Crack Repair of Pressure Vessels with Carbon Fiber Composite

Unlike conventional weld-patch or steel-patch methods, vacuum-assisted, hot-work-free composite repair bonds carbon fiber cloth directly over the defect to stop leaks and reinforce — with a thermal expansion coefficient closely matched to steel and long service life.

Carbon-Fiber Reinforcement of Gas Pipelines

For medium-to-high-pressure gas lines, welding is hazardous, replacement is expensive, and clamps are complex. Carbon-fiber composite repair enables hot-work-free, live-pressure reinforcement with no service interruption — the modern standard of care.

Defects and Repair of Crude-Oil Pipelines

The main risks to oil pipelines are third-party damage and coating-failure corrosion. For mechanically damaged or corroded sections, carbon-fiber composite repair — hot-work-free and live-pressure — has been validated in field jobs such as the Western Pipeline Wulan repair.
