PPR Pipe Product Knowledge

Q:What are the specifications of the water pipes commonly used in the home?

A:For PP-R water pipes, in the home improvement building materials market, PP-R water pipes with an outer diameter of 20mm and an outer diameter of 25mm are usually most commonly sold. These two outer diameter water pipes are the most used water pipe specifications in home decoration. Occasionally, a PPR water pipe with an outer diameter of 32mm is used in the household water pipe, which is also the size specification often used in the case of a relatively large apartment, such as villa decoration.

Q:Why is there moss growing in the PPR water pipe?

A: The phenomenon of "moss" growing on the inner wall of the PPR water pipe is not a common phenomenon of all PP-R water pipes, but the PP-R water pipe manufacturing process did not follow the relevant standards, and the shading performance of the manufactured water pipes did not meet the standard. Moreover, the installation standards were not strictly implemented during installation, and the PP-R water pipe was directly exposed. A good PP-R pipe can completely avoid this problem.

Q:How long can PPR water pipes be used normally?

A: According to the material properties of random copolymerized polypropylene, it normally takes long-term durability according to standards at a temperature of 60°C to appear the inflection point of mechanical properties. Under normal circumstances, even in summer, the temperature of the water transported by the PP-R water pipe is only about 20°C, but under the condition of 20°C, after using it for about long-term durability according to standards, the ring stress of the material can always be kept above 10Mpa, which is enough pressure. Meet the daily water pressure. Therefore, the PP-R material can basically guarantee that the PP-R water pipe can be used for more than long-term durability according to standards under normal conditions.

Q:Why are PPR water pipes colorful?

A: The pure PP-R raw material is actually colorless and transparent, without any color, so it will be easier to cause algae and bacteria to grow in the water pipe because it will not cover the light after it is made into the water pipe, which will pollute the water quality. It will accelerate the aging of the water pipe and affect the service life of the PP-R water pipe. Therefore, according to the requirements of national standards, in the production of 1PP-R water pipes, color masterbatch must be added to make the water pipes obtain good shading performance.

Q:Water pipe welding is not reliable, what may be the reason?

A: It may be that the temperature of the welding machine is too high: the temperature for welding PP-R should be 260°C, preferably not more than 270°C. Excessive temperature will cause the PP-R material to become too thin and soft, or even partially carbonized1, resulting in Welding problem. In addition, it is also possible that the welding tip is aging or the size of the tip is not standard. So don't be sloppy when welding.

Q:What PPR pipelines are recommended？

A: IFAN PP-R standard pipe not only has the advantages of light weight, corrosion resistance, no scaling and long service life, but also has good hygienic performance, better heat resistance and longer service life. It has the advantages of longevity, low thermal conductivity, thermal insulation and energy saving. It is a veritable green building material.
