Key Industry Challenges
Natural gas pipeline systems span the entire length from the source to the end user, facing multiple challenges such as complex operating conditions, high safety risks, and stringent compliance requirements.
Significant risk of corrosion
Natural gas contains extremely high levels of hydrogen sulfide (H₂S) and carbon dioxide (CO₂), which accelerate localized corrosion in buried pipelines under wet gas gathering and transportation conditions, leading to potential hazards such as wall thinning and stress cracking.
Poor adaptability to extreme operating conditions
Long-distance pipelines are often exposed to high-pressure environments with significant temperature fluctuations, and LNG transmission systems must withstand extremely low temperatures of -162°C. Ordinary carbon steel is prone to brittle fracture, making leak detection and repairs extremely difficult.
Key Product Features
Leveraging our specialized materials R&D capabilities and end-to-end quality control system, we have established three core strengths: “safety assurance, operational adaptability, and efficient operation and maintenance.”

High resistance to extreme operating conditions

Balancing security compliance with operational convenience

Case Studies
Natural Gas Pipeline Pressure Upgrade Project
The natural gas pipeline is responsible for gas supply in the northwest region. It utilizes X80-grade alloy steel pipes and A2-grade pressure vessel fittings, and upgrades the manifold and valve systems at seven gas transmission stations to a 4.0 MPa pressure rating. The pipeline employs a fully automated submerged arc welding process, with a 100% pass rate for non-destructive testing of welds.
