GRP Pipes & Fittings
Fiber Glass Reinforced Plastic Pipe is a matrix or composite of glass fibre such as E-Glass fiber and ECR- Glass Fiber , polyester resin and fillers that the most common filler is fine silica sand . These pipes possess better strength durability high tensile strength low density and are virtually inert.
The glass fibers provide strength and stability, and the fillers contribute to high bending stiffness. With the glass fibers oriented in the desired direction, the fillers strategically placed, and all wetted out with resin and then cured at elevated temperatures, an exceptionally strong and stable laminate is formed.

In case chlorine is added to water , then the polyester resin must be chlorendic resin that can withstand against chlorine corrosion . Diameter range is from 25mm to 4000 mm in diameter , and there are three well know methods to produce glass reinforced plastic pipes :
- Centrifugal Casting
- Continuous Filament Winding
- Discontinuous Filament Winding
