LSAW steel pipe, hot-rolled or cold-rolled steel sheet or steel coil made of steel pipe welding equipment in the straight seam welding are called the straight seam welded pipe. It is cut into strips by a steel strip, and then wrapped into a tubular cold mold. Then a special welder and then a seam welded. Outer weld brightly polished.

Double Submerged Arc Welded (DSAW) steel pipe is available in straight and spiral welded formats and used in a variety of applications. The submerged welding process protects the steel from contamination of impurities in the air. Both inside and outside welds are performed.
DSAW Pipe. Double Submerged Arc Welded pipe (DSAW) if cold formed from a single piece of steel plate by rolling or pressing. The longitudinal seam is welded both inside and outside using the submerged arc welding process. Each piece is often cold expanded to meet tight dimensional tolerance.
API LSAW Pipe Manufacturing Process. 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.
Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).
Seamless steel pipes are mainly used in oil pipeline and gas pipeline, but seldom used in oil pipelines with long-distance. Most long distance pipeline applied ERW pipes, SSAW pipes and LSAW pipes. Here are comparisons of technological features and performance of these pipes.

Dec 20, 2018 · 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. The difference between LSAW and ERW pipes is that LSAW pipes are produced using steel plates, ERW pipes are manufactured starting from steel coils.
