Glass Reinforced Polyester pipes are manufactured with polyester resins and fibrous glass reinforcements, to which inorganic filler can be added. The design philosophy of GRP pipes is to provide products with suitable properties and the required margin of safety that will enable the pipe to satisfy mechanical requirements even after an extended period of operation (50 years) under typical service conditions.
Glass Reinforced Polyester pipes represent the ideal solution for conveying any class of water and the majority of chemicals, because they combine the advantage of corrosion resistance, which is typical of plastics, and high mechanical strength, typical of steel.
GRP pipes can be produced with continuous (CFW) and discontinuous (DFW) manufacturing process.
GRP pipes are joined with:
- GRP Sleeve
- GRP Bell & Spigot
- GRP Flanges
- GRP Lamination - welding
Available are all standard fittings, which are:
- Elbows of any degree
- Fix, loose, blind flanges
- Equal, reduced, lateral tees
- Concentric, eccentric reducers
- End caps
Fittings and special items are manufactured using the hand lay-up technique. The chemical barrier and the top coat of fittings are equal to the one of the pipe; the structural wall is made with alternated layers of mat and woven roving.
