The performance characteristics of glass fiber conduit:
1. Excellent corrosion resistance: Made primarily from high molecular weight unsaturated polyester resin and glass fiber, glass reinforced plastic (GRP) effectively resists corrosion from acids, alkalis, salts, untreated sewage, corrosive soils, chemical wastewater, and numerous chemical liquids. Standard sizes range from DN50mm to DN300mm. Length: 6 meters per piece.
2. Excellent aging resistance and heat resistance: Glass steel pipes can be used for a long time within a temperature range of -40℃ to 70℃, and special high-temperature resistant resins can operate normally above 200℃.
3. Excellent frost resistance: The pipe will not crack after freezing when the temperature drops below -20℃.
4. Lightweight, high strength, and easy to transport. Glass fiber pipes are not only lightweight, high-strength, and highly malleable with ease of transportation and installation, but they also facilitate the installation of various branch lines, featuring simple installation techniques.
5. Excellent hydraulic conditions: smooth inner wall, strong conveying capacity, no scaling, no rust, low water resistance.
6. Excellent Design Flexibility: Glass steel pipes can be designed and manufactured to meet various specific customer requirements, such as different flow rates, pressures, burial depths, and load conditions, resulting in pipes with different pressure and stiffness grades.
7. Low maintenance costs: Due to the properties of corrosion, wear, frost, and dirt resistance, glass steel pipes do not require rust-proofing, anti-pollution, insulation, or thermal insulation measures and maintenance. Underground pipelines do not need cathodic protection, which can save over 70% of maintenance costs for the project.
8. Excellent Abrasion Resistance: Conducted a rotational abrasion test on water containing a large amount of mud and sand by filling it into pipes. After 3 million rotations, the wear depth on the inner wall of the pipes was measured as follows: 0.53mm for steel pipes coated with tar and porcelain enamel, 0.52mm for steel pipes coated with epoxy resin and tar, and 0.21mm for glass steel pipes treated with surface hardening. Thus, glass steel exhibits superior abrasion resistance.
9. Excellent electrical insulation: Glass fiber reinforced plastic (FRP) is a non-conductor, with exceptional electrical insulation properties for pipes, boasting an insulation resistance of 10^12 to 10^15 Ω.cm. It is suitable for use in areas with dense transmission and telecommunication lines as well as regions prone to lightning. The thermal conductivity of FRP is very low, at only 0.23, which is one-fifth that of steel, making the pipe excellent in thermal insulation.
