The performance features of glass fiber reinforced plastic (GRP) cable conduits:
1. Excellent Corrosion Resistance: Made primarily of high molecular weight unsaturated polyester resin and glass fiber, fiberglass composite materials effectively resist corrosion from acids, alkalis, salts, untreated sewage, corrosive soil, chemical wastewater, and numerous chemical liquids. Standard Sizes: DN50-300mm, 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 freeze resistance: The pipe will not crack after freezing inside at temperatures below -20℃.
4. Lightweight, high strength, and easy to transport. Glass steel pipes are not only lightweight, strong, highly pliable, and easy to transport and install, but they also facilitate the installation of various branch pipes with simple installation techniques.
5. Excellent hydraulic conditions: smooth inner wall, strong conveying capacity, no scaling, no rust, and low water resistance.
6. Good Designability: Glass steel pipes can be designed and manufactured to meet various specific requirements of users, such as different flow rates, pressures, burial depths, and load conditions, resulting in pipes of different pressure and stiffness grades.
7. Low maintenance cost: Due to the corrosion, wear, frost, and dirt resistance of glass steel pipes, engineering projects do not require rustproofing, anti-dirt, insulation, and thermal preservation measures or maintenance. No cathodic protection is needed for buried pipes, which can save over 70% of maintenance costs.
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 pipe was 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 steel pipes with surface hardening treatment and glass reinforced plastic. Thus, glass reinforced plastic exhibits superior abrasion resistance.
9. Excellent electrical insulation: Glass fiber reinforced plastic is a non-conductor, with exceptional electrical insulation properties for pipelines. The insulation resistance ranges from 10^12 to 10^15 Ω.cm, making it suitable for use in areas with dense power transmission and telecommunication lines, as well as regions prone to lightning. The heat transfer coefficient of glass fiber reinforced plastic is very low, at only 0.23, which is one-fifth that of steel, and the pipeline has excellent thermal insulation performance.
