Similarities and differences between expansion joints and angle compensators
Release time:
2023-02-14
Angle compensators are generally made of low-alloy steel integrally formed corrugated metal bellows components to compensate for the offset and tensile strain caused by thermal expansion and contraction of the pipeline. Expansion joints generally use sealing rings. They have a sealing function and leave a gap between the pipe ends to compensate for the offset and tensile strain caused by thermal expansion and contraction of the pipeline.
Angle Compensator Generally, it uses low-alloy steel integrally formed metal bellows flexible components to compensate for the offset and tensile strain caused by thermal expansion and contraction of the pipeline. Expansion joints generally use sealing rings. They have a sealing function and leave a gap between the pipe ends to compensate for the offset and tensile strain caused by thermal expansion and contraction of the pipeline.
Expansion joints are also known as expansion joints, angle compensators, and expansion connectors. Expansion joints are divided into steel expansion joints, plastic expansion joints, and stainless steel plate expansion joints according to the material. Expansion joints can radially expand and contract within a certain range, and can also eliminate the displacement caused by different radial directions of pipeline connections within a certain angle, facilitating the installation and disassembly of valve pipelines. They can freely expand and contract within the allowable expansion and contraction range of the pipeline. Once the expansion and contraction exceeds the limit, they have a positioning function to ensure the safe operation of the pipeline. The key is to ensure the safe operation of the pipeline. The main functions are: compensating and absorbing the radial, lateral, and angular thermal expansion of the pipeline; absorbing equipment vibration and reducing the impact of equipment vibration on the pipeline; absorbing the deformation of the pipeline caused by earthquakes and collapses.
Both expansion joints and angle compensators have the function of compensating for offset, and their functions are similar. What is the actual difference between the two?
Expansion joint: large expansion and contraction capacity, high temperature resistance, and strong bearing capacity. During equipment resonance, geological changes, and changes in pipeline materials, the pipeline gradually bears stress, deformation, and distortion, damaging the pipeline, and even causing embedded pipelines to crack, causing great trouble for construction enterprises. To overcome these difficulties and ensure the safe operation of the pipeline, expansion joints and expansion connectors are used: they can radially expand and contract within a certain range, eliminating various angular movements, different centers, expansion, and swelling of the pipeline. The pipeline can freely expand and contract in the expansion joint. Once it exceeds a certain expansion and contraction amount, it has a self-positioning function, fully ensuring the safe operation of the pipeline.
