The ASTM A672 Grade C60/C70 Class 2 LSAW steel pipe is designed for long-distance oil transportation under medium to high pressure conditions. The diameter range from 508 mm to 1219.2 mm covers both trunk lines and branch pipelines, while wall thickness up to 22.23 mm ensures excellent pressure-bearing capacity and structural stability for buried and above-ground oil pipelines.
Huayang Manufacturing Capability and Oil Pipeline Application
Huayang Steel Pipe has long specialized in the mass production of LSAW longitudinal submerged arc welded gas pipelines, covering outside diameters from 406 mm to 1422 mm and wall thicknesses from 7 mm to 50 mm. This production range fully meets the requirements of common gas pipeline specifications such as 530×8 and 406.4×9.5.
The pipes are manufactured using the JCOE forming process with internal and external double-sided submerged arc welding. Each weld seam is subjected to ultrasonic testing, X-ray inspection, and hydrostatic pressure testing to ensure uniform strength and consistent weld quality.
For gas transmission service conditions, Huayang can provide complete coating solutions, including 3PE external anti-corrosion coating and internal liquid epoxy lining, suitable for buried, long-distance, and above-ground pipeline installations. These pipelines have been successfully applied in multiple domestic urban gas trunk networks and regional energy transmission projects, demonstrating long-term sealing reliability and structural stability in continuous operation.
