Seven characteristics of FRP wind pipe

1、 玻璃钢风管耐腐蚀性 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. The corrosion resistance FRP pipes of the FRP wind pipe can resist corrosion of acid, alkali, salt, sea water, 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, heat and frost resistance is good. The temperature range of FRP pipe is usually between 40 and 80 degrees. If the 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, light and high strength, transportation and installation convenient FRP pipe proportion of 1.7 - 1.9, compared with the same pressure, the same pipe diameter of other material pipes, FRP pipe length, weight is equal to 30% of the steel pipe, so transportation and installation is very convenient, FRP pipe length can reach 12M, easy to install fast. In addition, the welding and antirust and anticorrosive treatment procedures for the installation of steel pipes can be exempted.

4、玻璃钢风管摩擦阻力小，输送能力高 玻璃钢风管内表面非常光滑，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 of the glass steel wind pipe is small. The inner surface of the high fiberglass pipe is very smooth and the coefficient of roughness is small. The water coefficient C can be kept in the 145-150 range for a long time. The friction loss coefficient f of the water flow is 0.000915, which can significantly reduce the loss of fluid pressure and increase the transport capacity 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, electrical and thermal insulation good FRP is non conductor, the insulation of the pipeline is good, the most suitable for use in the transmission, telecommunication line intensive area and multi mine area. The heat transfer coefficient of the FRP tube is very small (0.25kcal/m. H. C), so the heat insulation of the pipeline is good, and the heat loss is less.

6、不生锈由于玻璃钢风管是由非金属材料树脂及玻璃纤维复合而成，所以，它们不论在使用过程还是在闲置过程中，均不会生锈，因而也就无需进行防锈、除锈处理。

6. Without rust, the FRP wind pipe is made of nonmetallic material resin and glass fiber, so they do not rust in the process of use or in the idle process, so there is no need for rust prevention and rust removal.

7、可设计性强 根据具体使用情况，可对缠绕玻璃钢管的具体性能及形状进行设计。

7. It can be designed strongly. According to the specific usage, we can design the specific performance and shape of the FRP pipe.
