The two main types of LSAW pipes are the longitudinal (with a single or double straight seam weld, DSAW) and the spiral type (called, HSAW, SSAW or SAWL pipe). Therefore, the difference between DSAW vs. LSAW is that DSAW pipes have a seam weld in the inside and outside of the pipe, whereas LSAW pipes have a single seam weld on the outer surface.
HSAW LSAW and HSAW are variants of SAW (submerged arc welded) pipes. The difference between them is the way they are welded. In LSAW pipes, the welding is longitudinal, which means that steel (hot rolled coil plate) is rolled into a pipe and the seam is welded longitudinally.
LSAW Steel Pipe. Pipe TypeLongitudinal Welded Pipe, Longitudinal Submerged Arc Welded Pipe. ApplicationUsed for Fluids Transmission, Structural Support in Industrial Construction. SpecificationOD406mm ~ 1422 mm.
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.
Both the seams are welded from inside and outside of the pipe. In the case of high thickness pipe, multiple pass welding is done. In a spiral saw pipe, steel plate from the de coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe.
HYSP as the professional ERW steel pipe manufacuturer, is pleased to share the erw steel pipe or other kind of steel pipe knowledge to everyone who needs it. Let’s see the difference between LSAW pipes and ERW steel pipe1, the production process High frequency welding straight seam steel pipe (ERW) production process is simple, a 
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.
