Chemical Process Piping Pvt Ltd offers Glass-Reinforced Plastic-GRP Pipes. Chemical Process Piping Pvt Ltd is an ISO 9001:2000 certified company that manufactures FRP / GRP and Thermoplastic lined FRP products like Pipes, Fittings, Headers, Ducts, Stacks and Launders. The Glass-Reinforced Plastic-GRP Pipes are manufactured essentially by either the Band wound technique or the Filament wound technique.
Specifications of Glass-Reinforced Plastic-GRP Pipes are:
Band Wound Technique: The GRP pipes are manufactured by the Band wound technique wherein bands of Chopped Strand Mat and Woven Roving are impregnated with unsaturated polyester resin and wound in a definite angle to achieve circumferential and axial strengths.
Filament Wound Technique: The GRP pipes are manufactured by the Filament winding technique wherein glass ravings are impregnated with unsaturated polyester resin and wound in a definite angle to achieve circumferential and axial strengths. Prior to filament winding, a chemical resistance layer of 2.5 mm thickness is built using bands of CSM impregnated with the same resin. For special fluids the chemical resistance layer is built using polyester mats.
Available standards of Glass-Reinforced Plastic-GRP Pipes are:
- DIN 16965 / 16966
- ASTM 2310 / 2992 / 2996
- IS 12709
- AWWA C 950
- PS 15-69
