Superlit Boru San. A.S products

Although standard lengths are 6 m and 12 m, SUPERLIT GRP pipes can be manufactured with the lengths required, only limited by transportation capabilities. Comprising of thermosetting resin and silica sand reinforced with glass fiber, a GRP pipe is a composite material that has flexible characteristics.

In addition to pipes used for water supply, SUPERLIT also caters for water storage needs with its GRP tank systems. The GRP tank systems have an important place in the preservation of water in healthy ambient conditions thanks to its mechanical, thermal and chemical equipment. Providing a considerable advantage in transportation thanks to its lightness, the GRP tank systems are preferred not only because it requires no additional installation costs, but also because it minimizes the time required for installation.

The inner surfaces of the SUPERLIT full-face® GRP couplings are coated completely by EPDM sealing, which maintains a safer joining tightness when compared with similar systems and ensures water-tightness under high pressure. Since the seal is integrated into the coupling, it does not dislocate and does not require to be installed on the worksite.

SUPERLIT FULL-FACE GRP SLIP-ON Coupling ; Developed product as a result of Superlit R&D studies. New designed gasket profile allows sliding of the coupling on both direction over pipe surface, provides a technical solution to the repair of damaged pipe line section and tie-in problems of pipelines with corrosion free GRP composite structure. SUPERLIT FULL-FACE GRP SLIP-ON Couplings are completely covered from inside with EPDM integrated gasket profile bonded in factory condition.

New developed GRP jacking coupling is taking place as an alternative to steel joints which are used in trenchless applications. It provides unique solutions to corrosion issue of agressive soil environment where metal couplings have limit of service life under corrosion attack. New composite jacking coupling has minimum 50 years of service life in similar and even higher conditions. Special designed full face rubber profile ensures leak tigthness by help of its GRP structure of body and fully comply with the performance requirements of ISO 25780 standard.

There are no excavations in the jacking pipe installation model. Pipes are installed inside a tunnel underground by using special purpose machines (tunnel boring machine – TBM), by jacking method.

The relining model also does not require excavation. In order to renew the old pipelines, new GRP pipes are installed by inserting them inside the existing pipes.

Patented special Marine-Lug, which has been designed by SUPERLIT engineers, is an underwater pipe mounting system for installing large diameter pipes.

Process: The Continuous Filament Winding Process is the manufacturing of GRP pipes from continuously flowing glass fiber by winding it on an automatic machine. The inner and outer walls of the pipe are constructed by pressing glass fiber and resin together, and filling material (sand) is then added. As a result of reinforcing a high ratio of polyester by glass fiber, the inner and outer surfaces of the pipe become extremely robust against chemicals. Since the mid-section of the pipe is highly durable, the required stiffness is obtained, and the resistance against working pressures is obtained throughout the length of the pipe.

By using the latest computer technology involved in GRP pipe manufacturing with SUPERLIT Centrifugal Casting, raw material distribution and raw material consumption are kept under control. Theoretical and actual raw material consumption data are reported by the computer. Following the entry of the class and diameter of the pipe to be manufactured into the computer, all manufacturing steps are controlled by the computer until the pipe comes out of the mold.
