When calculating the expansion joint for SW6, how should the axial displacement required of the expansion joint be determined?
In the “Input of expansion joint calculation parameters” section, the user is required to enter the total axial force or total displacement of the expansion joint before calculations can be carried out. If the tube sheet calculation has been performed prior to calculating the expansion joint, then there will be a default value for the total axial force of the expansion joint, which is derived from the tube sheet calculation. It is recommended that users use this value for the calculation of the expansion joint.
It should be the difference in thermal expansion deformation between the tube side and shell side in the tube sheet calculations, multiplied by the length of the heat exchange tubes
