Key Features & Advantages

High Strength & Pressure Bearing Capacity: X60M grade provides superior yield and tensile strength, suitable for medium-to-high pressure oil and gas transmission pipelines.

Strict PSL2 Quality Standard: Compared to PSL1, PSL2 requires more rigorous inspection and testing, ensuring higher reliability and consistency in product quality.

Excellent Weldability: Optimized chemical composition and CEV control enable easy field and shop welding, reducing construction time and cost.

Superior Toughness: Mandatory low-temperature impact test ensures the pipe can withstand extreme temperature changes and ground movement without cracking.

Corrosion Resistance: Optional FBE/3PE coating provides long-term protection against soil, water, and chemical corrosion, extending service life.

Full Traceability: Each pipe is traceable from raw material to finished product, with complete test reports and certificates.

Typical Applications

Long-distance onshore and offshore oil & natural gas transmission pipelines

Oil and gas gathering pipelines in oilfields and gas fields

Medium-to-high pressure industrial fluid transportation (e.g., slurry, chemicals)

Energy pipeline projects requiring PSL2 quality and X60M strength level

Municipal and industrial high-pressure water supply pipelines

Inspection & Testing (PSL2 Mandatory Requirements)

Chemical Analysis: Spectrometer test for heat analysis and product analysis to verify chemical composition compliance.

Mechanical Tests: Tensile test, flattening test, flaring test, and bending test to confirm mechanical properties.

Impact Test: Charpy V-notch impact test at specified temperature (mandatory for PSL2) to ensure toughness.

Non-Destructive Testing (NDT):

Hydrostatic Pressure Test: 1.5 times the nominal pressure, held for a specified time to ensure leak-proof performance.

Ultrasonic Test (UT): For weld and seamless pipe inspection to detect internal defects.

Eddy Current Test (ET): For surface defect inspection of welded pipes.

Dimensional & Visual Inspection: Verification of OD, WT, length, end preparation, and surface quality.

Packaging & Marking
