PVC给水管优点：

Advantages of PVC water supply pipe:

1.质轻，搬运装卸便利：密度较小，搬运、装卸、施工方便。

1. light weight, convenient handling: low density, handling, loading and unloading, convenient construction.

2.耐腐蚀性优良：具有优异的耐酸、耐碱、耐腐蚀性，对于化学工业之用途甚为适合。

2. excellent corrosion resistance: excellent acid, alkali resistance, corrosion resistance, the use of the chemical industry is very suitable.

3.流体阻力小：管材内壁光滑，其粗糙系数仅为0.009，流体阻力小，有效地改善了管网的水力条件，减少了系统运行费用。

3. the fluid resistance is small: the pipe wall is smooth, the roughness coefficient is only 0.009, the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network, and reduces the operating cost of the system.

4.机械强度大：管材具有良好的耐压性能，抗冲击性能和抗拉伸强度性能。

4. mechanical strength: the tube has good pressure resistance, impact resistance and tensile strength performance.

5.施工简易：管道连接施工迅速容易，施工工程费低廉。

5. simple construction: pipe connection construction quickly and easily, the construction cost is low.

6.造价低廉：价格低，而且运输、施工方便，使用寿命长，因此总体造价低廉。

6. low cost: low price, and transportation, construction convenience, long service life, so the overall cost is low.

7.不影响水质：由溶解试验证实不影响水质，适宜大面积推广应用。

7. does not affect the water quality by dissolution test that does not affect the water quality, suitable for popularization and application in large area.
