SW-6 calculation for fixed-tube-sheet heat exchangers
Thread Content
SW-6 is used to calculate fixed-tube-sheet heat exchangers; no calculation results are generated, and the circumferential welds of the shell cylinder are set to zero. Please check the input data. Help, what’s the problem here? Thank you.
Was the circumferential weld coefficient of 0.6 for the shell side cylinder not entered?
Was the circumferential weld coefficient of 0.6 for the shell side cylinder not entered?
Has the circumferential joint coefficient been entered here?
The circumferential weld coefficient here is specifically applicable to butt welding; so how should the fillet joints between the tube sheet and the shell be considered?
As I understand it, the purpose of introducing the ring seam coefficient here is to verify the axial stress in the shell side cylinders; therefore, it applies to circumferential joints. If the cylinder and the tube sheet are joined using corner joints, there is no need to consider this factor.
