MAWP Listed in COMPRESS Table
MAWP Listed in COMPRESS Table
(OP)
I am reviewing a vertical vessel that I recently designed with leg supports. The legs are wide flange beams. There is a MAWP listed in the pressure table, for the legs. I have reviewed the leg support calculations, and they do not use the MAWP or design pressure. I am a little confused as to why the vessel MAWP would be listed for the support legs, when they are not a pressure containing part. I am using the latest version of COMPRESS. Thanks for your help

Thanks for the response. I think I see where you are going, but do not see how the MAWP would come into play if we are not dealing with any pressure containing components. The attachment to the shell should be a weld strength calculation. This is what I am thinking. Thanks.....

The stresses in the shell are based off the design temperature, correct? I am thinking that the material stress of the shell material, that would be used to check the loads form the lags against, is based off the design temperature and not the MAWP. I went back through all the calcs and did not see anything with pressure. Thanks...

Welcome to Eng-Tips!
Though you are getting good responses from two well known contributors in this thread, next time I'd suggest you post to either:
forum1259: Codeware: COMPRESS
or
forum794: Boiler and Pressure Vessel engineering
You'll get a more focused audience at those forums as opposed to this "other topics" area.
