Using completely automated systems, GYPSUM COMPOSITES INTERNATIONAL manufactures glass-fiber reinforced plastic pipes by a filament winding process for application in various water and wastewater network systems. Our core competency is in manufacturing of egg and special shaped profiles – the GCI GRP Structural Liner – with a length of up to 6 meter and a diameter ranging from DN 400 up to DN 3,200 mm.
APPLICATION OF GRP PIPES
Water and waste water pipes
Water and waste water pipe rehabilitation (insertion of GRP pipes into host pipes)
Industrial pipes – chemical and petro chemical
GRP MANUFACTURING SETUP
Our GRP pipes are manufactured in a continuous serial production on winding machines where mandrel rotation and material flow acceleration / deceleration for tangents in non-circular shapes can be set using complex software.
This manufacturing process is based on a fiber reinforced polymer made of a plastic matrix, reinforced by fine fibers of glass and with admixture of fillers (silica), forming a thermosetting composite matrix. With this dual system, the advantages of the special inner resin rich layer for corrosive applications can be realized while using standard resin, fiber, glass and silica for perfect structural properties. Especially developed calculation tools for the design of the GRP pipes enable customer-tailored solutions.
Major raw materials used are isophtalic and orthophtalic resin, silica sand and glass fibers, supplemented by additives and catalysts. The material components are brought up in layers, applied following a program-controlled process, thereby, providing high standards and repeatable quality in GRP pipes. Each layer as well as the whole structure has an exactly defined composition.
