Juneng carbon-fiber composite pipe repair technology has been deployed across many municipal gas company pipelines, with strong technical and economic results.
Our high-strength bidirectional carbon-fiber cloth and epoxy resin composite delivers minimal added weight and a thin section after install. The system is highly tailorable: it bonds tightly to complex surfaces, preserves the original pipe profile, raises defect-zone stiffness and strength, reduces stress concentration — avoiding shutdown losses and keeping production safe.
Method Principles
Fiber composite repair uses filler resin to level defects, then a dedicated adhesive bonds fiber cloth circumferentially to form the composite layer. After cure, the layer is integral with the pipe and carries internal pressure on behalf of the lost wall — restoring design pressure.
Service Scope
- Long-haul oil and gas pipelines
