PPR water supply pipe is a kind of water supply pipe made from PPR. PPR is a kind of environmental protection material with the characteristics of health， sanitation and environmental protection. With the development of society and people's attention to environmental protection， PPR raw material has become a new product of UPVC water supply pipe， aluminum plastic pipe， PE pipe， PEX pipe and pert pipe， and has become a new favorite of the contemporary home decoration building materials pipeline industry.

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，PVC排水管加工，造成后期灯具安装时敷设明线，密云PVC排水管，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，PVC排水管生产， 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， 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.

目前，法兰连接中大的问题主要是法兰本身不合格和法兰连接不合格。

现在市场上销售的一些法兰存在的质量问题有：

①法兰的钢材不合格，耐压强度较低，在使用若干个月或若干个年后，出现渗水。

②法兰的螺栓孔外缘距法兰的边缘太小，小于5mm，在螺栓紧固时，易使法兰边缘。

At present， the major problems in flange connection are the unqualified flange itself and the flange connection is unqualified.

Some of the quality problems of the flange sold in the market are as follows:

① The flange steel is unqualified and the pressure resistance is low. After several months or years of use， water seepage occurs.

② The outer edge of bolt hole of flange is too small from the flange edge， less than 5mm. When the bolts are tightened， it is easy to make the flange edge.
