Products 
 Fiberglass Reinforced Plastic Pipe is a resin matrix materials, glass fiber and its products as reinforcing material, quartz sand filling material made of new composite materials. Its excellent resistance to corrosion, hydraulic characteristics of lightweight, high strength, conveying flow, easy installation, short construction period and comprehensive investment and low, and become the best choice of the chemical industry and drainage works. 
 Glass Reinforced Plastic Pipe is a thermosetting resin matrix, glass fiber and its products as reinforcing material, the use of computer-controlled mechanical winding process made. Process structure can be divided into two types of pure glass pipes and glass Reinforced Plastic Pipe, the main difference between the two solid glass, steel structure for the filament winding, which is the continuous filament winding and coarse molding process, the wall of the middle layer made of resin mortar layer to increase the wall thickness, stiffness, enhanced resistance to external carrying capacity of. 

 Features 
 First, with excellent mechanical and physical properties 
 Second, resistance to corrosion, aging, long service life 
 Third, the smooth inner surface, the hydraulic performance 
 Fourth, light weight, transportation, installation, easy maintenance 
 Five, burst pipes, interface, security 
 Sixth, no poison, no secondary pollution 


 Features 
 1, with excellent mechanical and physical properties 
 FRP pipe has excellent mechanical physical properties, density 1.9 ⅹ 103Kg/m3. About 1/4 of the steel ring to the tensile strength of approximately 300MPa axial tensile strength of about 160MPa. Its intensity is much higher than other materials, including steel, cast iron, plastic, etc. In addition, it is thermal and electrical insulators. 
 2, corrosion resistance, aging resistance, long service life 
 Glass pipe with a special chemical resistance against acids, alkalis, salts, seawater, sewage, corrosive soil, and a variety of inorganic solvents, organic solvents against the need for any preservative treatment. Products according to the American ASTM standard design, the design life of 50 years, 50 years after its strength retention was still as high as 64 to 70. 
 3, the inner surface of the smooth hydraulic performance 
 FRP pipe surface is quite smooth, and the Manning coefficient is only 0.0084. The hydraulics HazenwilliamsC coefficient may be long maintained in the range of 145 ~ 150. This means that glass pipes conveying fluid pressure head loss can improve transportation for more than 20 percent, saving power and energy of the pump (about 30 ~ 40), to reduce long-term operating costs. Therefore, in the same working conditions may choose to use a smaller diameter or small power pump, thereby reducing the one-time investment of the project. 
 4, light weight, transportation, installation, easy maintenance 
 As the glass pipe, the proportion of small, light weight, the path condition, its weight per unit length is approximately equal to 30% of the steel pipe is 8 to 10 percent of the weight of concrete pipe and single pipe length, fittings, transportation and installation is very convenient. Glass steel without corrosion, rust, stain resistant, insulation, and other processing, saving maintenance costs of running processes. 
 5, burst pipes, reliable interfaces, security 
 Winding FRP pipe has a special structure and excellent performance, when the media pressure reached its limit, undermine the performance of the pipeline for the sweating and not burst pipe, when the pressure drops to a certain range, to continue its normal use. In addition, the pipe socket dual "O"-ring flexible connection in the joints, pressure test device, the installation process, a single interface, a water seal, you can ensure that the internal pressure seal, but also ensure that the vacuum seal conditions to ensure safe and reliable interface. 
 6, no poison, no secondary pollution 
 Pipe lining can choose the food-grade resin manufacturing to meet the technical specifications of glass fiber reinforced unsaturated polyester resin, food containers, reach GB13005-91 health standards, and fully meet the use requirements of the urban water supply project. Meanwhile, in the course of non-corrosive, scaling, and breeding ground for algae and other micro-organisms, the medium does not cause secondary pollution.
