1.Introduction
FRP pipe (FRP),FRP Tube,Fiber winding FRP tubes with reliability, safety and efficiency, mainly used for buried tube and long-distance pipelines, high strength, corrosion resistance, long service life, operation and maintenance costs low characteristic, can save money for construction projects.
2.Characteristics
1)high strength: the proportion of FRP for 1.65-2.0. For the same length, diameter of unit weight only one-third of the carbon steel and cast iron pipe of FRP pipes only 1/5, prestressed concrete pipe 1/10, in construction, reduced cost, improve the lifting speed, etc.
2)the hydraulic characteristics of good: this o: this one characteristic in water supply and drainage field application, intion, intion, in particular the hydraulic characteristics.
2.1pipeline pump can save cost.
2.2 reduce diameter size.
2.3 to shorten the time of the pump.
2.4 FRP pipe culvert scaling, not long, make water without rack cleaner by secondary pollution.
3)water resistant, corrosion resistance of FRP pipes excellent corrosion resistance, anti-corrosion, reduced costced cost prolong the life, At the same time as the water conveyance that does not rust, not by a second pollution. Also can used for conveying sewage and sludge, the sea, and other media.
4)compression: the technique requirements, design and manufacture of the pressure piping and fittings, technical requirements of 1.5 times the pressure hydrostatic test.
5) the interface sealing, no leakage, not crack, increase water safety and reliability.
6)non-toxic, can be used for conveying water.
3.Application
A water transport lnsport line pipe and pipes
A sewage pipe, water pipe
A irrigated agriculture tube
4.Main forming process
Controlled by computer, in accordance with the provisions in the mandrel glass fiber winding with the same process manufacturing lining, gel according to design linear and good after winding layer thickness, and will be mixed with the mortar quartz resin in structure layer, finally winding outside layer.
5.The original and auxiliary materials
resin, cut short fibers, continuous glass fiber
