Difference in ERW and SAWL - Guangdong Lizz Steel Pipe

Longitudinal submerged arc welding (SAWL steel) because it uses the welding cold expanding process pipe, so the SAWL pipe dimension precision, using SAWL steel pipe butt counterparts in good quality so as to ensure the welding quality, through expanding technology to some extent by removing a portion of the internal stress. LSAW Pipe Manufacturing Process - Threeway SteelAn LSAW pipe (submerged arc welding) is manufactured by cutting, bending and welding steel plates (JCOE process). LSAW pipes compete with seamless and ERW pipes in the size range between 16 and 24 inches but are must-go option for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).

LSAW Steel Pipe ASTM 53API 5L - Threeway Steel Co., Ltd

Product introduction:LSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production. Longitudinal Submerged-Arc Welded Steel Pipe Process:LSAW UO (UOE), RB (RBE), JCO (JCOE,COE) DSAW -Double Submerged arc welded. LSAW Steel Pipe,SAWL Steel Pipe Manufacturers, LSAW pipe These LSAW pipe material is carbon steel and has other name called SAWL pipe, DSAW steel pipe, Straight seam welded pipe, Longitudinal submerged arc welding pipe, straight line welding pipe, EFW steel pipe, EFW welded pipe. LSAW pipe, DSAW pipe, longitudinal welded pipe - steel LSAW pipe, DSAW pipe, longitudinal welded pipe, LSAW(longitudinal Submerged Arc Welding) pipe is fromed by JCOE with one straight welded seam, the outer diameters usually from 323mm to 1420mm. When the outer diameter is 914.4mm above, it's allowed two straight welded seams.

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, Longitudinal Submerged Arc Welding (LSAW,SAWL, DSAW)steel pipe OD:406m API 5L - ALD Products Made In China, China Manufacturer. Longitudinal Submerged Arc Welding (LSAW,SAWL, Longitudinal Submerged Arc Welding (LSAW,SAWL, DSAW)steel pipe OD:406m. Epoxy black coating, bitumen coating, FBE, 3PE, 3PP, thermal insulation coated.
