What to do to avoid the error in the floating head design
235 Floating Head (split ring): allowable stress at temperature missing (240 Deg C)
236 Floating Head (split ring): ambient allowable stress missing
237 Floating Head (split ring): exceptional ambient allowable stress missing
How to avoid it?
One possible reason for this error message to appear, the input data are not consistent. Meaning, the user was trying to model a BXT but AutoPIPE Vessel model was set to a BXS heat exchanger design.
S type means that the floating head is removable, this is not the case here, Shell Flanges-Rear Head End are missing! A Split Ring is required when the floating head is removable, otherwise this a type T.
To fix this issue, the user could insert 2 flanges in the shell or change the type of heat exchanger into BXT (there is no need Split Ring with a type T).
