Most consumers don't understand the cold and brittleness of PPR pipes, and even think that this is a sign of "poor quality of PPR water pipes, and good PPR pipes will not break due to cold and brittleness". So is the real situation like this? How should we treat this phenomenon of PPR water pipes? IFAN will introduce to you the relevant knowledge about the cold and brittleness of PPR water pipes.
What is the cold brittleness of PPR pipe?
In the case of low temperature, especially in winter, the rigidity of the PPR pipe increases, while the flexibility decreases, showing that the overall pipe becomes brittle. This is the brittleness of PPR water pipes.
Is cold brittleness an indicator for judging the quality of PPR pipes?
Cold brittleness is an inherent property of the PPR pipe itself, and it has no necessary relationship with its quality. In order to attract customers, some merchants claim that their pipes cannot be broken, but this is definitely a misunderstanding.
In the specific process of using PPR water pipes, how can we avoid the damage caused by cold and brittleness to the water pipes?

After the concealed laying, the position of the pipe should be marked to avoid damage to the pipe by secondary decoration; the pipe is required to be stored in the warehouse and simple shed, and the stacking height should not exceed 1.5M; The PPR pipe has a certain cold and brittleness in the environment below 5°C. Be careful in winter construction, and use a sharp knife to cut slowly when cutting the pipe. For the installed pipes, do not press or knock them heavily, and if necessary, cover the parts that are vulnerable to external forces with protective materials; before performing hot-melt connections on the pipes, carefully check whether the pipes have been damaged.
