HFW Pipe DN600 API 5L PSL1: For Onshore Oil Transmission & Gathering Lines

API 5L PSL1 grades such as X52 and X60 are commonly used for oil gathering lines due to their balanced mechanical properties and production efficiency. X52 provides a minimum yield strength of approximately 360 MPa, while X60 reaches about 415 MPa, with tensile strength typically ranging from 460 to 760 MPa. The chemical composition is controlled with carbon generally below 0.22 percent and manganese between 1.20 and 1.60 percent, ensuring good weldability and sufficient toughness for field installation conditions. PSL1 focuses on standard mechanical requirements and basic inspection, making it suitable for non-critical or moderate-pressure pipeline systems.

Huayang Steel Pipe manufactures DN600 HFW pipes using advanced high-frequency welding technology, forming a continuous and uniform longitudinal weld seam with stable metallurgical properties. Precision forming ensures accurate diameter control and consistent wall thickness along the pipe body. Each pipe undergoes weld seam ultrasonic inspection, hydrostatic pressure testing, and dimensional verification. For onshore applications, external coatings such as black painting, FBE, or 3PE can be applied to enhance corrosion resistance and adapt to different soil and environmental conditions.
