1. It is best to find a professional company to install PP-R pipe, no matter how luxurious and upscale your decoration, if you are not willing to use money in this area, it is not worthwhile. Frequent crushing or blockage of pipelines will result in tens, hundreds, even incalculable consequences for the prices of the water pipes themselves.
PP pipe and fitting is made by material polypropylene, it can be used for both water system and industrial application, PP Pipe Fitting has good mechanical properties, good chemical properties, good heat resistance, good electrical insulation, non-toxic.
Ningbo RMI Plastic Co.,Ltd produce PP pipe fitting, PP-H pipe fitting and PP-GF pipe fittings according to standard DIN 8077/8078, pressure rate PN10, SDR11 and PN6, SDR17.6 size from 20mm to 500mm.
PP pipe and fitting includes: PP coupling, PP elbow, PP tee, PP flange, PP reducer, PP end cap, PP union, it is suitable for water supply, water treatment, chemical industrial, steel factory acid pickling system, chlor alkali industry, pharmaceutical industry, etc.

2, must be pressurized after installation. The pressurization test is generally performed at 1.5 times the water pressure, and there should be no water leakage during the test.
3. A simple test method without pressurization is not completely feasible.
1) Close the water main valve. (ie the water switch in front of the water meter)
2) Open the faucet inside the room for 20 minutes, make sure that no water is dripped and then close all taps.
3) Close the water inlet switch of the water storage device such as the toilet tank and the washing machine.
4) Open the main valve of the water pipe.
5) Check whether the water meter is moving 20 minutes after opening the main valve, including slow walking.
If there is movement, it is leaking. If you don't move around, it may be okay. (If there is a problem with the water meter or micro-permeability of the water pipe, it may be difficult to determine.) Therefore, it is recommended that a hydrostatic test be conducted after the completion of the construction. Generally, 8 kg of pressure is applied for 20-30 minutes. (It's best to see for yourself)
4, the direction of the water pipe: It is recommended that the pipe is safest. The main reason is that most of the waterway reforms go through dark pipes, while the water is characterized by low water flow. If the pipeline goes underground, it is difficult to find water leakage in time. Only when the water is diffused into the Jinshan or the floor is deformed and leaked downstairs, water leakage will be discovered, and it is difficult to detect the leak due to the buried pipe. At this time, the huge losses are even more irreversible. They have even seriously affected friendly neighborhood relations; if the water pipes are at the top, the cost of water reform may be higher, but as a long-term investment, it is worthwhile. When the water pipe is at the top, even if it leaks, it can be discovered in time, it is easy to overhaul, and the loss is small.
