LSAW Pipes:Longitudinally Submerged Arc Welding PipeLSAW pipes play a major role in oil and gas pipelines with features of high strength, high quality and long distance. According to the standard of American Petroleum Institute (API), the LSAW pipes are the only designated pipes in large scaled oil and gas transportation, especially when the pipelines cross the densely populated urban areas and LSAW Steel Pipe, LSAW Steel Pipe Supplier, JCOE STEEL PIPEDec 16, 2019 · LSAW Steel Pipe. As an LSAW Steel Pipe Supplier, I will introduce to you the different molding methods which can be divided into:UOE steel pipe:After pre-bending a single steel plate, it undergoes U-forming, O-forming, internal welding, external welding,
Straight seam submerged arc welded steel pipe diameter up to 406.4-1422.4mm The steel pipe can be up to 12.2m long and the wall thickness is 6.4-26.4mm at the ×70 steel grade. Main features of LSAW pipe:1) The steel pipe has a longitudinal weld, and the inner and outer welds are welded by a submerged arc welding. SEARCH PRODUCTS - China OCTG, Steel Piling, Steel Pipe Required steel pipe in the construction of high-strength, high toughness, high-quality long-distance oil and gas pipelines, mostly large diameter thick wall LSAW. API standard provisions, in the large-scale oil and gas pipelines, when 1, Class 2 areas through the alpine zone, the bottom of the sea, the city densely populated area, LSAW only The Difference and Use of ERW, LSAW and SSAW Steel Pipe2. The line pipe, which is the wire pipe, is relatively thin. It is indicated by "T" and can only be used as a threading pipe. 3. 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 of the steel strip body
According to the manufacturing process of steel pipe, seamless steel pipe can be divided into (SML), as the main oil gathering pipe and the small caliber high pressure natural gas pipeline, the number for the long oil pipeline is very few, most of the pipeline is the use of high-frequency welded pipes (), spiral submerged arc welding pipe (SSAW) and LSAW (LSAW) three.

ERW (eletrical resistance weld) is a welding method in which pipe is welded without adding filler material.ERW is either high or low frequency.Electric resistance welded steel pipe(ERW steel pipe) is manufactured by cold-forming a sheet of steel plate into a cylindrical shape.ERW has the weld seam on the inside of the pipe. LSAW Steel Pipe Forming MethodLSAW steel pipe (Longitudinally Submerged Arc Welding is abbreviated as LSAW) is a professional eion term for straight seam submerged arc welded steel pipe. LSAW steel pipe is produced by using a single medium-thick plate as a raw material, pressing (rolling) the steel plate into a tube blank in a mold or forming machine, and using double-sided submerged arc welding and expanding the
