Hi all,
I am reoriginating an electronic calc for blanks as per B31.3 para 304.5.3. Something that has struck me regarding the calc that I have to work with is that the original author made an allowance for 2x the groove depth on RTJ flanges. Obviously this is giving a pretty large safety margin, (additional 11mm in a 1/2" system), however is this the norm or is it too much? I can see no reference to this allowance anywhere else.
Thanks !
Kevin
