Offshore Engineering Solutions
Key Industry Challenges
Offshore engineering pipelines are in a marine environment with high salt spray, high humidity and severe corrosion for a long time, and at the same time bear complex loads such as waves, ocean currents and typhoons, which places high requirements on mate
Severe corrosion in Marine Environment
Seawater, salt spray and microbial corrosion will quickly erode the outer wall of the pipeline. Even carbon steel is very prone to uniform corrosion and local pitting corrosion.
Complex Loads and Fatigue Damage
Waves, ocean currents and platform vibration will cause alternating loads on the pipeline, which is likely to lead to fatigue cracking at welds and joints after long-term operation.
High Difficulty in Installation and Maintenance
The cost of pipeline installation, inspection and maintenance in deep-sea or offshore environments is extremely high, and the requirements for pipeline reliability and service life are much higher than those of onshore pipelines.
Key Product Features
Through high-performance anti-corrosion coatings, high-strength structural design and anti-fatigue technology, we create long-life offshore engineering pipelines that are resistant to marine corrosion and complex loads.

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.
