Carbon-fiber composite pipeline repair and reinforcement technology has been deployed on many municipal gas pipelines with strong technical and economic results. Our high-strength bidirectional carbon-fiber cloth and epoxy resin composite delivers high specific strength and modulus — minimal added weight, thin section after repair.
The repair system is highly tailorable, bonds tightly to complex surfaces, and preserves the original profile. It increases defect stiffness and strength and reduces stress concentration — avoiding shutdown losses and keeping production safe.
Carbon Fiber as a Reinforcement Material
Carbon fiber is a high-tech material widely used in high-pressure pipes, pressure vessels and structural reinforcement (bridges, power plants, water projects, heritage structures). Its tensile strength exceeds 3500 MPa, well above steel and glass fiber. Its elastic modulus, 230 × 10³ MPa, is very close to steel's 207 × 10³ MPa, and its thermal expansion coefficient is similar. Applied to pipework, it deforms in sync with the host pipe and takes the internal pressure at the defect.
Service Scope
- Pipework: pressure pipes, power cooling water lines, oil and gas lines
- Vessels: storage tanks, pressure tanks
- Steel structures: power towers, structural members
Handles leaks, cracks, weld defects, corrosion, excavation damage, wall thinning, vertical riser repair on platforms — surface or local repair, even full-section pressure uprating. Delivers strength reinforcement, fatigue repair and buckling repair.
