Dears,
I encountered an advisory warning when designing Atmosheric flash tank with design temp = 510°C stating:
"The temperature of 510°C is above the CS-2 vacuum chart temperature limit of 480°C."
It appears that while the software calculates the allowable compressive stress using CS-2...
Hello everyone,
I am struggling with designing a multi-chamber vessel using COMPRESS. I've attempted multiple approaches but have not been successful. I also tried incorporating an intermediate skirt to connect the chambers, but that didn't work as expected either.
Has anyone here successfully...
I have concerns regarding the estimation of nozzle and flange thickness under hydrotest conditions. A 30" flange with a Sch. 10S (7.92 mm) wall thickness was flagged because the nozzle assembly failed under hydrostatic test stresses. To mitigate this issue, I increased the nozzle neck thickness...
when I add the option to check saddle plate stress, Base plate thickness increases a lot. can anyone explain the effect of checking saddle plate stress and whether it is mandatory or optional?
A closed drain drum having a 2" nozzle with blind flange RF.
Should I use the UG-34 calculations and include the corrosion allowance of the vessel to the flange thickness? or use the typical standard blind flange with a suitable rating without considering corrosion allowance?
we already...
In compress,
After choosing class 150 , compress send the message attached , IMPACT TEST IS MANDATORY AS PER UHA (d)3. but when I change the class to 300 impact test is not required.
I have the same message when I add external loads and increase nozzle projection.
Can Anyone explain why?

How can you differentiate between an Sour Service with Lethal Service?
All Lethal Service requires PWHT and 100% RT for butt welds for Pressure Parts.
Do all Sour Service are Lethal in Nature? If not what is the requirements of sour services(non lethal) according to ASME VIII-Div1.
In compress,
Using slip on flange in 2" pipe sch.160 will lead to a deficiency in external fillet weld.
" UW-21: External fillet leg minimum (9.02 mm) is greater than the flange hub thickness (7.87 mm) " this message is shown during code calculation. but in UW-21 external fillet " X min = the...
Since compress does not allow attaching any nozzles (center or off center) to ASME B16.5 blind flange.
Can I do the calculation with UG-34 cover to easily attach nozzles and in drawings replace it with Standard blind flange?
I am designing a pressure vessel using compress software .the PV is 24" OD and has a bolted cover.
we want to use standard slip on flange & blind flange but we need to make an opening in the blind and we can't do it in compress.
1) can we use a UG-34 cover with the same dimensions of standard...
