The API 5L PSL1 X56Q-Z35 LSAW steel pipe with 610 mm outside diameter and 25.4 mm wall thickness is designed for offshore oil platform pipeline systems. The X56Q grade provides stable yield strength for high-load structures, while the Z35 requirement ensures excellent resistance to lamellar tearing, making it suitable for welded offshore structures exposed to wave loads and complex stresses.




Huayang Manufacturing Strength for Offshore Pipeline Projects
Huayang Steel Pipe produces LSAW pipes from 406.4 mm to 1422.4 mm in diameter with wall thickness up to 50 mm, fully covering the 610×25.4 mm offshore specification. Pipes are manufactured using JCO forming and double-sided submerged arc welding, ensuring uniform wall thickness and stable roundness.
Each offshore pipe undergoes ultrasonic testing, radiographic inspection, mechanical testing, and hydrostatic pressure testing. For marine environments, Huayang can supply 3LPE or 3LPP external coating and internal epoxy lining to ensure long-term corrosion protection and service reliability.
