玻璃钢夹砂管性能特点

玻璃钢夹砂管道是一种性能优异的新型复合材料管材，它具有其它传统管材（金属管材、混凝土管材、塑料管材）无法比拟优越性能： FRP pipe grit pipe is a new type of composite pipe with excellent performance. It has other traditional pipe material (metal pipe, concrete pipe, plastic pipe) incomparable. 1、优良的耐水、耐腐蚀性能： 1. Excellent water resistance and corrosion resistance: 管道内衬层科学合理的树脂选型和工艺铺层设计，确保了管道具有优良的防水、防渗、耐化学腐蚀性能。 The scientific and reasonable resin selection and process lay up design of the pipeline lining ensure that the pipeline has excellent waterproof, anti-seepage and chemical corrosion resistance. 2、水力特性优良、节省能耗、无二次污染 2, excellent hydraulic characteristics, energy saving and no two pollution. 内壁光滑，提高输送能力 The inner wall is smooth and the transport capacity is improved. 玻璃钢夹砂管内壁粗糙度系数只有0.0084，而钢管为0.04，混凝土管为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20-30%。 The roughness coefficient of the inner wall of the FRP tube is only 0.0084, while the steel pipe is 0.04, the concrete pipe is 0.014, the cast iron pipe is 0.013. Therefore, the glass tube can significantly reduce the loss of the fluid pressure along the path and improve the transport capacity of 20-30%. 减小口径，节约一次性投资 Reduce the caliber and save the one-time investment 在输送能力相同时，工程可降低1-2个管径等级选用玻璃钢夹砂管道，从而降低一次性的工程投资。 At the same time of conveying capacity, the project can reduce the diameter of 1-2 pipes to choose FRP pipes, thereby reducing the one-time investment. 节约运行费用 Save operation cost 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，还可以缩短泵送时间，减少长期运行费用。 With the same inner diameter pipe, the FRP pipe can reduce the pressure loss, save the pump cost, shorten the pumping time and reduce the long run cost. 防污抗蛀、无二次污染。 Antifouling, anti moth, and no two pollution. 玻璃钢夹砂管道的内表面洁净光滑，不会被海洋或污水中的甲贝、菌类等微生物站污蛀附，以致增大糙率、减少过水断面，增加维护费用。不会对水质或其它介质产生二次污染。 The inner surface of the FRP pipe grit pipe is clean and smooth, and it will not be contaminated by the microbes such as shellfish and fungus in the sea or sewage, so as to increase the roughness, reduce the cross section of water and increase the maintenance cost. There will be no two pollution to water quality or other media. 3、力学性能好、比强度高 3. Good mechanical properties and high specific strength 管道的拉伸强度低于钢，高于球墨铸铁管和混凝土管，而比强度大约是钢管的3倍，球墨铸铁管的10倍，混凝土管的25倍。管道的拉伸强度≥320 Mpa， 抗冲击性能：落锤重量1.5kg在冲击高度1600mm下不损坏。 The tensile strength of the pipe is lower than that of the steel, which is higher than that of the ductile cast iron pipe and the concrete tube, and the specific strength is about 3 times that of the steel pipe, 10 times the ductile cast iron pipe and 25 times the concrete pipe. The tensile strength of the pipeline is more than 320 Mpa, and the impact resistance is: the weight of drop weight 1.5kg is not damaged under the impact height 1600mm. 4、优良的耐温性能 4, excellent temperature resistance performance 普通玻璃钢夹砂管道的使用温度一般为-40-70℃，若选用耐温树脂，玻璃钢夹砂管道可以在120℃高温条件下长期运行，并保持良好的力学性能。 The temperature of ordinary FRP sand pipe is -40-70 C. If the temperature resistant resin is selected, the FRP sand pipe can run at 120 C for a long time and maintain good mechanical properties.
