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，PVC管业厂家，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.
ppr管在电气部分：
部分开关、插座被后续的给、排水管道、厨卫风道等掩盖，所以施工前必须结合土建预留预埋，考虑到位。

相对于其他PP管材，PP-R管材的突出优点是既改善了PP-H的低温脆性，又在较高温度下(60℃)具有良好的耐长期水压能力，特别是用于热水管使 用时，长期强度均较PP-H和PP-B好。
Compared with other PP pipes， the outstanding advantage of PP-R pipe is that it not only improves the low temperature brittleness of pp-h， but also has good long-term water pressure resistance at higher temperature (60 ℃). Especially when it is used for hot water pipe， the long-term strength is better than pp-h and pp-b.
