  • Detail

In the current building materials market, the price of PPR water pipes varies from high to low. The important factor affecting the uneven price is the quality of products. For example, in terms of raw material selection, some unknown brand or non brand PPR tubes with low sales prices are mostly made of recycled waste plastics, which are very cheap. However, the PPR water pipe made from this has certain toxicity, and there will be peculiar smell and black smoke during hot-melt connection. Long term use of it to transport drinking water will seriously damage people's health. Therefore, consumers must polish their eyes when shopping

1. Appearance: the high-quality pipes are made of 100% imported PPR raw materials, with smooth appearance, complete marks, and anti-counterfeiting marks on the accessories

2. Toughness: the good PPR pipes have good toughness, which can be easily bent into a circle without breaking, and the low-quality pipes are brittle, which will break as soon as they are bent

3. Thermal expansion and cold contraction: the good water pipes can still maintain hardness under the water temperature of 90 degrees, and the low-quality pipes will be softened under the water temperature of 60 degrees

4 Service life: the warranty of high-quality products is 50 years, and the warranty of low-quality products is only 5-6 years

ppr water pipes. The most common problem is water leakage. In addition to buying high-quality water pipes, installation specifications are also very important:

1. When using PPR pipe fittings with metal threads, you must use enough sealing tape to avoid water leakage at the threads

2. Do not tighten the pipe fittings too tightly to avoid cracks leading to water leakage

3. It is best to cut off the 4-5 cm end of the pipe

4 During winter construction, it is necessary to avoid stepping on, knocking, collision and throwing

5. After installation, the pressure test must be carried out. The pressure test time is 30 minutes, and the pressure drop is not more than 0.05Mpa within 30 seconds under the test pressure. When it is reduced to the working pressure for inspection, there is no leakage

6. The water pipe is best to go on the top, which is convenient for maintenance. If it goes underground, it is difficult to find water leakage and inconvenient for maintenance
