John,
The point of the discussion was that ASME Section VIII Div 1 Appendix 24 details a calculation method which no manufacture is able to meet. This difficulty is explained by Chris in the previous posts. Considering that the calcs are so difficult to solve. ASME should either provide a simplified procedure or standardize the product. Therefore my suggestion.
Why would a product want to remain proprietary. Would it not have more standing, if it has the blessing of the code. Moreover, since it is known that the flanged joint is not the best of joint types. Why wouldn't ASME not invest it's time on evolving a better joint component that can used on new projects? I would like to know your thoughts on this.

Your Question:
Why does not ASME standardize the Hub joints. Since the manufacturers are
currently not code compliant. This would allow to have code compliant hub
joints available.
I speculate that the ASME does not want to involve itself in the development of a propieatary design standard. You have flanged, screwed, and welded joints where do you stop???? Besides which theres plenty to do with what joints we already have... (research and development of new additions to what code rules already exist).
