- Product Description
-
Product Overview
Huayang large bore API 5L LSAW steel pipe, engineered for energy transmission and major infrastructure construction projects.Parameter Specification Material Grade API 5L Gr.B / X52 / X65 / X70 Manufacturing LSAW Submerged Arc Welding Diameter Range 508–1422 mm Wall Thickness 8–40 mm Application Energy and infrastructure construction This large-diameter steel pipe delivers high structural strength, excellent weld quality, and efficient long-distance transmission capability.
Material Performance & Application
Huayang API 5L large bore LSAW steel pipes are manufactured from premium steel plates using advanced longitudinal submerged arc welding technology, ensuring deep weld penetration, high dimensional accuracy, and outstanding seam integrity. Available in grades such as X52, X65, and X70, these pipes offer excellent yield strength, fracture toughness, and resistance to mechanical stress, making them suitable for oil and gas transmission, water supply networks, hydropower projects, and large-scale infrastructure developments. The large bore design significantly increases flow capacity while maintaining stable pressure performance. Every pipe undergoes ultrasonic testing, X-ray weld inspection, hydrostatic pressure testing, and comprehensive mechanical property evaluation to ensure compliance with international pipeline and infrastructure standards.
