[RPMP gradually in recent years abroad in the petrochemical, water supply and drainage, and other fields to promote the use of a new type of flexible non-metallic composite pressure pipe, and its essence is a glass fiber reinforced materials, thermosetting unsaturated polyester resin as matrix, quartz sand sandwiched pressure tube (abbreviation name FRP, codenamed FWRPMP, referred Plastic Pipe). FRP pipe is currently executing the building materials industry standard "glass fiber reinforced thermosetting resin sand wound pressure tube." RPMP performance and advantages of high strength ①. Glass fiber according to certain rules to form a multi-layered distribution network, greatly improving the pipeline loop through the axial tensile strength index wound. ② stiffness. Within the wall, there are 0.3 ~ 0.8mm diameter quartz sand sandwiched between the outer layer, the impregnated resin cured to improve the rigidity of the glass tube. ③ impermeability good corrosion resistance. The polymer compound filled in the unsaturated polyester resin and glass fibers and glass fiber cyberspace good wetting, not only play a role in load transfer after curing and anti-leakage, but also serve to prevent acid, alkali, salt corrosion, but also medium protection conveyed no secondary pollution. ④ RPMP gradually in recent years, at home and abroad in the petrochemical, water supply and drainage, and other fields to promote the use of a new type of flexible non-metallic composite pressure pipe, and its essence is a glass fiber reinforced materials, thermosetting unsaturated polyester resin as matrix, quartz sand sandwiched pressure tube (abbreviation name FRP, codenamed FWRPMP, referred Plastic Pipe).
