API Flange/Linepipe selection/matching

Does anyone know of a rule of thumb type guide to selecting and matching standard commercial pipe sizes to API 6A 10k flanges (which have a range of bore/hub combinations and dimensional limits) 5K flanges can be quite straight forward as the API hub sizes match NB pipe, I always have to think twice when 10K flanges are involved as there are ususally two sizes that may be apropriate within the limits subject to the required bore parameters presented by the process engineers.

Many thanks
