    Reinforcing Pad vs Gussets

    Thanks everyone for the responses, I've learned even more than I asked for with this thread. From what I understand gussets should not be used to reinforce the nozzle for internal pressures, only for supporting external loads on the flange/nozzle. Even then there should be great care to make...

    Reinforcing Pad vs Gussets

    Hi all, the COMPRESS software we use for validating ASME Code designs does not support gussets. This becomes a problem with higher temperatures and pressures, as the nozzles are usually the limiting factor. Forming metal into a "dome" to fit the ends of elliptical heads to use as repad is much...

    FFSO Flange Clarifications

    @GD2 More often than not just CS SA516. If the customer requests stainless steel then we go with 304 or 316. I just don't understand why we wouldn't offer the same connection as the customer has/is requesting.

    Understanding the Maximum Allowable Pressure

    From my understanding, the Maximum Allowable Pressure cannot be exceeded without some sort of yielding of the materials. 1. Is this interpretation of the MAP true? 2. Can the hydrotest pressure exceed the calculated MAP? If it can, what is the actual highest pressure it could be tested at? If...

    Basepad Support Failure

    Hi all, I'm hoping someone can explain what seems like a simple mechanical failure question, but one that has kept me curious for awhile. I have a pic attached showing an adjustable carbon steel basepad, capable of holding 800+ lbs. My question is, if additional weight was added until...

    UNEF Threading Above 1-11/16"?

    Hi all, We are having quality problems regarding 2" OD male threading. We get a "pass" result with our no-go gauge (not even a full turn on), but the customer is getting a "fail" when using their gauge. However, they specifically stated their gauge is from "G4988 2-16UNEF-2A Thread Plug set"...
