    Orifice tap max loads?

    Thanks for the feedback mk3223- do you mind schooling me on what you mean by "bridge welded"? I am not familiar with this term.

    Orifice tap max loads?

    KevinNZ- thank you. That's where I started with this. I modeled them in caesar and applied a Socketweld SIF as these are welded taps, not threaded. Just was curious if there were any other obvious routes for analyzing.

    Orifice tap max loads?

    I’m curious if there’s any suggestions for coming up with maximum loads that can be applied to 1/2” nipples on the taps on an orifice flange pair?

    ASME VIII UG-44(b)

    Great! These Fm values are indeed substantial relief. My test model shows before vs after flange rating selection as a result:

    TGS4- do you have any more insight on when code case 2901 revision will be published?

    Pipe Stress - ASCE 7 section 15.7.4

    RVAmeche, I again am not in disagreement with you. I would be interested in knowing your thoughts for calculating displacements other than table 15.7-1, again from a point of substance and technical backing that would hold up in court of law. I think there's consensus that the requirements...

    Pipe Stress - ASCE 7 section 15.7.4

    1503-44, while I agree with much of what you say, that is not how the ASCE7 chapter 15 is written based on my understanding. And being that it is adopted as law, one could not justify feelings on the matter as an excuse to not perform very clear directions provided by code in court of law...

    Pipe Stress - ASCE 7 section 15.7.4

    This discussion is veering off topic a bit. It wasn't intended to discuss seismic accelerations on the piping itself. I think that is a standard analysis performed using different strategies. I use ASCE7 chapter 13 within Caesar for that analysis and that topic is very well understood in my...

    Pipe Stress - ASCE 7 section 15.7.4

    ASCE 7 is the code for "Minimum Design Loads and Associated Criteria for Buildings and Other Structures" adopted as law directly or indirectly via IBC in just about all states in the US. I've attached one of the applicable snapshots. It has specific direction for piping connected to vessels...

    Pipe Stress - ASCE 7 section 15.7.4

    I'm trying to get a feel for what those in the oil & gas/chemical/industrial industries are doing in terms of pipe stress performed on piping connected to pressure vessels and exchangers. If you read ASCE 7, it is clear to me that the intent that piping attachments to all these pieces of...

    ASME VIII UG-44(b)

    Thanks for that input. Do you mind making sure I understand this appropriately? Here's how I understanding it: Code case 2901 was the source of this topic originally, then it was moved into the mandatory section of the VIII-1 code. Now a revision to that original code case 2901 will be made...

    ASME VIII UG-44(b)

    I've seen rumors floating around for a few years that this section is being potentially revised/removed in future editions. Anyone have insight? In any case, I've followed this discussion for years and still haven't had much success resolving the intent, what to do with the "may" statement...
