PE pipes are still commonly used in our daily lives,but many users are worried about the storage of the pipes in winter,fearing that they may freeze.It should be noted that PE pipe fittings do not need to be frost resistant because PPR is a type of water that will freeze when the water drops below zero,increasing the volume of ice and causing the steel pipe to crack.Therefore,it is meaningless to say whether PE pipe fittings are frost resistant or not!The key is that the water pipes need to be antifreeze!Outdoor water pipes should be insulated while maintaining water circulation in the pipes to prevent freezing!As long as it is a genuine PE pipe,it will definitely not freeze,because the characteristic of PPR raw materials is low-temperature brittleness-it will become brittle below 4 degrees Celsius,and its ability to resist external forces will begin to decline.
If other raw materials are added to change this characteristic,it will seriously affect the temperature resistance,pressure resistance,and aging resistance of the pipeline.So the so-called antifreeze pipe is just a definition of what truly needs to be antifreeze,which is to take good measures to keep outdoor water pipes warm.The misconceptions about the frost resistance of PE pipes have been introduced quite clearly above.If you want to learn more about pipe materials,you can continue to follow our website updates.
