API 5L PSL1 pipes with 3LPE coating manufactured by Haihao Group
API 5L PSL1 Pipe for Long-Term Corrosion Protection
The API 5L PSL1 pipe supplied in this order is designed for pipeline systems that require excellent mechanical strength and long-term corrosion resistance. The seamless construction provides superior structural integrity, while the 3LPE external coating significantly improves protection against moisture, soil corrosion, and harsh environmental conditions.
The combination of API 5L PSL1 pipe, bevel ends, and UV-resistant coating makes these products suitable for underground transmission lines, oil gathering systems, and cross-country pipeline projects.
ASTM A106 Grade B Seamless Pipes for High-Pressure Service
The shipment also includes seamless ASTM A106 Grade B pipes manufactured according to ASME B36.10. These pipes feature SCH XXS wall thickness, providing enhanced pressure-bearing capability for critical industrial services.
Each API 5L PSL1 pipe and ASTM A106 pipe was manufactured with strict dimensional control and subjected to comprehensive inspections to ensure reliable field performance.
NACE MR0175 Compliance for Sour Service Applications
Some products in this shipment comply with NACE MR0175, an important requirement for equipment operating in sour environments containing hydrogen sulfide (H₂S).
By meeting this specification, Haihao Group helps customers reduce the risk of sulfide stress cracking while extending the service life of pipeline systems used in oilfields, refineries, and natural gas facilities.
The inclusion of API 5L PSL1 pipe with NACE-compliant materials further enhances reliability for demanding energy projects in the Middle East.
