Weld leveling of straight seam steel pipe (lsaw/erw): Due to the impact of the welding current and the influence of gravity, the internal weld of the pipe will protrude, and the external weld will also sag. If these problems are used in an ordinary low-pressure fluid environment, they will not be affected. If it is used in high temperature,…
Read MoreComparison of ERW pipe and seamless pipe (SMLS): (1) Superior tube blank quality Compared with the tube blank of SMLS steel pipe, the design of chemical composition of high frequency welded pipe (ERW) is more scientific and reasonable. ERW special steel grades are characterized by high purity. Through de-S, de-P, degassing, Ca treatment and other methods, the content of…
