral-welded pipe carrying sour gas ruptured only a few weeks after commissioning. The failures, which occurred preferentially adjacent to the welds, were due to H2S corrosion, which saturated the metal with hydrogen and produced the step-like cracking described in the previous section, but not necessarily restricted to the weld region.See all results for this questionWhat kind of pipe is a spiral weld?Spiral Weld Pipe. Spiral Weld Pipe, as the name implies, is a steel pipe that has a seam running its entire length in a spiral form. In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications.See all results for this question
