I understand there’s limitations on threaded joints in B31.1. Makes sense. When doing pressure testing (hydrotest) beyond the pressure limit of said piping size, what’s the method for connecting temporary hydro testing equipment? We have used a hammer union welded into the piping system, but...
So, I'm in the midst of evaluating / modifying our CBD tanks, which were really never evaluated when they switched from AVT(R) to AVT(O). In searching for a maximum nozzle velocity, what I've come to notice is that "Blowdown tanks" CBD or IBD, and any design resources/guides seem to show them...
I'm evaluating one of our flash tanks which has experienced concentrated erosion directly downstream of the tangential inlet nozzle.
I've seen this posting regarding a similar topic:
