API 5L PSL2 Pipe is a line pipe used to transport extracted oil, gas, water, and other fluids to oil and gas industrial facilities. Line pipe steel encompasses two main categories: seamless steel pipes and welded steel pipes. Currently, the most commonly used welded pipe types in oil pipelines include:
Spiral Submerged Arc Welded (SSAW) Pipe
Longitudinal Submerged Arc Welded (LSAW) Pipe
Electric Resistance Welded (ERW) Pipe
Seamless pipes are typically selected for pipeline diameters below 152 mm.
