1. Good corrosion resistance. Because the main raw materials of glass fiber reinforced polymer unsaturated polyester resin and glass fiber components, can effectively resist acid, alkali, salt and other media corrosion and untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquid erosion, in general, can maintain the safe operation of the pipeline for a long time.
2. Anti-Aging and heat-resistant properties. FRP pipe can be used in the -40℃~70℃ temperature range for a long time, the use of special formulations of high temperature resin can also be 200 ℃ above normal working temperature. Long-term use of open air pipelines, the external surface of the addition of ultraviolet absorbent, to eliminate ultraviolet radiation on the pipeline, delaying the aging of FRP pipes.
3. Good antifreeze performance. Below the 零下20℃, the tube freezes after freezing.
4. Light weight, high strength, convenient transportation. FRP tube not only light weight, high strength, plasticity, transport and installation is convenient, but also easy to install a variety of branch tubes, and installation technology simple.
5. Good hydraulic conditions. The inner wall is smooth, the conveying ability is strong, does not scale, does not rust, the water resistance is small.
6. Good design. FRP pipe can be designed and manufactured into different pressure levels and stiffness levels according to the specific requirements of the user, such as different flow, different pressure, different depth and load.
7. Low maintenance cost. FRP pipe due to the above corrosion resistance, wear resistance and antifreeze and anti-fouling performance, so the project does not need to rust, anti-fouling, insulation, insulation and other measures and maintenance. No cathodic protection is needed for the buried pipe, which can save more than 70% of the project maintenance cost.
