The inner surface of SUPERLIT GRP Full Face Couplings® is completely covered with EPDM seals, providing safer joint tightness compared to similar systems; guaranteeing water-tightness under high pressure. Since the seal is integrated into the coupling, it does not dislocate. There is no need for installation on-site. SUPERLIT GRP pipes produced by centrifugal casting and continuous filament winding methods have the same external diameters for the same nominal diameter. Therefore, regardless of the manufacturing method, the same SUPERLIT GRP Full Face Coupling® can be used on pipes with the same nominal diameter.

The special Marine Lug®, designed and patented by SUPERLIT engineers for the installation of large diameter pipes underwater, is an underwater pipe laying system. It facilitates the assembly of pipes underwater, keeping them stable until backfilling is completed. - Steel-bodied lug rings - Rotatable (easily fits into the lug slots) - Removable after pipe installation - Fast and easy production and assembly capabilities The rapid and easy installation of the newly designed Marine Lug® systems is an important criterion for divers who can only stay underwater for a limited period. With the Marine Lug® systems, divers can quickly complete the pipe laying process without taking life-threatening risks, while companies achieve high efficiency at lower costs.

Developed as a result of Superlit's R&D studies, the SUPERLIT GRP Full Face Slip-On Coupling® offers a solution to technical problems such as repairing damaged pipelines and closing assembly gaps with its profile design that allows movement in both directions over the pipe. This is achieved using corrosion-resistant GRP composite material. The inner surface of SUPERLIT GRP Full Face Slip-On Couplings® is completely covered with an integrated EPDM seal. The new GRP (Glassfiber Reinforced Polyester) Slip-On Coupling, which meets all the performance criteria outlined in international standards (angular deflection, pressure, external load, and vacuum), can be slid over the pipe along its entire body.

SUPERLIT's YouTube video details the processes of GRP (Glass Reinforced Polyester) pipes from shipping to installation in a pipeline. The video takes viewers step by step through the production of the pipes in the factory, their transportation, on-site storage, trench excavation, and pipe installation. It also emphasizes the safety measures and quality controls that must be observed during installation. While providing information about the technologies and equipment used, the video also highlights the superior features and advantages of GRP pipes.

Founded in 1961 as the first company of KARAMANCI HOLDING, SUPERLIT is a leading global manufacturer of GRP (Glassfiber Reinforced Polyester) pipes for various applications. Producing pipes with diameters ranging from DN300 mm to DN4000 mm at its Düzce and Malatya (Turkey) plants, SUPERLIT offers high strength and pressure resistance. The company utilizes Continuous Filament Winding, Centrifugal Casting, and Helical Winding technologies. SUPERLIT holds ISO 9001, ISO 14001, and ISO 45001 certifications and provides products and technical services to more than 70 countries across five continents.

Jacking and re-lining methods improve infrastructure quality without disrupting urban life and traffic flow. SUPERLIT pipes offer excellent solutions with trenchless technology for renewing worn-out pipelines. Re-lining pipes are placed inside pre-existing pipelines, while the jacking method involves placing pipes underground using specialized machinery. These methods offer advantages such as lower jacking forces and costs, easy installation, minimal excavation, angular deflection capability, reduced environmental impact, applicability in adverse weather conditions, no need for water level intervention, no large storage area requirement, and minimal noise and pollution. SUPERLIT's trenchless technologies make infrastructure projects fast, economical, and environmentally friendly, making them ideal for new projects and renovation works.
