| Q: My family renovated construction team that PP-R pipe pressure test as long as two hours, two hours did not drop on it. I checked some of the decoration found no basis for acceptance criteria. He is right, right?
A: Many people regard this pipe PP-R pipe are not familiar with that of traditional aluminum, copper tubing and so it is better, in fact PP-R pipe is a high cost-effective pipe, so a home-improvement of water Tube material of choice for transformation. Its interface with hot-melt technology, fully integrated between the pipes together, so once installed pressure test will not be re-water leakage, high reliability. But this is not to say there were no defects PP-R pipe, its temperature resistance, a less pressure these, long-term working temperature should not exceed 70 ℃; Each length is limited, and can not bend construction, long distance, or if the pipeline the corner more than they should be used in the construction of a large number of joints; pipe fittings are cheaper but the price is relatively high. Regular PP-R pipe pressure test process: in the pipeline to connect 24 hours after the pressure test, the pressure to reach 7-8 kg. Because the daily water consumption, pressure is 3-4 kg. Then look at the pace of decline in pressure gauge, and then check for any leaks in pipe joints. PPR pipe test time of 3 hours, but the actual construction, if no pressure drop within 2 hours and no leakage could be as qualified, because the welding weld leakage rarely occurs, unless the welding was very sloppy. Feng currently on the market the previous day, love Kang - Poly, Rifkind, Wei Xing, golden horns, together brands such as plastic PP-R pipe good price, quality and after-sales service more secure. In addition, the previous period appears on the domestic market, PP-C pipe, pipe fittings, the installation method and the PP-R line. In the international standard, polypropylene, hot and cold water pipes sub-PP-H, PP-B, PP-R 3 kinds, there is no PP-C. On the market is indeed PP-C Pipe PP-B pipe, is a kind of hot and cold water pipes, the price is cheaper, but its heat resistance, pressure resistance and a great gap between PP-R. Structure size on the market in line with the PP-R pipe PP-C, its use is much lower and can not be confused with the use of PPR pipe, but can not be in determining the conditions of use after the PP-C Pipe PP-R pipe replacement.
