With regards to welded piping attachments (structural shapes specifically, plate, etc), I have a project were MDMT = -20 deg F. Per my reading of B31.3, A36 and A992 materials Min Temp per Table A-1 puts you into Curve A of Fig. 323.2.2A and this states a design minimum temperature of ~+15 deg...
[b]Thank you for the responses fellas. Interestingly, I've gotten Paulin (NozzlePRO) involved and they don't actually have a good answer for me as of yet. I'd understood that they don't see anything technically incorrect with this approach, however it's more of a code/legal issue as Section 1...
I'm working on a project where the vendor of an existing HRSG (BPVC Section 1) will not provide stated nozzle allowables for their steam drum connections. Instead they've provided the nozzle fabrication details (nozzle/shell materials, thickneses, repads, etc) for us to perform our own...
Thank you for the reply, much appreciated to get some insight on this.
To clarify the 'P' value portion of your response, let me propose at quick hypothetical.... say i have a PSV set at 200 psig set pressure and a 6" sch 40 outlet. Per the rules of API 520, the approach to determine the...
I'm calculating the safety valve reaction forces using the equations out of B31.1 Nonmandatory Appendix II (for a steam PSV) and out of API 520 Part 2 (for a flare gas PSV). I have a few questions regarding these calcluations:
1. My understanding is that B31.1 Nonmandatory Appendix II is for...
I'm looking for information on dynamic analysis requirements for flare system header piping, looking at this from a pipe stress standpoint.
I'm looking at a flare line header pipe DOWNSTREAM of the main knockout drum, so my assumption is that I'm only looking at gas flow in this specific...
Does Section IV code restrict working fluids to WATER ONLY? Are there exceptions in the code to allow for any amount of a Glycol/Water mixture in a Section IV boiler?
I'm scouring the Section IV code myself at the moment, but just thought I'd see if anyone could help me out.
