Plastic FRP composite pipe is the third generation of new cable protective sleeve, which is a new product developed by our company to overcome various defects of sand filled FRP cable conduit used in modern market. This product combines PVC, PE, MPP plastic and glass fiber reinforced plastics into one. The inner surface layer of the product is made of PVC, PE and MPP, which has fatal defects such as preventing the cable from loosening from the inner surface and blocking the cable. The outer layer is a glass fiber reinforced plastics layer, which is wrapped with glass fiber impregnated with flame-retardant resin. It is superior to the sand containing glass fiber reinforced plastics cable conduit used in the market. In addition, it is also a substitute for galvanized steel pipe Vinylon cement pipe is an ideal high-quality pipe product.
