FRP filament winding process piping mainly used for irrigation, sewage, petroleum, chemical, power, metallurgy, medicine, etc., with a light weight, high strength, corrosion resistance, installation and easy maintenance. The product has been successfully applied throughout the country. [Features] 1, has excellent physical properties, the proportion of FRP pipe is 1.8-2.1, which is about 1/4 of steel, high-strength steel, cast iron and plastic, weight FRP pipe is generally not more than the same size steel pipe 1 / 3, excellent physical and mechanical properties, in addition, the expansion coefficient of glass and steel pipe roughly the same, only 0.5% of the thermal conductivity of steel, is a good thermal and electrical insulator. 2, chemical resistant, long life, suitable for handling a variety of different media acids, bases, salts and organic solvents. 3, the hydraulic characteristics of excellent hydraulic characteristics is an important feature of the glass tube. Excellent hydraulic characteristics of the fluid pressure head loss means little, you can use a smaller diameter or smaller power pump, thereby reducing the initial investment pipeline projects, save energy and reduce operating costs. FRP inner surface is quite smooth, rough surface generally desirable rate 0.0084, almost as a "smooth water pipe" in the operation, the inner surface of the pipe, cast iron pipes, cement pipes, etc., often localized corrosion, has become increasingly rough while the fiberglass has maintained a smooth surface state newborn tube. 4, installation, low maintenance costs, in general, do not need a glass pipe embalmed; insulation layer can be thinned, others do not even insulated; pipeline relatively light, small lifting equipment tonnage, low power consumption, glass pipe length ratio of cement cast iron pipe and pipe length, fittings relative reduction, which will reduce installation and maintenance costs, and this has been proved by many domestic and foreign engineering practice. 5, design flexibility, short cycle modifications. FRP is impregnated with resin matrix fiber reinforced material, in accordance with the specific process conditions is wound onto the mandrel layer by layer and made of a suitable cure, the wall is a layered structure, by changing the resin system or use different enhancement material to adjust the physical and chemical properties of the glass tube to accommodate different media and working conditions made different pressure levels, or have some special properties of the glass tube. Modified cycle is short, is filament wound composite notable feature isotropic metal pipe can not be compared.
