PVC管主要包括PVC排水管，PVC给水管，PVC电工套管等，当然还有新型材料如PVC-M管、PVC-O管等，我们日常使用的基本上是PVC排水管和PVC给水管，那么这两种管材在用途和优势等方面具体哪些区别呢，今天就为大家介绍一下。

PVC pipes include PVC pipes, PVC pipes, PVC bushing, as well as new materials such as PVC-M pipe, PVC-O pipe, our daily use is basically PVC pipes and PVC pipes, then the two pipes in use and advantages of what difference does it make for everyone today introduce.

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 use, is used to supply drinking water, relative to the drainage pipe requirements should be higher, in addition to meet the requirements of the general requirements, such as material PVC new material, at the same time, the requirements of environmental protection, that is not stored in the water in the tube to release harmful substances, this point critical. PVC water supply pipe is also partly used for farmland irrigation. The biggest difference between the water pipe and the drainage pipe is that it can withstand pressure. If it is a water supply project, there are also health indicators, non-toxic, pollution-free and other indicators. At present, the market share of PVC water supply pipe is narrowing, and is replaced by PE pipe with better quality and performance.

PVC给水管优点：

PVC benefits of water supply:

1.质轻，搬运装卸便利：密度较小，搬运、装卸、施工方便。

1. light, handling convenient handling: small density, handling, loading and unloading, construction is convenient.

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 resistance, alkali resistance, corrosion resistance, for the use of 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 inner wall of the pipe is smooth, the roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic condition of the pipe network and reduces the operation 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: 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，施工工程费低廉。

5. the construction is simple: the pipe connection construction is quick and easy, and the cost of construction works 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 is convenient, 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: it is confirmed by the dissolution test that it does not affect the water quality and is suitable for large area application.

PVC排水管是用来排水用的，主要用于房地产项目上的排水、雨水、小区排水等，对管材本身没有压力和卫生指标要求，区别管材的质量好坏主要看韧性、拉伸等。

PVC drainage pipe is used for draining. It is mainly used for drainage, rainwater and drainage in residential area. There are no pressure and hygienic index requirements for pipes. The quality difference between pipes is mainly about toughness and tensile strength.
