玻璃鋼夾砂管性能特點(diǎn)

玻璃鋼夾砂管道是一種性能優(yōu)異的新型復(fù)合材料管材，它具有其它傳統(tǒng)管材（金屬管材、混凝土管材、塑料管材）無法比擬優(yōu)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、優(yōu)良的耐水、耐腐蝕性能： 1. Excellent water resistance and corrosion resistance: 管道內(nèi)襯層科學(xué)合理的樹脂選型和工藝鋪層設(shè)計(jì)，確保了管道具有優(yōu)良的防水、防滲、耐化學(xué)腐蝕性能。 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、水力特性優(yōu)良、節(jié)省能耗、無二次污染 2, excellent hydraulic characteristics, energy saving and no two pollution. 內(nèi)壁光滑，提高輸送能力 The inner wall is smooth and the transport capacity is improved. 玻璃鋼夾砂管內(nèi)壁粗糙度系數(shù)只有0.0084，而鋼管為0.04，混凝土管為0.014，鑄鐵管為0.013，因此，玻璃鋼管能顯著減少沿程的流體壓力損失，提高輸送能力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%. 減小口徑，節(jié)約一次性投資 Reduce the caliber and save the one-time investment 在輸送能力相同時(shí)，工程可降低1-2個(gè)管徑等級(jí)選用玻璃鋼夾砂管道，從而降低一次性的工程投資。 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. 節(jié)約運(yùn)行費(fèi)用 Save operation cost 采用同等內(nèi)徑的管道，玻璃鋼管道可比其他材質(zhì)管道減少壓頭損失，節(jié)省泵送費(fèi)用，還可以縮短泵送時(shí)間，減少長期運(yùn)行費(fèi)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、無二次污染。 Antifouling, anti moth, and no two pollution. 玻璃鋼夾砂管道的內(nèi)表面潔凈光滑，不會(huì)被海洋或污水中的甲貝、菌類等微生物站污蛀附，以致增大糙率、減少過水?dāng)嗝�，增加維護(hù)費(fèi)用。不會(huì)對(duì)水質(zhì)或其它介質(zhì)產(chǎn)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、力學(xué)性能好、比強(qiáng)度高 3. Good mechanical properties and high specific strength 管道的拉伸強(qiáng)度低于鋼，高于球墨鑄鐵管和混凝土管，而比強(qiáng)度大約是鋼管的3倍，球墨鑄鐵管的10倍，混凝土管的25倍。管道的拉伸強(qiáng)度≥320 Mpa， 抗沖擊性能：落錘重量1.5kg在沖擊高度1600mm下不損壞。 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、優(yōu)良的耐溫性能 4, excellent temperature resistance performance 普通玻璃鋼夾砂管道的使用溫度一般為-40-70℃，若選用耐溫樹脂，玻璃鋼夾砂管道可以在120℃高溫條件下長期運(yùn)行，并保持良好的力學(xué)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.
