玻璃钢管道是一种轻质、高强、耐腐蚀的非金属管道。它是具有树脂基体重的玻璃纤维按工艺要求逐层缠绕在旋转的芯模上，并在纤维之间远距离均匀地铺上石英砂作为夹砂层。其管壁结构合理先进，能充分发挥材料的作用，在满足使用强度的前题下，提高了钢度，保证了产品的稳定性和可靠性。玻璃钢夹砂管以其优异的耐化学腐蚀、轻质高强，不结垢，抗震性强，与普通钢管比较使用寿命长，综合造价低，安装快捷，安全可靠等优点，被广大用户所接受。

FRP pipe is a lightweight, high strength, corrosion resistant nonmetal pipe. It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer. The pipe wall structure reasonable and advanced, can give full play to the role of material, to meet the premise of use strength, improve the rigidity, ensure the stability and reliability of the product. Glass fiber reinforced plastic sand pipe has excellent chemical resistance, light weight, high strength, no scaling and strong earthquake resistance. Compared with ordinary steel pipe, it has many advantages such as long service life, low comprehensive cost, quick installation, safety and reliability. It is accepted by users.

管道特性：

Pipeline characteristics:

（1）耐腐蚀性：化学惰性的材质，耐腐蚀性优异，并可根据输送介质选择不同的耐腐蚀管道。

(1) corrosion resistance: chemical inert material, excellent corrosion resistance, and can choose different corrosion resistant pipes according to the conveying medium.

（2）机械强度大：耐水压强度，耐外压强度和耐冲击强度均良好并可按要求的压力设计制造管道和管件。

(2) large mechanical strength: water pressure resistance, resistance to external pressure and impact strength are all good and can be designed and manufactured pipes and fittings according to the required pressure.

（3）温度适应性强：使用温度范围：大于-70摄氏度小于250摄氏度，冰冻介质下管道不裂。

(3) good temperature adaptability: use the temperature range: more than -70 degrees Celsius less than 250 degrees Celsius, freezing medium pipe is not cracked.

（4）流体阻力小：管道内壁光滑，粗糙系数0.0084,相同流量下,管径可予缩小。

(4) the fluid resistance is small: the inner wall of the pipe is smooth and the roughness coefficient is 0.0084. Under the same flow, the diameter of the pipe can be reduced.

（5）重量轻，寿命长：质轻，运输便利，施工费用低，无须维修，使用寿命长达50年以上。

(5) light weight, long life: light quality, convenient transportation, low construction cost, no maintenance, and service life for more than 50 years.

（6）保持水质：无毒，输送饮水用水，能保持长期水质卫生。

(6) to maintain water quality: non-toxic, transport water for drinking water, and maintain long-term water quality hygiene.
