Glass Fiber Reinforced Plastic GRP winding pipe
GRP pipe is in the filament winding process, using quartz sand layer will strengthen, make its have sandwich structure, such as reducing the comprehensive cost of the pipeline, and improve the overall strength and stiffness of the pipeline.
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.
