The dedicated carbon-fiber pipe-repair system has three core components:
- High-strength dedicated repair compound
- High-strength carbon-resin composite
- Outer protective layer
The composite is wrapped onto the host pipe and cured at ambient temperature in the field.
Nine Technical Advantages
- Hot-work free
- Rapid response
- In-service repair, no shutdown
- Long life — 50-year design life
- High composite performance — high modulus, high strength, high elongation
- Excellent corrosion resistance
- Conforms to any pipe geometry
- Handles any defect type
- Compatible with any piping system
Rapid in-service repair shortens the window to 1–2 hours — much faster than welding. Compared with other methods, no-shutdown repair and relaxed condition requirements deliver clear economic benefits, avoiding the heavy losses of a shutdown.
Typical Project
A power-plant cooling-water loop, threatened with failure from corrosion and impact, was reinforced with carbon-fiber epoxy at the defect zones — restoring strength quickly. The system gives large-diameter lines a fast engineered solution for sustained pressure and service life.
Supply Capability
Juneng Weiye supplies unidirectional and bidirectional carbon-fiber cloth, bidirectional aramid cloth, and epoxy resins for pipeline reinforcement. The pipeline division focuses on pressure-pipe repair for petrochemicals, urban gas, pressure vessels and pressure-pipe manufacturing.
