Product SystemsGRE pipeline SYSTEMS are made from glass fibers, which are impregnated with an aromatic- or cyclo-aliphatic amine cured epoxy thermoset resin system offers superior corrosion resistance together with excellent mechanical, physical and thermal glass fiber reinforced epoxy pipeline is resistant to the corrosive effects of mixtures with low concentrations of acids, neutral or nearly neutral salts, solvents and caustic substances, both under internal and external reinforced resin rich liner can protect the helical wound continuous glass fibers of the reinforced wall of the pipes and the structural reinforcement of the fittings pipe fabrication processGRE pipes are manufactured using the filament winding method.

9 In this mechanical process, continuous glass fiber rovings are impregnated with epoxy production of GRE pipe starts with the preparation of a steel mandrel, which may be provided with a socket mould. The dimensions of these tools determine the inner dimensions of the pipe and joint fibers are guided through a resin bath, which is filled with epoxy resin and are wound under constant tension in a specific pattern around the polished process continues until the required wall thickness is reached. Generally, the higher the pressure class, the greater the wall thickness of the product will winding process ends with curing the epoxy resin in an oven, extraction of the mandrel/mould from the product, finishing the product by cutting to length and machining the products are subjected to visual and dimensional controls, as well as a hydro test Filament winding processFig.

Cathodic protection is not required. Low weight/easy to install The specific weight of GRE is only 25 % of steel; due to the low weight, GRE pipeline components are easier to handle without using heavy (lifting) equipment. No initial painting or conservation The epoxy topcoat on the outer surface of GRE pipe components is, under normal conditions, resistant to the influences of the INSTALLATION environment and an additional external conservation is initially not DisadvantagesAttention should be paid to the following disadvantages of GRE when comparing with conventional pipe SYSTEMS , such as: Impact resistance The pipe system is more susceptible to impact damage due to the brittle nature of the thermoset resin system.
