Glass fibre pipes, flanges and fittings in glass fibre reinforced vinylester - GRV - and glass fibre reinforced epoxy – GRE.
GRP FRP Pipes are widely used in various applications from drainage to sewerage and potable water. Typically available in a Vinylester or Epoxy resin, GRP FRP tubes are favoured for a number of reasons. Lightweight pipes make it easier (and cheaper!) to transport, handle and install. The pipes also have a high level of corrosion resistance from both the external environment and the internal flow. They also have a lower density, lower thermal expansion factor and a high strength to weight ratio.
Elemy can supply various types of composite pipes DN 25 – DN 400 mm with Vinylester or Epoxy matrix and various pressure ratings and jointing configurations.
• All pipes are plain end.
• Pipes are supplied with an inner corrosion barrier 0.5mm – 2.5mm.
• Large diameters available on request.
Resin Transfer Moulding is a resin injection process consisting of five phases. The RTM process consists of five phases; placement of reinforcement, mould closure, resin injection, resin curing, and finally; demoulding. The process is automated to a maximum extent and therefore has significant advantages over alternative production methods such as hand lay-up or spray-up. These advantages include:
High pressure flanges for large diameters also available.
Stub flange, fixed flange, blind flange and backing ring all available.
GRP FRP Backing Rings by Resin Transfer Moulding and Hot Pressing offer an excellent competitive solution to stainless steel, with very high and constant quality.
Glass fibre Reinforced Vinylester (GRV) Backing Rings made by Resin Transfer Molding (RTM) and Compression moulding (CM/SMC) are corrosion free, high performance products, suitable for both Thermoplastic and Thermoset pipe systems. The RTM and CM/SMC manufacturing technology are closed mould manufacturing methods, ensuring high fibre content and high performance laminates, capable to handle high mechanical loads.
Composite Backing Rings are a very good and competitive alternative for Stainless Steel alloys (SS 304 / SS 316 / Duplex), are light weight compared to steel and easy to handle. The Backing Rings have a specific inner diameter to meet the dimensions of PE, PP, PVC and GRP stub flanges of the pipe system.
Specifications of Composite Backing Rings:
The allowable operating temperature can be increased to 110°C. if required (at cost).
The inside diameter of Backing Rings can be modified as per customers’ requirements.
All flanges available with drillings according to different Standards: EN 1092 / ASA / ANSI / JIS / AWWA / AS 4087
The unique combination of materials and production method guarantees excellent constant quality.
