How to enter the values for the SW6 expansion joint, as well as the metal wall temperature?

Calculate the strength in SW6 based on the design conditions shown in the diagram, with a particular focus on determining whether expansion joints are needed
The expansion joints are entered according to the standard parameters of the GB16749-1997 standard for wave-shaped expansion joints in pressure vessels. It is recommended not to enter the expansion joint at this time; run the SW6 program to calculate the axial force and total axial displacement, and then enter the expansion joint parameters according to Standard 1 before performing further calculations ； Its purpose in calculation is to determine the stiffness of the expansion joint and to verify its strength. If the expansion joint stiffness and wave height are known, these parameters can also be directly entered at the tube sheet interface for overall calculation.
