1、Portable, PVC material specific weight is only 1/10 of cast iron, easy to transport and install, low cost;

2、 Good chemical resistance performance, UPVC has good performance of anti acid and alkaline;

3、Insulation: UPVC can neither conduct electricity and nor be electrolyzed, or be eroded by electric current, no need to reprocess;

4、 Anti-flaming, self-extinguished 3 seconds after moved away from the fire, no worry about fire protection;

5、Easy to install: easy to cut and connect, it prove to be safe to connect it by PVC glue, easy to operate;

6、 Durability, good whether resistance, no corrosion by bacterial;

7、Low fluid flow resistance, smooth inside surface, little low of fluid flow speed, no crust on inside surface, easy to maintain, low maintenance cost.

安装步骤

排水管安装属于隐蔽工程，完工之后就很难整改，因此在安装过程中应特别注意。那么，PVC-U排水管该怎么安装呢?今天给大家分享PVC-U排水管的安装步骤与安装方法，供大家排水管安装参考。 

1、锯管及坡口   

A:锯管工具宜采用细齿锯，割刀和割管机等工具，切口应平整并垂直于管身，断面处不得有任何变形。   

B:插口处可用中号板锉锉成15°-30°坡口，坡口厚度为管壁厚度的1/3-1/2，长度一般不小于3mm，坡口完成后应将残屑清除干净。 

2、管端插承口深度   

锯管长度根据实测，并结合各连接管件的尺寸逐层确定。 

3、胶粘剂涂刷  

建议选用我公司的PVC专用胶粘剂，用随胶粘剂配送的小刷子蘸取胶粘剂，涂刷管材与管件的接合面，应轴向涂刷，动作迅速涂抹均匀，且涂刷的胶粘剂要适量，不得漏涂或涂抹过厚。冬季施工时尤须注意，应先涂承口后涂插口。 

4、承插接口的连接   

承插口涂刷胶粘剂后，应立即找正方向将管子插入承口，使管端插入深度符合所画标记，并保证承插接口的直度和接口位置正确，还应保持2-3分钟，防止接口滑脱，预制管端节点间误差应不大于5mm。   

5、承插接口的养护 

承插接口接插完毕后，应将挤出的胶粘剂用棉纱或干布蘸清洁剂擦拭干净。根据胶粘剂的性能和气候条件静置接口固化为止。冬季或雨季施工时固化时间应适当延长。
