夹砂玻璃钢管具有光滑的内表面,适用于大口径(≥φ500mm)输水管道的特点,磨阻系数小,水力流体特性好,而且管径越大其优势越明显。反之,在管道输送流量相同的情况下,工程上可以采用内径较小的夹砂玻璃钢管代替,从而降低了一次性的工程投入。夹砂玻璃钢管道在输水过程中与其它的管材相比,可以大大减少压头损失,节省泵的功率和能源。
Sand filled FRP pipe has smooth inner surface and is suitable for large diameter (≥) φ 500mm) water transmission pipeline has the characteristics of small wear resistance coefficient and good hydraulic fluid characteristics, and the larger the pipe diameter, the more obvious its advantages. On the contrary, when the pipeline transportation flow is the same, the sand filled FRP pipe with smaller inner diameter can be used in the project, so as to reduce the one-time project investment. Compared with other pipes, sand mixed FRP pipes can greatly reduce head loss and save pump power and energy.
【使用寿命长、安全可靠】
[long service life, safe and reliable]
玻璃钢夹砂管设计安全系数高。据实验室的模拟试验表:一般给水、排水夹砂玻璃钢管的寿命可达50年以上,是钢管和混凝土管的2倍。对于腐蚀性较强的介质,其使用寿命远高于钢管等。
FRP sand pipe is designed with high safety factor. According to the laboratory simulation test table, the service life of general water supply and drainage sand mixed FRP pipe can reach more than 50 years, twice that of steel pipe and concrete pipe. For highly corrosive media, its service life is much longer than that of steel pipe.
