Question 1:

Is the PPR tube that is not cracked a good PPR pipe?

The embrittlement temperature of PPR is 0 °C. Because of its low temperature brittleness, it is easy to be cracked under low temperature conditions. This is the inherent property of PPR. The PPR pipes that are not cracked on the market are all pseudo-PPB pipes, mainly Because the low temperature resistance of PPB reaches -10 °C, the performance is slightly better than PPR, but the high temperature resistance of PPB pipe is poor, and the explosive pipe is used for a long time. It is not recommended to be used in the home supply water supply pipe system. The durability of the pipe is mainly determined by the long-term creep resistance of the pipe, especially the high temperature and pressure resistance of the pipe, so the impact performance is not a standard for measuring the durability of the PPR pipe.

Question 2:

Sometimes the smell in the water is released by the PPR pipe?

The PPR tube has only carbon and hydrogen elements, contains no other elements, and is less likely to contain toxic or odorous impurities. It is very likely that the odor is adhered to organic substances such as paint, glue or oil on the pipe and penetrates into the pipe. It is recommended that PPR avoid contact with glue/paint during the installation process and protect the pipeline after the pipeline is installed.

Question 3:

Is the green water in the green tube caused by the fading of the pipe?

P PPR pipes of various colors are integrally extruded and extruded with PPR base material and various toners. There is no peeling or precipitation appearance. Green water is actually moss or green algae, mainly due to the long-term non-flow of water in the pipeline, coupled with the installation of pipes, resulting in rapid propagation of algae in the pipeline under photosynthesis. It is recommended to use dark opaque tubing for home improvement.

Question 4:

The white PPR tube is hygienic, and the gray PPR pipe is unsanitary?

PPR pipes of various colors are organically extruded from PPR base materials and toners of various colors. The water supply PPR pipes must be marketed and sold, and must meet the water supply sanitation license required by the national standard, so there is no white PPR pipe. It is hygienic and clean, while gray, green or other color PPR tubes are unsanitary.

Question 5:

All brands use PPR materials. Can PPR pipes and fittings from different manufacturers be interconnected?

In fact, this is also a very common misunderstanding. Although all brands are selling PPR pipes and fittings, the production process and welding process of different raw materials will be slightly different due to the different PPR raw materials selected by each brand, in order to ensure the reliability of the pipeline system. Sex, it is recommended to use the same brand of PPR pipe and pipe interconnect.
