PPR hot and cold water pipes are usually used in kitchens and bathrooms when decorating families. How to select safe and high-quality hot and cold water pipes? What are the key points of installation?
PPR pipe, why is there a difference between cold and hot?
According to the national standard GB/T18742.2 PPR pipes, PPR cold and hot water pipes have five series: S5, S4, S3.2, S2.5 and S2. In the above five series, the bearing pressure shows an increasing rule, that is, the smaller the S value, the thicker the wall thickness, and the greater the bearing pressure.
Generally speaking, PPR cold water pipes usually use S values less than or equal to 5, and hot water pipes use S values less than or greater than 3.2.
What are the hazards of improper installation of hot and cold water pipes?
PPR hot and cold water pipes must be installed in a standard way. First of all, PPR cold water pipe cannot be used to replace hot water pipe. Its pressure resistance and temperature resistance are far inferior to hot water pipes. Working under hot water for a long time is easy to cause aging damage, which will lead to pipe wall fracture and water leakage.
In addition, the installation shall be "hot on the left and cold on the right", and the parallel spacing between hot and cold water pipes shall not be less than 20cm, otherwise it will cause heat loss of hot water in the hot water pipe and affect the use of hot water.
After reading the above, do you think the selection and installation of PPR hot and cold water pipes are a little complicated? Is there a better solution?
Large wall thickness, more durable
Compare and understand the gap! IFAN PPR pipe is temperature resistant and pressure resistant, which is applicable to both cold and hot water. You don't have to worry about how to select PPR cold and hot water pipes any more.
