FRP flange

1. It has excellent physical properties. The specific gravity of FRP flange material is 1.8-2.1, which is about 1/4 of steel. Its specific strength is higher than that of steel, cast iron and plastic. The weight of FRP flange channel is generally not greater than the same specifications. . 1/3 of the steel pipe has excellent physical and mechanical properties.

1. It has excellent physical properties. The specific gravity of FRP flange material is 1.8-2.1, which is about 1/4 of steel. Its specific strength is higher than that of steel, cast iron and plastic. The weight of FRP flange channel is generally not greater than the same specifications. . One third of the steel pipe has excellent physical and mechanical properties. In addition, the expansion coefficient of the FRP flange is roughly equivalent to that of steel, and the thermal conductivity is only 0.5% of steel. It is a good thermal and electrical insulator.

2, chemical corrosion resistance, long service life, suitable for conveying various acids, alkalis, salts and other different media.

3, excellent hydraulic characteristics, hydraulic characteristics is one of the important characteristics of glass steel pipes. Excellent hydraulic characteristics means that the fluid head loss is small, and a smaller diameter or smaller power delivery pump can be selected, thereby reducing the initial investment in pipeline engineering, saving electrical energy, and reducing operating costs. The inner surface of glass fiber reinforced plastic is quite smooth, and the general surface roughness can be 0.008, which can almost be considered as a "hydraulic smooth pipe". During operation, the internal surfaces of steel pipes, cast iron pipes, cement pipes, etc. often undergo local corrosion and become more and more Rough, while FRP always keeps the surface of the new tube smooth.

4. Low maintenance costs. Generally speaking, FRP pipes do not need special anti-corrosion treatment; the insulation layer can be thinned, or no additional insulation treatment is required; the pipeline is lighter, the tonnage of the lifting equipment is small, the power consumption is less, and the length of the FRP pipe is longer than cement. The length of pipes and cast iron pipes and the relative reduction of joints will reduce and maintain costs, which has been proven by many engineering practices.

5. Great design flexibility and short modification period. Glass fiber reinforced plastic is made of a fiber-reinforced material impregnated with a resin matrix, which is wound around a core mold layer by layer according to specific process conditions and appropriately cured. The tube wall is a layered structure that can be changed by changing the resin system or using a different Strong materials to adjust the physical and chemical properties of FRP, in order to adapt to different media and working conditions to make different pressure levels or FRP with some special properties. The short modification period is a prominent feature of fiber-wound composite materials, and isotropic metal pipes cannot be the same.
