Function of high-pressure steel expansion joint:
Steel expansion joints, also known as expansion joints, expansion joints, and compensators, are divided into several types: corrugated compensators, sleeve compensators, rotary compensators, square natural compensators, etc. Among them, corrugated compensators are more commonly used, mainly to ensure the safe operation of pipelines. Steel expansion joints have the following functions:
1. Compensate for axial, transverse, and angular thermal deformation of the absorption pipeline.
2. Absorb equipment vibration and reduce the impact of equipment vibration on pipelines.
3. Absorb the deformation of pipelines caused by earthquakes and subsidence.
