1. Why are the colors of PPR pipes different?
This is caused by the different color masterbatches used in the production of raw material . The color does not represent the quality of PPR pipes.
2. How does PPR water pipe distinguish between cold water pipe and hot water pipe?
PPR pipes are divided into cold water pipes and hot water pipes. However, hot water pipes are commonly used in home improvement to replace cold water pipes, which has achieved higher safety. Cold water pipes and hot water pipes are actually distinguished according to the pressure level. For easy identification, many brands have a blue line on the cold water pipe and a red line on the hot water pipe.
3. How to divide the specifications of PPR water pipes?
There are two main indicators:
The diameter of the PPR pipe (here refers to the outer diameter of the water pipe) can be from 16mm to 160mm, and the main ones used in home decoration are 20mm and 25mm, of which 25mm use more. More. Wall thicknesses use 2.8mm and 3.4mm normally.
4. How to judge the quality of PPR pipes?
Appearance: The high-quality pipe has a smooth appearance, complete identification, and also printed the brand name on it.
Toughness: Good quality PPR pipe has good toughness and can be easily bent into a circle without breaking, while inferior quality pipe is more brittle and breaks immediately. But PPR is cold and brittle. In winter, good toughness is not necessarily a good water pipe.
Thermal expansion and contraction: good water pipes can still maintain good strength at high water temperature, while poor quality pipes are softened at 60 degrees water temperature.
