HFW Steel Pipe DN600 API 5L X52 PSL1 For Oil & Gas Transmission

API 5L X52 PSL1 is a widely used pipeline steel grade with a minimum yield strength of approximately 360 MPa and tensile strength typically ranging from about 460 to 760 MPa. The chemical composition is controlled with carbon generally limited to around 0.22 percent and manganese content between 1.20 and 1.60 percent, ensuring a good balance of strength, toughness, and weldability. PSL1 specification focuses on standard mechanical requirements and basic inspection levels, making it suitable for medium-pressure transmission systems and general oil and gas infrastructure.

Huayang Steel Pipe manufactures DN600 HFW pipes using advanced high-frequency welding technology, forming a continuous and uniform longitudinal weld seam with stable metallurgical bonding. Precision forming and sizing ensure accurate outer diameter and consistent wall thickness throughout the pipe body. Each pipe undergoes weld seam ultrasonic inspection, hydrostatic pressure testing, and dimensional verification. For oil and gas transmission applications, additional anti-corrosion solutions such as FBE or 3PE coatings can be applied to enhance durability and ensure long-term operational reliability.
