Several data that are particularly important in the customization of the bellow compensator

The corrugated compensator is a compensating device that uses the effective expansion and contraction of the elastic element of the corrugated compensator to absorb the dimensional changes of pipelines, conduits or containers caused by thermal expansion and cold contraction.

1. Pipes with large deformation and limited spatial position.

2. Large diameter pipes with large deformation and displacement and low working pressure.

3. Equipment that needs to be restricted from taking over the load.

4. Pipes required to absorb or isolate high frequency mechanical vibrations.

5. Pipes required to absorb earthquakes or foundation settlements.

        This link is the most important, strictly refer to the national standard to decide, and cannot determine the number of bellows layers according to the way of thinking without test data. Determine the number of layers of the bellows according to the use of the bellows, working pressure, stiffness, working medium and other factors. It is known from the analysis of different calculation formulas that under the condition of equal total wall thickness, the stiffness of multi-layer bellows is only 1/Z or 1/Z of the stiffness of single-layer bellows. Therefore, the multi-layer corrugated pipe has many advantages such as low deformation stress and long service life. In the case of high working pressure, the multi-layer corrugated pipe is generally selected. For dry multi-layer corrugated pipes, the number of layers and the single thickness of the single layer should be reasonably selected.
