Material Grade: API 5L X46
Yield Strength: The "X46" designation indicates a minimum yield strength of 46 ksi (317 MPa). This grade provides superior load-bearing capacity compared to standard Grade B pipes, making it suitable for more demanding transmission environments.
Chemical Composition: Manufactured from low-carbon micro-alloyed steel, ensuring excellent toughness and resistance to brittle fracture.
Quality Levels: Available in both PSL1 (Product Specification Level 1) and PSL2 (Product Specification Level 2), with PSL2 offering stricter requirements for chemical composition, impact testing, and non-destructive testing.
HFW / ERW manufacturing
High-Frequency Welding: Utilizes advanced high-frequency electric resistance welding technology. The heat generated by the resistance of the current fuses the edges of the steel strip without filler metal, creating a homogeneous and robust weld seam.
Precision & Uniformity: ERW pipes feature excellent dimensional accuracy, uniform wall thickness, and a smooth surface finish. The weld seam is often heat-treated to normalize the microstructure, ensuring mechanical properties comparable to seamless pipes in many applications.
Efficiency: The continuous production process allows for high manufacturing efficiency and consistent quality control.
