Problem:

Under what circumstances should ""Consider Bolt Spacing Correction" option be enabled on the Analysis Tab of AutoPIPE's flange Analysis module?

Solution:

This is an engineering judgement call that you must decide. Read AutoPIPE help "ASME Section VIII, Bolt Spacing Correction Factor" for details about this feature. 

Question: in reading help section there is a reference to "Leathel Service", that may not be perfectly clear. Does this refer to military vessels or to aeronautics?

Answer: AutoPIPE help information was created based on information from a particular codes. Refer to the indicated code for definitions and terminology. In this case there are Two definitions of lethal service provided in ASME VIII Div 1, section UW-2. 

For legal reasons, Bentley does not provide code interpretations, the user must determine if a service is lethal. Suggest to submit a question to the code committee for interpretations about the code.
