The working principle and working process of high-pressure high-temperature corrugated expansion joint High-pressure high-temperature corrugated expansion joint is an important component used to connect pipelines, and its working principle and working process are as follows:
Working principle: The working principle of high-pressure and high-temperature corrugated expansion joint is mainly to use the elastic deformation of the metal bellows to compensate for the thermal expansion and contraction and vibration of the pipeline, so as to eliminate the stress of the pipeline and protect the safe operation of the pipeline system.
Working process:1Pre-compression: During installation, the corrugated expansion joint is compressed to a certain length first, so that there is enough elastic deformation space inside it.
2.Compensate for the thermal expansion and contraction of the pipeline: When the pipeline is heated or cold, the metal bellows of the corrugated expansion joint will produce elastic deformation, absorb the displacement and deformation of the pipeline, and thus protect the pipeline system from damage.
3.Absorb pipeline vibration: When the pipeline is vibrate, the corrugated expansion joint can absorb the vibration energy and reduce the impact of pipeline vibration on the pipeline system.
4.Sealing and connection: The corrugated expansion joint also has the function of sealing and connection, which can ensure the tightness and connection strength of the pipeline system.
In a word, high-pressure and high-temperature corrugated expansion joint is an important pipeline connection component, and its working principle and working process involve many aspects, such as the characteristics of metal materials, structural design, manufacturing process, etc. Only by understanding its working principle and working process can we better use and maintain this component and ensure the safe operation of the pipeline system.
