1. Good corrosion resistance. As the main material of FRP is composed of unsaturated polyester resin and fiberglass, it can effectively resist the corrosion of acid, alkali, salt and other media, and the erosion of untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. In general, it can maintain the safe operation of pipelines for a long time.
2、抗老化性能和耐热性能好。玻璃钢管可在-40℃～70℃温度范围内长期使用，采用特殊配方的耐高温树脂还可在200℃以上温度正常工作。长期用于露天使用的管道，其外表面添加有紫外线吸收剂，来消除紫外线对管道的辐射，延缓玻璃钢管道的老化。
2. Good ageing resistance and heat resistance. FRP pipe can be used for a long time in the temperature range of - 40 ~70 ~C, and the high temperature resistant resin with special formulation can work normally at temperatures above 200 ~C. For long-term use in open air pipelines, ultraviolet absorbent is added to the outer surface to eliminate the radiation of ultraviolet radiation to pipelines and delay the aging of FRP pipelines.
3、抗冻性能好。在零下20℃以下，管内结冰后不会发生冻裂。
3. Good frost resistance. The freezing crack will not occur when the tube freezes below 20 C.
4、重量轻、强度高、运输方便。玻璃钢管不但重量轻、强度高、可塑性强、运输与安装方便，还容易安装各种分支管，且安装技术简单。
4. Light weight, high strength and convenient transportation. FRP pipe is not only light in weight, high in strength, strong in plasticity, convenient in transportation and installation, but also easy to install various branch pipes, and the installation technology is simple.
5、水力条件好。内壁光滑、输送能力强，不结垢、不生锈、水阻小。
5. Good hydraulic conditions. Smooth inner wall, strong conveying capacity, no scaling, no rust, low water resistance.
6、可设计性好。玻璃钢管可根据用户的各种特定要求，诸如不同的流量，不同的压力，不同的埋深和载荷情况，设计制造成不同压力等级和刚度等级的管道。
6. Good designability. FRP pipes can be designed and manufactured according to users'specific requirements, such as different flow rates, different pressures, different burial depths and loads.
7、维护成本低。玻璃钢管由于上述的耐腐，耐磨和抗冻和抗污等性能，因此工程不需要进行防锈，防污，绝缘，保温等措施和检修。对地埋管无需作阴极保护，可节约工程维护费用达70%以上。
7. Low maintenance cost. Due to the above corrosion resistance, abrasion resistance, frost resistance and pollution resistance of FRP pipes, there is no need to carry out rust prevention, pollution prevention, insulation, insulation and other measures and maintenance. No cathodic protection is needed for buried pipes, which can save more than 70% of the project maintenance cost.
8、耐磨性好。把含有大量泥浆，沙石的水，装入管子中进行旋转磨损影响对比试验。经300万次旋转后，检测管内壁的磨损深度如下:用焦油和瓷釉涂层的钢管为0.53mm，用环氧树脂和焦油涂层的钢管为0.52mm，经表面硬化处理的钢管为玻璃钢管为0.21mm。由此玻璃钢耐磨性能好。
8. Good wear resistance. The water containing a large amount of mud and sand was put into the pipe to carry out a comparative test on the effect of rotational wear. After 3 million rotations, the wear depth of the inner wall of the pipe is as follows: the steel pipe coated with tar and enamel is 0.53 mm, the steel pipe coated with epoxy resin and tar is 0.52 mm, and the steel pipe hardened by surface is 0.21 mm. Therefore, FRP has good wear resistance.
9、电热绝缘性好。玻璃钢是非导体，管道的电绝缘性特优，绝缘电阻在1012-1015Ω.cm，最适应使用于输电，电信线路密集区和多雷区玻璃钢的传热系数很小，只有0.23，是钢的千分之五，管道的保温性能优异。
9. Good electrical and thermal insulation. Fiberglass reinforced plastics (FRP) is a non-conductor with excellent electrical insulation. Its insulation resistance is 1012-1015_.cm. It is most suitable for power transmission. The heat transfer coefficient of FRP in dense areas of telecommunication lines and multi-minefield areas is very small, only 0.23, which is five thousandths of steel. The insulation performance of pipelines is excellent.
10、摩擦阻力小输送能力高。玻璃钢管内壁非常光滑，糙率和摩阻力很小。糙率系数为0.0084，而混凝土管的n值为0.014，铸铁管为0。013，因此，玻璃钢管能显著减少沿程的流体压力损失，提高输送能力。因此，可带来显著的经济效益:在输送能力相同时，工程可选用内径较小的玻璃钢管道，从而降低一次性的工程投入；采用同等内径的管道，玻璃钢管道可比其他材质管道减少压头损失，节省泵送费用。此外，玻璃钢管道可缩短泵送时间，减少长期运行费用。
10. Small frictional resistance and high conveying capacity. The inner wall of FRP pipe is very smooth with little roughness and friction. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014 and that of cast iron pipe is 0. 013, therefore, FRP can significantly reduce fluid pressure loss along the way and improve the transport capacity. Therefore, it can bring remarkable economic benefits: when the transportation capacity is the same, the FRP pipeline with smaller inner diameter can be used to reduce the one-time project investment; when the pipeline with the same inner diameter is used, the FRP pipeline can reduce the pressure head loss and save the pumping cost compared with other pipelines with the same inner diameter. In addition, FRP pipe can shorten pumping time and reduce long-term operating costs.
