The API 5L Gr.B PSL1 LSAW steel pipe is widely used in long-distance natural gas transmission systems. With an outside diameter range from 114.3 mm to 1422 mm, this product covers both branch lines and main trunk pipelines. Gr.B material provides stable yield strength and good weldability, ensuring safe operation under internal pressure. The LSAW process guarantees straightness, roundness, and uniform wall thickness for large-diameter pipeline construction.
Huayang LSAW Production for Gas Transmission Projects
Huayang Steel Pipe specializes in large-diameter LSAW pipeline manufacturing, with production capacity from 406.4 mm to 1422.4 mm and wall thickness from 7 mm up to 50 mm. All API 5L PSL1 pipes are produced using JCO forming and double-sided submerged arc welding for consistent weld quality.
Each pipe is subjected to ultrasonic testing, X-ray inspection, hydrostatic pressure testing, and mechanical property verification. For natural gas service, Huayang also provides internal epoxy lining and external 3LPE anti-corrosion coating to meet long-term pipeline operation requirements.
