Composite reinforcement performance on pressure piping depends on the composite's tensile strength and elastic modulus. Carbon fiber is a high-tech material widely used in high-pressure pipes, pressure vessels and structural reinforcement (bridges, power plants, water projects, heritage), with very high tensile strength and modulus.
Carbon-fiber tensile strength exceeds 3500 MPa, well above steel and glass fiber. Composite modulus is nearly identical to steel's 207 × 10³ MPa, so the reinforcement and the steel pipe deform compatibly. The composite layer carries internal pressure at the defect.
Seven Technical Advantages
- Hot-work-free, repair under live pressure
- Simple and fast installation
- Modulus close to steel — composite shares load and constrains expansion
- High tensile strength, excellent creep resistance — stable performance over service life
- Thin section — friendly to subsequent corrosion protection
- Flexible wrap geometry — fits girth welds, spiral welds, elbows, tees, reducers and irregular fittings
- Broad scope — corrosion, mechanical damage, cracks; also full-section pressure uprating
