玻璃钢通风管道的质量
玻璃钢通风管道的质量
Quality of FRP ventilation pipe
1、耐腐蚀性 FRP管道能够抵抗酸、碱、盐、海水、未经处理的污水、腐蚀性土壤或地下水及众多化学流体的腐蚀。
1. Corrosion resistant FRP pipes can resist the corrosion of acid, alkali, salt, seawater, untreated sewage, corrosive soil or groundwater and many chemical fluids.
2、耐热抗冻性好 FRP管的温度使用范围一般在-40℃~80℃之间，若先用特殊树脂其使用温度可达到更高。
2. The temperature range of FRP pipes with good heat and frost resistance is generally between - 40 ℃ and 80 ℃. If special resin is used first, the service temperature can be higher.
3、轻质高强，运输安装方便 FRP管道的比重为1.7-1.9，与同压力、同管径的其他材质管道比较，FRP管道单位长度、重量约等于钢管的30%，因此运输安装十分方便，FRP管道每根长度可达12m，安装快速简便。另外可免除安装钢管所需的焊接和防锈、防腐处理等工序。
3. It is light and high-strength, convenient for transportation and installation. The proportion of FRP pipes is 1.7-1.9. Compared with other pipes of the same pressure and diameter, the unit length and weight of FRP pipes are about 30% of the steel pipes. Therefore, it is very convenient for transportation and installation. Each FRP pipe can be up to 12m long, and the installation is fast and simple. In addition, welding, anti rust and anti-corrosion treatment for steel pipe installation can be avoided.
4、摩擦阻力小，输送能力高 FRP管道内表面非常光滑，糙率系数小，水利系数C可长期保持在145-150范围内，经测试得到其水流摩阻损失系数f为0.000915，能显著减少沿程的流体压力损失，提高输送能力20%以上。
4. The friction resistance is small, the inner surface of FRP pipe with high transportation capacity is very smooth, the roughness coefficient is small, and the hydraulic coefficient C can be kept in the range of 145-150 for a long time. The test results show that the friction loss coefficient f of the flow is 0.000915, which can significantly reduce the fluid pressure loss along the way and improve the transportation energy by more than 20%.
5、电、热绝缘性好 FRP是非导体，管道的绝缘性好，最适应使用于输电、电信线路密集区和多雷区，FRP管的传热系数很小(0.25kcal/m·h·℃)，因此管道的保温性好，热损失少。
5. FRP with good electrical and thermal insulation is non-conductor, and the insulation of the pipeline is good, which is most suitable for the dense area of power transmission and telecommunication lines and multi lightning area. The heat transfer coefficient of FRP pipe is very small (0.25kcal / m · h ·℃), so the insulation of the pipeline is good and the heat loss is small.
