Flexibility of Bellows and Lens Expansion Joints

Elastic properties of bellows and lens expansion joints are their linear and angular flexibility. These properties must be input for all pipelines with these types of expansion joints. Although these data are often provided in expansion joint catalogues, they are hard to utilize due to complications with terminology. To simplify this problem, elastic properties are determined based on structural parameters that are easy to understand.

Input data can be copied using the toolbar icon and  inserted into any other Start-Elements analysis by using the toolbar icon in that file.
