GRP pipes produced with Continuous Filament Winding (CFW) are commonly joined using two methods:

1. Laminated Joints

This method involves bonding fiberglass layers at the pipe ends, creating a strong, seamless, and corrosion-resistant connection. It’s ideal for high-pressure applications.

2. Pipe-Coupling Types

• Reka Gasket Coupling

The system is engineered to provide a strong, durable, and leak-proof connection between pipe sections, ensuring optimal performance in high-pressure and corrosive environments.

• The sealing includes elastomeric sealing rings, often made from EPDM, which provide a watertight and pressure-resistant seal.
• The sealing rings are seated in grooves to prevent displacement during installation or operation.

• Full-Face Gasket Coupling

The Full-Face Gasket for GRP is a critical sealing component designed specifically for Glass Reinforced Plastic (GRP) piping systems. It ensures a reliable, leak-proof connection in flanged joints, making it suitable for applications in water supply, wastewater, and industrial systems.

• The EPDM rubber gasket is bonded with the coupling in the factory, under controlled conditions;
• The coupling is produced with full-glass system (without silica sand);
• The coupling does not have to be machined internally to create grooves;
• Hydrostatic testing of the finished coupling is not required;
• The stopper covers whole circumferential internal surface;
• The pipe joint performance increases under higher pressure, due to special rubber profile.
