GRP Jacking
SUPERLIT’s newly developed GRP Jacking Couplings are designed as an alternative solution to steel couplings used in trenchless applications, offering corrosion resistance.
In aggressive soil environments where the service life of metal couplings is limited due to corrosion, the GRP composite structure provides a long-lasting and durable solution. These innovative GRP Jacking Couplings offer a service life of at least 50 years in similar and even higher corrosive conditions. They provide excellent sealing with a specially designed full-face (Full-Face®) EPDM gasket profile and fully comply with the performance requirements of the ISO 25780 standard. SUPERLIT GRP Jacking Couplings are ideal for those seeking a reliable, long-lasting, and corrosion-resistant solution.
SUPERLIT GRP Jacking Couplings are designed to offer superior performance and durability in trenchless applications. The design table on this page provides detailed technical specifications of GRP Jacking Couplings across different diameter and pressure classes. This table, prepared in accordance with the ISO 25780 standard, will help you select the most suitable coupling for your engineering projects. With its corrosion-resistant GRP structure and specially designed full-face (Full-Face®) EPDM gasket profile, SUPERLIT GRP Jacking Couplings offer a long-lasting and reliable solution, delivering superior performance in even the most challenging conditions.
