PVC给水管是用来做给水用的，是用于供给生活饮用的水管，相对于排水管的要求要高些，除了物性方面达到要求外，如材质一般要求PVC新料，同时要求环保型，即不会对储存在管里的水释放有害物质，这一点至关重要。PVC给水管也有部分用于农田灌溉，与排水管最大的区别就是需要能承受压力，如果是给水工程上还需要有卫生指标，无毒无污染等检测指标。目前PVC给水管的市场份额在缩小，被质量性能更为优越的PE管材所取代。

PVC water supply pipe is used for water supply, is used for drinking water supply pipe, relative to the requirements of higher drainage pipe, in addition to physical properties to meet the requirements, such as the general requirements of PVC materials, and environmental protection, that is, will not release harmful substances to the water stored in the pipe, this is crucial. PVC water supply pipe is also partly used for farmland irrigation, and the biggest difference between the drainage pipe and the need to be able to withstand pressure, if the water supply project also needs to have sanitary indicators, non-toxic and pollution-free detection indicators. At present, the market share of PVC water supply pipe is shrinking and replaced by PE pipe with superior quality and performance.

PVC给水管优点：

PVC advantages of 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, handling and handling convenience: less density, handling, loading and unloading, construction convenience.

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: with excellent acid, alkali, corrosion resistance, suitable for the use of the chemical industry.

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. Low fluid resistance: the inner wall of the pipe is smooth, its roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network and reduces the operating costs 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, the mechanical strength is large: the pipe has good pressure resistance, impact resistance and tensile strength.

5、施工简易：管道连接施工迅速容易，施工铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件工程费低廉。

5. Simple construction: pipeline connection construction is quick and easy, and 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, convenient transportation and construction, 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。
