@DekDee I thought an engineering message board was a place where we could ask questions and get advice from other engineers, but apparently "trying to find out if something is acceptable over an internet forum is not a good idea". I was never going to make a decision based on what someone told...
@MJCronin,
ASME B31.3 Chapter IX, this is a duplex stainless steel API 10,000 piping system. You are correct it will be operating at a high pressure (normally 3-4,000 psig) and tested at a high pressure (15,000 psig since it is a 10,000 psig design pressure).
The system does have some 12" NPS...
@Duew6 - Thank you for your advice, where are you getting this requirement from ("...requires a 1/4" fillet weld..."), so that I can see it for myself and educate myself?
Thanks,

@Duwe6 - It is a 1" diameter hole. The threading (NPT) is 3/4" long, the rest of the hole (unthreaded) is 4-5/16" long.
@BigInch - The hole in it is already threaded as described above, it was used to hydrotest 5,000 psi for a different application.
@LittleInch - Yes I am aware that this is a...
We have a 12" SPO blind flange (duplex SS) with a small hole in it that was used for a hydrotesting connection. We need to determine if it will be acceptable for a 15,000 psi hydrotest with a plug in that threaded hole (3/4" threaded, the rest of the hole is 4-5/16" w/o threads). The thickness...
