Types of Oil & Gas PipesSeamless, ERW, LSAW

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).
