Fiber Glass Reinforced Plastic Pipe FRP/GRP/GRE:-
FRP/GRP/GRE pipe is in the filament winding process, using the quartz sand layer will strengthen, make it have a sandwich structure, such as reducing the comprehensive cost of the pipeline, and improve the overall strength and stiffness of the pipeline. A high-pressure FRP/GRP/GRE pipe is a new type of nonmetallic pipe. In its making, glass roving, soaking by low viscosity but strong adhesive bonding resin, winds around mold at the preset angle and layers. It has to be cured, released from the mold and then processed. Excellent corrosion resistance, high endurance, lightweight and high strength are among its special properties.
Characteristics:
1. High strength, Used for the carriageways directly buried, don't need concrete cover, Can speed up the construction progress
2. Flexibility, Resistant to outside pressure and damage
3. Electric insulation, flame retardant, heat resistant performance is good, can be used for a long time in 130 degrees heat and not easy deformation.
4. Resistance corrosion, long service life, can resist acid, alkali and salt corrosion; it can be used more than 50 years.
5. The smooth inner wall, protect the cable.
