51 steel pipe network news: can use straight seam steel pipe instead of seamless pipe
51 steel pipe network news: whether the use of straight seam steel pipe in place of seamless pipe structure should be the same in theory, the difference is not great, straight seam welded pipe is not as good as seamless pipe rule, the shape of the pipe may not be centroid, so use When working as a compressive component, special attention should be paid to the fact that there is a relatively high probability of weld defects in the weld pipe. The important parts cannot replace the seamless pipe. The seamless pipe is limited by the processing technology. The pipe wall thickness cannot be made very thin (same pipe diameter The average wall thickness of the seamless pipe is thicker than that of the welded pipe. In many cases, the seamless pipe material is not as efficient as the welded pipe, especially the large-diameter pipe. The biggest difference between seamless tubes and welded tubes is the use of pressure gas or liquid transport (DN).
