PPR water pipes have been widely used in engineering and daily life, but many users still don't know much about PPR materials and products. If you want to use PPR pipe fittings correctly and improve the comfort of home life, you must have a clear understanding of them. Here, IFAN summarizes some of the questions frequently raised by users, and summarizes and explains them for everyone.
What is the difference between the specifications of PPR Water Pipes?
At present, the diameters of the PPR Water Pipes that we commonly see in the market are usually 25MM (commonly known as 6-point pipes) and 20MM (commonly known as 4-point pipes). Generally, the specification, wall thickness and other information of the pipe will be marked on the pipe wall, and the user can choose according to the information and actual needs.
What is the difference between PPR hot and cold Water Pipes?
The difference between hot and cold PPR Water pipes is also a question that is often talked about. On the pipe wall, the hot water pipe is generally marked with a red line, and the cold water pipe is marked with a blue line. Hot water pipes are thicker than cold water pipes, have better pressure and high temperature resistance, and have higher stability in high temperature environments, but they will be brittle and have a certain probability of damage under low temperature conditions; cold water pipes are the same as On the contrary, it has good toughness under low temperature conditions, but its strength is greatly reduced under high temperature conditions, and it is easy to deform. In non-extreme cases, hot water pipes can be used as cold water pipes, but cold water pipes cannot replace hot water pipes.
