Branch outlets using threadolets

Hello,

I need some guidance regarding a oilfield piping design where I looking at using 2 threadolets on a 5" 5000 psi working pressure piping run with the first threadolet at 5 3/8" from the end of the pipe which is welded to a mud gate valve end connection and the second threadolet at 12" away from the first threadolet and on the same side as the first. The piping components are all for H2S service and will be used in an environment where the temperature will range from -50 deg. C to +40 deg. C. The ASME B31.3 code is somewhat unclear on whether this type of configuration is allowed. It does say that threadolets (as per Table K326.1) are OK but not exactly whether having them side by side is OK.

Can someone address this topic, please?
