Aug 22, 2018 · The welded steel pipes are mainly divided into three processes:straight seam electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW)..
Comparison of ERW and LSAW Steel Pipes3. The ERW pipe is a "high-frequency resistance welded steel pipe", which is different from the ordinary welding pipe welding process. The welding seam is made by melting the base metal of the steel strip body, and the mechanical strength is better than that of the ordinary welded pipe. "LSAW steel pipe"is a straight seam submerged arc welded steel pipe. Its main technical characteristics are as follows:1.
Difference between erw and saw steel pipe, Sunny Steel The main products of the SAW steel pipes LSAW Steel Pipe, Longitudinally Submerged Arc Welding Steel Pipe LSAW steel pipe, it is the use of submerged arc welding production of straight seam steel pipe. Difference between erw and saw steel pipe. As ERW steel pipe and SAW steel pipe in the pipe during forming, welding and process is different, so
Dec 31, 2020 · Straight seam steel pipe Straight seam steel pipe is a steel pipe whose weld is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on. Straight seam welded pipe has simple production process, high production efficiency

Non-destructive Testing of ERW Straight Seam Steel PipeJun 29, 2020 · Basic requirements for the appearance of ERW straight seam steel pipe welds Before the non-destructive testing of straight seam steel pipes(ERW pipe), the appearance inspection of welds should meet the requirements. The general requirements for the appearance of straight seam steel pipe welds and the surface quality of welded joints are as follows:
Types of Oil & Gas Pipes:Seamless, ERW, LSAW Dec 20, 2018 · ERW pipes are manufactured using steel coils:the coil is first uncoiled, then smoothed, cut, and, finally formed into a pipe shape by joining its two extremities electrically. ERW pipes are available in sizes between 1/2 and 20 inches, in carbon steel (ASTM A53 is the most common specification) and stainless steel (ASTM A312).
ERW Steel Pipe:high-frequency straight seam resistance welded pipe, which uses hot-rolled wide coils as raw materials and undergoes pre-bending, continuous forming, welding, heat treatment, sizing, straightening, and cutting.It has the advantages of high dimensional accuracy, uniform wall thickness, good surface quality, and high pressure resistance, but the disadvantage is that it can only
