Key Industry Challenges
Petrochemical pipelines transport a variety of media with great differences in properties (such as crude oil, finished oil, chemical raw materials, etc.). The working temperature and pressure fluctuate greatly, which places high requirements on material c
Medium Compatibility and Corrosion Issues
Different media (especially sulfur-containing and chlorine-containing media) cause various types of corrosion to pipeline materials. Traditional materials are prone to pitting corrosion and stress corrosion cracking.
Risks of High Temperature, High Pressure and Seal Failure
Pipelines of high-pressure hydrogenation, cracking and other equipment have high pressure and temperature. Sealing failure is likely to occur at the connections of flanges, valves, etc., leading to leakage accidents.

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.
