Key Advantages
Global Standard ComplianceFully compliant with API 5L PSL1 international line pipe standard, compatible with mainstream specifications like ASTM A53 Grade B. Meets global engineering procurement and construction requirements. Provides authoritative inspection documents including EN 10204 3.1, satisfying strict access conditions for oil & gas and municipal projects.
Reliable ERW TechnologyAdopts high-frequency resistance welding, ensuring uniform microstructure between weld and base metal with mechanical properties close to parent material. Online heat treatment eliminates welding stress, delivering uniform wall thickness, smooth inner/outer surfaces, excellent air-tightness and structural stability to prevent leakage risks.
Precise Dimensions for Efficient InstallationStrictly controlled dimensional tolerances, with OD, wall thickness and straightness accuracy exceeding industry standards. Facilitates on-site welding and connection, reduces installation deviations, shortens construction period and lowers overall engineering costs.
Balanced Performance for Wide AdaptabilityFeatures excellent toughness, weldability and corrosion resistance, suitable for medium and low-pressure fluid transmission. With anti-corrosion coatings, it ensures long-term stable operation in complex environments like marine and chemical industries, with service life exceeding 50 years.
Cost-Effective & Stable Mass ProductionHigh automation and production efficiency of ERW process balance quality and cost, ideal for large-scale pipeline project procurement. Adequate stock and short customization lead time meet fast project delivery requirements.
