Fiber composite pipeline repair and reinforcement is fast and simple to install — meeting design requirements quickly, with flexibility for all defect types.
1. Data Collection and Design
Follow ISO 24817 or ASME PCC-2. Before repair, collect:
- Pipe OD
- Wall thickness
- Steel grade
- Operating pressure
- Design pressure
- Operating temperature
- Coating type
- Pipe location
- Defect type and dimensions
Use standard-compliant design software to calculate ply count and wrap length for the required repair pressure.
2. Surface Preparation
Strip the coating in the repair zone. Grit-blast or power-tool clean to St3. Solvent-wipe and let the surface dry fully.
3. Defect Levelling
Apply repair compound to level corrosion pits, dents and other discontinuities. Tack-cure before the wrap stage.
4. Fiber Wrap
Impregnate the cloth (Kevlar aramid or carbon fiber, depending on specification) with the matched epoxy. Wrap circumferentially per the design ply count. Roll along the fiber direction to expel air between layers.
5. Cure
Ambient-temperature cure typically 12–24 hours, depending on resin. For elevated-temperature service lines, use the matched high-temperature resin and follow the post-cure schedule.
6. Inspection and Back-Fill
Visual inspection for surface defects, plus hardness check on the cured composite. Apply outer corrosion protection. Back-fill the pipe trench.
