PPR管和PVC管的区别可以以管径的粗细为依据，但是这种鉴别的要领就必要经历了。首先对管子的环境都要熟习，少要有印象。这样的话时间长了看到管子就知道其规格是多大的了。
The difference between PPR pipe and PVC pipe can be based on the thickness of pipe diameter， but the essentials of this identification must be experienced. First of all， we should be familiar with the environment of the pipe， and have less impression. In this way， after a long time， you can see the size of the pipe.
给排水管的支吊架，有的施工人员为了节省费用，ppr给水管材，选择的型钢偏小，布置的数量没达到要求，或者布置的位置不合理。解决办法：在横管三通和弯头附近的地方一般要设置支吊架（此处一般受水流冲击力大些）。另外，对于upvc管而言，横管吊架设置的间距和它的dn直径相同，长宁区ppr管材，比如dn40的管吊架间距就为40cm。
For the supports and hangers of water supply and drainage pipes， some workers choose small parts steel in order to save costs，管材ppr， the number of layout does not meet the requirements， or the location of layout is unreasonable. Solution: the support and hanger should be set near the cross pipe tee and elbow (the impact force of water flow is greater here). In addition， for UPVC pipe， the spacing of horizontal pipe hanger is the same as its DN diameter， for example， the spacing of Dn40 pipe hanger is 40cm.
ppr管若装在地下车库
地下车库的电气预埋前结合风管、管道图纸，避免灯具与风管和管道重叠，造成后期灯具安装时敷设明线，增加造价及影响美观。
车库车库内有桥架，但过梁较大。局部桥架过梁时可采取梁中预埋钢制套管（套管的直径不宜过大），这样避免桥架从梁下上翻，影响车库的净高。
If PPR pipe is installed in underground garage
Before the electrical pre burying of underground garage， the air duct and pipeline drawings shall be combined to avoid the overlapping of lamps with air duct and pipeline， resulting in the laying of open lines during the later installation of lamps，PPR管材， increasing the cost and affecting the appearance.
There is a bridge in the garage， but the lintel is large. The steel casing (the diameter of the casing should not be too large) can be embedded in the beam when the local bridge is over the beam， so as to prevent the bridge from turning up from under the beam and affecting the net height of the garage.
