During the installation of water pipes, the distribution of water pipes and pipes is relatively complicated, and it is inevitable that the pipes will turn or two pipes cross. In this case, we need a professional pipe fitting to solve this situation, which is our bridge bend. What is the function of crossing the bridge? When installed on the ground, when the pipeline is overlapped with the pipeline, it needs to be connected by a bridge to prevent the ground from being raised.
The bridge bend plays a transitional role, and the use of the bridge bend also has precautions. If you use it incorrectly, it will cause unnecessary losses, such as pipe burst!
We know that water pipes are divided into hot and cold water pipes. The wall of the hot water pipe is thicker, and the pressure bearing capacity of the two pipes is different. When the hot water pipe is subjected to excessive external force, it may be damaged, which is what we call an explosion. When installing hot and cold water, the bridge bend should be installed on the cold water pipe, and a hot water pipe should be placed on it. This is a standard practice. Why should the bridge bend be installed on the cold water pipe instead of the hot water pipe? PPR pipe: blue line for cold water pipe, red line for hot water pipe. Because the main material of PPR pipe is plastic, if it is melted on hot water, it will become soft and deformed when used for a long time, but it will not be used on cold water pipes.
Therefore, when it comes to thermal expansion and cold contraction, it is relatively reliable to fuse the bridge on the cold water pipe, which can increase the service life of the bridge.
