LSAW Pipes

LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), DSAW pipe (Double Submerged Arc Welded Steel Pipe), Both of them are made of Steel raw materials by Arc Welding way which take 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.

Applications of LSAW Pipes
It has been widely applied in the oil and gas pipelines, specially which requires large diameter and thick wall pipe with high strength and long distance.

Meanwhile LSAW pipe uses in construction of structure that needs tough strength, water treatment, thermal industry, bridge building, etc. According API specifications, the LSAW pipe is specially designated in large scaled oil and gas transportation, in the cases that pipeline goes across the city, sea, and the urban area. These are the class 1 and class 2 areas.

LSAW Pipes FAQs
What Makes Dsaw Pipes Difference From Other LSAW Pipes?

It's that DSAW has a seam weld in the inside and outside of the pipe, while the LASW has a single seam weld on the outer surface, longitudinal or cross sectional.
