Where should expansion joints be protected?
Expansion joint is an important equipment used in pipeline system. Its main function is to discharge moisture and gas from the pipeline to ensure the stability and normal operation of the pipeline system. However, in the process of using expansion joints, expansion joints are also subject to some wear and tear and damage. Therefore, in order to ensure the service life of expansion joints, we should choose the correct protection position. Generally speaking, the expansion joint should be protected at the outlet of the pipeline. This is because at the outlet of the pipeline, there is often a collection of water and gas, which can lead to wear and damage of the expansion joint. Also, at the outlet, there may be excessive pressure, which can also cause damage to the expansion joint.
 
In addition, in pipelines, expansion joints should also be affected by influences from outside, such as temperature changes, pressure changes, etc. These external influences can also affect the service life of expansion joints.
 
Therefore, in order to ensure the service life of expansion joints, we should choose the right protection locations and take appropriate protection measures at these locations. For example, the compensation device of the expansion joint should be installed at the outlet of the pipeline to protect the expansion joint from the abrasion of water and gas; meanwhile, we can protect the expansion joint by replacing the worn part of the expansion joint in the pipeline.
 
Expansion joints play a very important role in the pipeline system, and their use can make the pipeline system more stable and efficient. Therefore, in order to ensure the service life of expansion joints, we need to choose the right protection locations and take appropriate protection measures in these locations.
