Nowadays, the service life of ppr water pipes on the market is often 50 years, but why are there still many water pipes leaking and bursting? Let’s take a look at the following reasons.
First of all, the ppr pipe is not tightly connected when it is hot-melt connection. The most direct reason for water leakage is that the connection is not firm, such as the temperature of hot-melt is not reached, the time of hot-melt is not enough, etc. Water pipes will leak after a period of use.
Secondly, there is the problem of water pipe bursting. For example, the water pipe itself has hidden cracks, and even under normal working pressure, a large area of rupture will occur in a short period of time. There is also the quality of the pipes themselves, and the quality of pipes produced by some unscrupulous manufacturers does not match the publicity.
Then, it is also a common situation that the ppr water pipe burst due to excessive pressure. For example, the pressure caused by unintentionally pressing a heavy object on the water pipe is too large, and the water pipe bursts after a period of time. In addition, the pressure coefficient of the water pipe is not selected well. The higher the floor is, the smaller the pressure of the water pipe is. The corresponding pressure-resistant water pipe must be selected according to the floor. If the pressure-resistant coefficient is small, it is easy to burst the pipe during use.
Finally, there is the problem of freezing when the climate is cold. Some outdoor exposed water pipes are not well insulated, and long-term thermal expansion and contraction will also cause the water pipes to burst.
