LSAW, SSAW, and ERW Pipes Description and Comparison

May 06, 2020 · In the oil and gas industry, large-diameter API 5L LSAW pipes are use d to transport hydrocarbons over long distances efficiently. HSAW (helical submerged arc welding) or SSAW pipe diameter range is generally 20 inch to 100 inch (406mm to 2540mm). One advantage of SSAW is the possibility to obtain different diameter Longitudinal Submerged Arc Welding (LSAW,SAWL, API 5L ALD China, Type:(LSAW,SAWL, DSAW)steel pipe API 5L 45 eddition Line pipes OD:406mm-1930mm Wall thickness 12.7mm-100mm Standard API SPEC 5L PSL1 PSL2 Material X42 X46 X52 X56 X60.

Longitudinal-seam Submerged Arc Welded (LSAW) pipes

Longitudinal-seam Submerged Arc Welded (LSAW) pipes were made of steel plates cut from leveled hot rolled coils by both the JCOE and UOE (the forming process in which the plate like the letter J, C, O or U shape, then expansion) forming processes. Furthermore, the mechanical properties of the pipe base metal and weld metal were tested, and the results were in accordance Longitudinally Submerged Arc Welded Steel pipes, LSAW Longitudinally Submerged Arc Welded Steel pipes LSAW (Longitudinal double submerge arc welding) carbon steel pipe is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology.

Quality Manufacture/Supply spiral seam submerged-arc welded pipe - find quality New product, Steel Pipes & New product from Zhejiang Chankong Steel Pipe Co.Ltd. of China Suppliers - 151352990. The difference between ERW, SSAW and LSAWJan 10, 2018 · The longitudinal submerged arc (LSAW) is a single thick plate as raw materials, the steel plate in the mold or molding machine pressure (volume), using double-sided submerged arc welding and expanding into production. Its finished product specification range is wide. The toughness, plasticity, uniformity and compactness of the weld are good.

Types and process of welding pipe-ERW,LW,CW,SAW pipes

Spiral submerged arc welding (SSAW) steel pipe,also called HSAW pipe,welding line shape like a helix.It is using the same welding technology of Submerged Arc-Welding with LSAW pipe.Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded.Manufacturing process is rolling the steel strip,to make the rolling direction have an angle with the direction of the pipe center longitudinal seam submerged arc welded steel pipeWith seamless welding quality, these longitudinal seam submerged arc welded steel pipe are annealed with nitrogen protection and are polished with utter professionalism. These products are made of robust materials such as carbon steel, stainless steel, galvanized surface-treated iron and many more to offer consistent service for a long time.
