Is there a way to invoke Code Case 2901-1 in Compress?

Appendix 2, Figure 2-4, Note 4 reads in part, "Facing thickness greater than 1/16" shall be in excess of the required minimum flange thickness, t; those equal to or less than 1/16" may be included in the overall flange thickness." I interpret that (rightly or wrongly) as I may consider 1/16" of...

Anybody know the 'mandatory' date for Section VIII 2013 Edition?

Colleagues; Is there a maximum thickness a vessel head/shell can be under the rules of ASME Section VIII, Div.1? If so, is it further limited by material selection (ie; P1 may be thicker than P8)? I don't know why, but I am under the impression that 8" is the maximum permitted for butt...

I have a tangential nozzle set high in a horizontal vessel such that the long axis of the opening is greater than 2x the short axis. UG-36(a)(1) indicates when this is the case, reinforcement across the short axis is to be increased as necessary to protect against distortion. Anyone know how I...

Is there a way using Compress to model/calculate a 'branch' connection? What I have is a 20" liquid outlet out of the bottom head. In the horizontal part of the nozzle after it exits the skirt, there is a smaller 4" branch drain nozzle attached. Any ideas??

Sorry to anyone who read this already, I also posted in the Vessel forum. Is there any merit in normalizing SA-106-B? I'm on a job now where the request is as per above for use on vessels subject to sulfide stress cracking. I've heard people say that SA-106-B has no merit to normalizing as it...

Is there any merit in normalizing SA-106-B? I'm on a job now where the request is as per above for use on vessels subject to sulfide stress cracking. I've heard people say that SA-106-B has no merit to normalizing as it will not move it from curve B material to curve C material as per UCS-56...

Can anyone explain the meaning behind between UG-99(c)? When would you use this paragraph instead of UG-99(b)?

Reference Appendix 1-4(c), the formula has a value "k" which is taken from Table 1-4.1. Note post script note 1 which starts "Ellipsoidal heads designed under K > 1 ..." Also refer to Example 1. There, the ID is indicated to be 40, and value h is indicated to be 9. If this is a 2:1 head with...

I'm getting the following deficience error on my top head of a vertical tower: * External design pressure varies across this chamber. Any thoughts as to why?

Does anyone know how to design a nozzle through/on an ANSI blind flange in COMPRESS?

I've been hearing the term "high alloy" a lot lately, but nobody seems to be naming any specific grades of steel. I'm a little confused by the term, not sure what kind of steel they are talking about. Is it chromoly and high nickel steels?? Can anyone list for me common grades of "high alloy"...

I have a vertical carbon steel vessel, 7/8" thick. Bottom portion is internally integrally clad with 317 SS. I interpret UCL-34(b) as all clad vessels are to be PWHT unless clad with 405 or 410S. Can anyone offer any rationale as to why I may be able to "not" stress relieve this vessel? My...

Hi all. This is my first post, so go easy on me if I violate any forum protocols. I have a simple Section VIII Div.1 pressure vessel that will operate in cyclic service. I would like to perform a Fatigue Analysis as per the rules of Div.2, AD-160 Fatigue Evaluation, Appendix 4 Stress...
