GRP couplings offer the opportunity to make quick, simple, and safe connections in every ground and weather conditions compared to the alternatives.
When Subor GRP pipes are mounted, they are joined to each other via joint systems with REKA type GRP couplings that ensure absolute sealing. GRP couplings produced with the technique used in GRP pipes are prepared at the cutting and grooving machines and then are subjected to leakage tests under pressure. Sealing in couplings are ensured with gaskets from elastomeric materials. This property of the gaskets allow certain angular deviations of the couplings and prevent the reflection of stresses encountered in ground subsidence and earth movements such as earthquakes directly on the pipes. REKA type Full sealing is ensured via sleeve connections with gaskets. It is expandable. It was successfully applied at earthquake sites.
