　　1. Corrosion-resistant FRP pipes can resist the corrosion of acid, alkali, salt, seawater, untreated sewage, corrosive soil or groundwater and other chemical fluids.

　　2. 具有良好耐热性和抗冻性的玻璃钢管的温度范围一般在-40℃~ 80℃之间。如果先用特殊的树脂，温度会更高。

　　2. The temperature range of FRP pipes with good heat resistance and frost resistance is generally between - 40 C and 80 C. If special resin is used first, the temperature will be higher.

　　FRP管的比重为1.7-1.9。与其他相同压力和直径的材料相比，FRP管的单位长度和重量约为钢管的30%。因此，它是非常方便的运输和安装。除安装钢管需要焊接防锈、防腐处理等程序外。

　　The specific gravity of FRP tube is 1.7-1.9. Compared with other materials with the same pressure and diameter, the unit length and weight of FRP pipe are about 30% of that of steel pipe. Therefore, it is very convenient to transport and install. In addition to installation of steel pipes need welding anti-rust, anti-corrosion treatment and other procedures.

　　玻璃钢管内表面光滑，粗糙度系数小。水力系数C可长期保持在145-150的范围内。试验结果表明，水流摩擦损失系数f为0.000915，可显著降低沿程流体压力损失，提高输送能力20%以上。

　　The inner surface of FRP pipe is smooth and its roughness coefficient is small. Hydraulic coefficient C can be maintained in the range of 145-150 for a long time. The experimental results show that the friction loss coefficient f of flow is 0.000915, which can significantly reduce the fluid pressure loss along the flow and improve the conveying capacity by more than 20%.

　　5、良好的电和热绝缘玻璃钢是非导体,管道保温很好,适合使用的传播,电信线密度区域和雷区,FRP管的传热系数非常小(0.25千卡/ m·h·℃),所以管的绝缘良好,更少的热量损失。

　　5. Good electrical and thermal insulation FRP is non-conductor, pipeline insulation is very good, the most suitable for use of transmission, telecommunications line density area and minefield, the heat transfer coefficient of FRP pipe is very small (0.25 kcal/m.h.C), so the insulation of the pipe is good, less heat loss.

　　6、不生锈是因为玻璃管是由非金属材料树脂和玻璃纤维复合而成，所以，无论是在使用过程中还是在闲置过程中，都不会生锈，所以没有必要进行防锈、除锈。7. 可根据具体使用情况，对缠绕玻璃钢管的具体性能和形状进行设计:

　　6. Non-rusting is because the glass tube is made of non-metallic resin and glass fibre. Therefore, no rust will occur in the process of use or idle, so there is no need for rust prevention and removal. 7. The specific performance and shape of wrapped FRP pipes can be designed according to the specific application conditions.

　　(1)可设计缠绕角，使管道具有不同的纵向/环形强度分布;

　　(1) The winding angle can be designed to make the pipeline have different longitudinal/annular strength distribution.

　　(2)可对管壁厚度进行设计，使管壁能承受不同的内外压力;

　　(2) The wall thickness can be designed so that the wall can withstand different internal and external pressures.

　　(3)该材料可设计成达到不同用途的耐腐蚀性、阻燃性、介电性;

　　(3) The material can be designed to achieve corrosion resistance, flame retardancy and dielectric properties for different purposes.

　　(4)可根据不同的安装条件，设计出适合的封头，以提高工程安装的速度。

　　(4) According to different installation conditions, suitable head can be designed to improve the speed of Engineering installation.

　　8、连接模式是各种灵活的缠绕玻璃钢管道连接方式有多种,主要包括:平端对接,(循环)法兰连接,插座插入胶连接,(与锁紧装置)o形环连接,螺杆连接,等等,根据具体的施工条件,灵活选择联合模式,以提高项目的可靠性。

　　8. Connection modes are various flexible connection modes of winding FRP pipes, including flat-end docking, (circular) flange connection, socket insertion glue connection, (with locking device), O-ring connection, screw connection, etc. According to specific construction conditions, flexible selection of joint modes can improve the reliability of the project.

　　9. 可修性强，维修方便，无锈蚀、无结垢，缠绕玻璃钢管水箱耐腐蚀性好，一般无需维修;即使需要维修，由于其重量轻，维修性强，所以维修非常方便。

　　9. Repairability is strong, maintenance is convenient, no rust, no scaling, winding FRP water tank corrosion resistance is good, generally do not need maintenance; even if need maintenance, because of its light weight, strong maintainability, maintenance is very convenient.
