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. JCOE technology represents the shaping and forming processes involved during manufacturing as well as the inner and outer welding and cold expansion carried out after welding.

LSAW Pipe stands for Longitudinally Submerged Arc Welding pipe. Pipes manufactured by this process are subjected to expanding operation in order to relieve internal stresses and obtain a perfect dimensional tolerance. Longitudinally welded steel pipes are used in onshore and offshore oil and gas pipelines requiring critical service,

LSAW Pipe (Longitudinal Submerged Arc Welding Pipe), 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 (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.

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 pipe used to convey low pressure liquid meida or high pressure petroleum or natural gas, and can be also used widely in structural supports or foundation.

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 option for pipelines above 24 inches (as 24 inches is the maximum size for commercial seamless pipes).

ERW Welded Steel Pipe Manufacturing MethodWhen the ERW steel pipe welding process, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc shaped and rotate as the material passes between them. This allows the electrodes to stay in constant contact with the material to make long continuous welds.

Longitudinally Submerged Arc Welding (LSAW) pipes use single plate steel as raw material, applied double sided submerged arc welding. The finished products have larger specifications and the welding joints have excellent ductility, plasticity and good sealing.

Only major difference being SSAW pipe is spiral welded whereas 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, forming and welding, so the welding seam is in a spiral line.

LSAW Steel Pipe. Pipe TypeLongitudinal Welded Pipe, Longitudinal Submerged Arc Welded Pipe. ApplicationUsed for Fluids Transmission, Structural Support in Industrial Construction. SpecificationOD406mm ~ 1422 mm.

Utilizes the "JCO" process to bend and form the crimped steel plate into a steel pipe. Interior welding machine The interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged arc welding process. End facing machine
