Glass fiber reinforced plastic pipes and environmental protection complement each other
In fact, we all know that with the development of society, people's living standards continue to improve. Now, as far as glass fiber reinforced plastic pipes are concerned, the current needs are from different market needs. For example, the main applications are municipal and urban Transportation, power distribution network, and other fields are mainly due to the fact that FRP pipes are non-toxic, have no secondary pollution to water quality, do not need to take anti-corrosion measures, have a long service life, and are simple and convenient to install and operate.
1) Good corrosion resistance, no impact on water quality: FRP pipes can resist the erosion of acids, alkalis, salts, seawater, untreated sewage, corrosive soil or groundwater and various chemical fluids. Compared with traditional pipes, the use of Longer life, design life is generally more than 50 years.
2) Anti-fouling and anti-fouling: The surface of unsaturated polyester resin is clean and smooth, and will not be contaminated by microorganisms such as shellfish and fungi in the ocean or sewage, thereby increasing the roughness, reducing the cross section and increasing the maintenance cost. Glass fiber reinforced plastic pipes have no such pollution, and they are clean for a long time. At the same time, due to their smooth water-resistant walls and excellent corrosion resistance, they will not produce scale and microorganisms, which effectively guarantees the water quality and maintains the stability of water resistance. In the future, there will still be increased water resistance and surface fouling.
3) Good heat resistance and frost resistance: This resin has good toughness and high strength of -30 ℃. It can be used for a long time in the range of -50 ℃ to 80 ℃. Specially formulated resin can also work above 110 ℃.
4) Light weight, high strength, convenient transportation and installation:
5) Small friction resistance and high conveying capacity: The inner wall of the glass steel pipe is smooth, the roughness is small, the friction is small, the roughness coefficient is 0.0084, the concrete pipe N value is 0.014, and the cast iron pipe N value is 0.013. Therefore, FRP can significantly reduce the fluid pressure loss along the pipeline, improve the transportation capacity, and have significant economic benefits:
6) Good electrical and thermal insulation: FRP is a non-conductor, and the pipe has excellent electrical insulation performance. The insulation resistance is 1012-1015NaN, which is most suitable for power transmission and telecommunication line dense areas and minefields. The heat transfer coefficient of FRP is very small. , 0.23, No. 5 steel, pipes have excellent thermal insulation properties.
7) Good abrasion resistance: Put the water containing a lot of mud and sand into the pipe to perform a comparative test of the rotary abrasion effect. After 3 million rotations, the inner wall wear depth is 0.53mm for tar and enamel-coated steel pipes and epoxy-coated Resin and tar steel pipes are 0.52mm and steel pipes are har. The surface area is 0.48mm and the glass steel pipe is 0.21mm, which indicates that its wear resistance is better.
8) The project's comprehensive benefits are good: Comprehensive benefits refer to long-term characteristics formed by many factors such as construction investment, installation and maintenance costs, service life, energy conservation and consumption reduction, and steel saving. The comprehensive benefits of glass fiber reinforced plastic pipes are desirable, especially the larger the diameter, the lower the cost. When further considering the buried underground, the pipeline can be used by several generations without annual maintenance, which can give play to its superior comprehensive benefits.
In fact, through the topics mentioned in the article about the complementarity of glass pipes and environmental protection, I have a simple view of myself, I hope to have a great inspiration for everyone in the future, and finally I wish everyone a happy life.
