L245 and L360 LSAW pipes are commonly selected for gas pipelines where different pressure classes require flexible grade matching and reliable welding quality.
Material Characteristics & Huayang Production Control
L245 and L360 are line pipe grades designed for gas transmission systems under GB/T 9711. L245 provides a minimum yield strength of about 245 MPa, suitable for lower-pressure sections, while L360 offers around 360 MPa yield strength for higher-pressure zones. The sizes 530×8 mm and 406.4×9.5 mm are frequently used in urban trunk lines and regional gas networks. Huayang Steel Pipe manufactures these pipes using qualified steel plates, controlled forming, and double-sided submerged arc welding to ensure uniform weld penetration. Each pipe undergoes ultrasonic weld inspection, hydrostatic pressure testing, and dimensional checks, ensuring stable mechanical performance and long-term safety in gas pipeline service.
