PVC排水管优点
Advantages of PVC drainage pipe
1、PVC排水管的表面硬度和抗拉强度优异，且管道安全系数极高。
1. The surface hardness and tensile strength of PVC drainage pipe are excellent, and the pipeline safety factor is very high.
2、PVC排水管的抗老化性好，通常它的正常使用寿命可达50年以上。
2, PVC drainage pipe has good aging resistance, and its normal service life can usually be more than 50 years.
3、PVC排水管对无机酸、碱、盐类等物质有着非常优良的耐腐蚀性能，所以较适用于工业污水排放及输送。
3. PVC drainage pipe has excellent corrosion resistance to inorganic acid, alkali, salt and other substances, so it is suitable for industrial sewage discharge and transportation.
4、PVC排水管摩阻系数小，水流顺畅，不易堵塞，养护工作量少，且氧指数高，具有自熄性。
4. PVC drainage pipe has small friction coefficient, smooth water flow, not easy to block, less maintenance work, high oxygen index and self extinguishing.
5、PVC排水管道线膨胀系数小，为0.07mm/℃，受温度影响变形量小。导 热系数和弹性模量小，抗冰冻性优异。
5. The linear expansion coefficient of PVC drainage pipe is 0.07mm / ℃, and the deformation is small due to temperature influence. The thermal conductivity and elastic modulus are small, and the frost resistance is excellent.
6、PVC排水管连接可用粘接方法，施工简单，操作方便，安装效率高。
6. PVC drainage pipe can be connected by bonding method, which is simple in construction, convenient in operation and high in installation efficiency.
