Fin fan cooler/Air cooled Heat exchanger Header box Hexagonal threaded plug design calculation-Reg.
(OP)
Hi guys,
I am working on the design analysis calculation for a Fin fan cooler/Air cooled heat exchanger as per ASME SEC VIII DIV-1.
In plug type header box Hexgonal threaded plug design can be done as per ASME SEC VIII DIV-1 Table UG-43 as shown below
DESCRIPTION UNITS Header Box Plug
Plug Size INCH 1-1/8"
Thread Type - UNF
No of thread per inch - 12
Minimum Plate thickness required As per Table UG-43 mm 15
Used Plug sheet thickness mm 25
Minimum Threads engaged As per Table UG-43 - 7
Total No of threads engaged - 11.8
MOC - SA 105
or any other Acceptable design calculation is available?
Please advise.

Thank you for the reply i had completed the design analysis calculation as per Appendix 13 of ASME VIII-1.
but this Table UG-43 for pipe threads or is this applicable for Hex plugs also?

Is API 661 Standard provides how to justify for Hex. Plug or design of thread strength calculation?

API 661 is clear and easy to understand. Please read it slowly, and again.
Table UG-43 is not applicable.
