Pipeline Integrity
Permanent Non-Metallic Sleeve (Strongpipe)
Our repair technology offers complete structural repair and reinforcement solutions that are safe, flexible, practical, and cost-effective. This unique composite system consists of layers of reinforcing steel wire and fiber-reinforced polymer.
The system provides mechanical and anticorrosive protection using vacuum-impregnated Class S fiberglass reinforced bands.
The system is a high-performance, high-quality non-metallic sleeve.
- Excellent adhesion and impermeability.
- Hardness resistance of up to 120 Shore.
- High-temperature resistance of up to 95°C (203°F).
- Wide flexibility range.
- Resistant to high pressures.
