FRP pipes

Product introduction: FRP 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. Properties and advantages: Because of FRP pipes in the wall design, make its sand layer with pure glass tube, not only has the advantages of high compared with the performance, and buried pipes need high rigidity and low cost, easy installation, no need to repair, in water or other liquids on the application of more and more. Application: Petroleum, chemical industry, electric power, water conservancy, papermaking, urban water supply and drainage, environmental protection, sewage treatment plant, heat preservation, the pipeline. The FRP tubes 1, light weight, high strength, high stiffness FRP pipe inner layer and layer are, resin mortar layer and protective coating, it is the proportion of 1.7-2.1 for steel, steel tube, the 1/4, three of the four prestressed concrete. Due to the resin mortar layer on both sides of the fiber winding is enhanced, and the layer structure of the fiber content is 70%, can fully satisfy requirement of pipeline, due to the strength of resin mortar layer around the middle layer is enhanced, low stress area in the lower strength can greatly improve the situation of steel pipe. 2 and anti-corrosion properties FRP tubes mainly depends on the corrosion resistance of the lining of the resin lining of resistance, but according to the condition to select different grades of resin. The FRP pipe inner layer is adopted for the rich digital fiber, 80 percent of the resin content can ensure pipe anticorrosion, leakage. 3, hydraulic properties FRP pipe, very smooth surface roughness is tiny, not only the product is smooth, and use a few years later, smooth wall again, no seaweed and other aquatic derivatives attached. Water can be maintained for a long time in the coefficient of C, 145-150, within the scope of the water tested friction loss coefficient 0.000915 f, than concrete pipe (f = 0.00232) and tube (f = 0.00179) can significantly reduce frictional pressure loss, improve the transmission capacity above 20%. Therefore, in the transport capacity in diameter, can choose the lesser FRP tubes, thereby reducing engineering time. Water is the specific ability see table 1 and figure 1. 4, FRP pipe health performance FRP pipe materials are used unsaturated polyester and glass fiber through certain technology, the pipe inner surface is very slick, and forty years, and in the pap hardness of unsaturated polyester resin itself through the national health and anti-epidemic departments of inspection, so the FRP pipe products have passed national health and anti-epidemic departments of inspection, so the FRP pipe can meet hygiene standards, domestic and drinking water for over 20 years. Five, the seismic performance Because of FRP pipes and flexible tube between rigid pipe, so it's good aseismic performance in the strong force, won't appear below deformation, destruction, because the FRP pipe deformation in 25%, stratification, no crack. 6 and abrasion Due to the pipe inner surface USES glass, high wear-resisting performance can be greatly improved the resin wearability of products, so as to improve the service life of the product. 7 resistance, low temperature performance FRP pipe can not DongLie -40c does not reduce the strength, the pipeline. 8 and environmental adaptability FRP pipe can be applicable to various environment, such as: the beach, sea, rivers and mountains and plains, swamps, and desert, etc., with convenient transportation service life is long, etc. Update Date:2010/6/10 3:10:29
