Mechanically wound FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is made of resin as a matrix and glass fiber as a reinforcing material through a special process.
This kind of pipeline has the advantages of corrosion resistance, leakage resistance, heat insulation performance, light weight and high strength, long life, strong designability, small fluid resistance, easy installation and low comprehensive cost. It can be widely used in petroleum, chemical, pharmaceutical, electric power, papermaking, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transportation, mining and other industries. It is an ideal pipeline for transporting liquids and gases. In recent years, China's glass fiber reinforced plastic pipe production has developed rapidly, the number has been increasing year by year, and the scope of application and departments has become wider and wider. Connection accessories: socket type, butt type, flange type, O-ring type elbow, T-shaped pipe, reducer, flat welding flange and other FRP pipes from the production process are mainly the following categories: pure FRP pipes, sand Pipes, high-pressure pipelines, and thermal insulation pipelines. The application fields of glass fiber reinforced plastic pipelines are mainly the following categories: petroleum pipelines, chemical pipelines, power pipelines, pharmaceutical pipelines, papermaking slurry, urban water supply and drainage pipelines, industrial sewage pipelines, desalination pipelines, gas pipelines, natural gas pipelines, etc. Fiber-wound glass steel pipe is mainly used in water conservancy, sewage, petroleum, chemical, power, metallurgy, medicine and other fields. It has the advantages of light weight, high strength, strong corrosion resistance, convenient installation and maintenance. The product has been successfully applied throughout the country.
I. Features 1. It has excellent physical properties. The specific gravity of glass steel pipe is 1.8-2.1, which is about 1/4 of steel. It has higher strength than steel, cast iron and plastic. The weight of glass steel pipe is generally not greater than that of steel pipe of the same specification. / 3, excellent physical and mechanical properties. In addition, the expansion coefficient of FRP 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 and long service life, suitable for conveying various media such as various acids, alkalis, salts and organic solvents.
3. Excellent hydraulic characteristics, which is one of the important characteristics of FRP 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 electricity and reducing operating costs. The inner surface of glass fiber reinforced plastic is quite smooth. The general surface roughness can be 0.0084, which can be considered as "hydraulic smooth pipe". During operation, the internal surface of steel pipes, cast iron pipes, cement pipes, etc. often undergoes local corrosion and becomes rougher. , While FRP has always maintained the smooth surface of the new tube.
4. Low installation and maintenance costs. Generally speaking, FRP pipes do not need 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 small, 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 installation and maintenance costs, which has been proven by many engineering practices at home and abroad.
5. Great design flexibility and short modification period. Glass fiber reinforced plastic is a fiber-reinforced material impregnated with resin, which is wound on the core mold layer by layer according to specific process conditions and cured appropriately. The tube wall is a layered structure that can be modified by changing the resin system or using different reinforcements. 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 glass fiber reinforced plastic pipes with some special properties. The short modification period is a prominent feature of fiber-wound composite materials, and isotropic metal pipes cannot be compared with it.
