What is The Differences Between LSAW Pipe and SSAW

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing. LSAW/ JCOE Welding Steel Pipe - SENHAI PIPELINEJun 20, 2013 · Product profile :LSAW/ JCOE Welding Steel Pipe. Welding Technology :1)LSAW-Longitudinal Submerged-arc Welded Steel Pipes / tubes 2)JCOE Welded Steel Pipes Out Diameter:ERW 21.3mm~168mm ; LSAW 219mm~1422.4mm Wall Thickness:2.5mm~100mm Length:2m~12m Material:API 5L GR B, ASTM A106 GR A/B/C,ASTM A53 GR A/B, A210, A252, SSAW Steel Pipe vs. LSAW Steel Pipe - ESC GroupAug 06, 2021 · SSAW Steel Pipe. LSAW and SSAW employ the same manufacturing technology JCOE process. The difference is SSAW pipes are welded in the helix or spiral position while LSAW pipes are welded in the longitudinal direction. Manufacturing process of SSAW pipe is by rolling and welding a steel strip in a way that the pivotal direction is oblique to Difference between ERW, HFW, SAW and EFW pipe www Jun 03, 2021 · An 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 options for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes). LSAW Pipe / JCOE Pipe - Hebei All Land Steel PipeLSAW Pipe / JCOE Pipe. LSAW pipe also called JCOE pipe, LSAW is for Longitudinal double submerge arc welding process, it is a type of SAW pipe made of steel plates that were hot rolled by JCOE or UOE forming technology. JCOE technology means the forming processes covering J-Shape, C-Shape, O-Shape and E-Expanding. Hebei All Land equiped with Forming Process of LSAW Steel Pipe (UOE vs JCOE)Dec 01, 2020 · The steel plate is formed in the order of J type-C type-O type, and the diameter is expanded to JCOE welded pipe after welding, or it is not expanded to JCO welded pipe. UOE LSAW pipe forming process:The three main forming processes of UOE LSAW steel pipe forming process include:steel plate pre-bending, U forming and O forming. Each process Differences Between ERW and LSAW Steel PipeSep 23, 2020 · JCOE steel pipe:according to "J-C-O-E" pre-welding, forming, and cold expanding after welding HME steel pipe:It is formed by mandrel rolling method according to "C-C-O", welded and then cold-expanded. 2. The difference in welding ERW steel pipe welding does not need to add welding wire; LSAW steel pipe requires welding wire. 3. LSAW Steel Pipe Production Line JianHe SteelJianhe Steel has a state-of-the-art production line for LSAW steel pipes. This line uses a YSD forming machine that features a high forming precision, excellent forming speed, uniform stress distribution and small residual stress. The main equipment, such as the pre-springing equipment, is supplied by the Tianshui Metalforming Machine Tool Group. LSAW PIPE - Piping System SolutionsAug 17, 2021 · The advantages of LSAW (Longitudinal Submerged Arc Welding) pipes are straight welding. They are widely used in heavy industry to convey oil, coal slurry, etc. As a ISO 9001:2008 company, we guarantee not only quality but also services. Process:LSAW - UO (UOE), RB (RBE), JCO (JCOE, COE); DSAW - Double Submerged Arc Welded.
