Hello all. I am looking at a vertical shell and tube heat exchanger built to ASME code Section VIII, Division 1 and stamped. The shell is 20" in diameter. The tubesheets are extended as a flange for bolt-up of the tubeside channels.
Each fixed tubesheet has a drain/vent drilled into it.
To...
Does anyone know if there are any specific reasons why API has added note 4 to paragraph 5.6.1.1 in the 11th Edition of API 650, June 2007? The note states that tanks with diameters less than 50' but greater than 10.5' require a minimum thickness of 0.25" for the lowest shell course, rather...
I am embarrased to ask this question that is likely extremely easy. But for a pump designated as 6x8-13, what do these numbers stand for? I am guessing the 6x8 are flange sizes, but what about the 13? Sorry for a question that I think I should know but have not found an answer and hope one of...
The company I work for builds many shell and tube heat exchangers to ASME Section VIII Div 1. Typically they are low pressure low temperature exchangers (15psi/250 deg F). Almost always, we use double groove expanded tube-to-tubesheet joints. The grooves in the tube hole are typically located...

I occasionally use the General Arrangement Drawing option within Compress. I notice the drawing does not show vacuum rings. Is this an option that can be checked? If not, possibly if enough people use the GA and would like to see vacuum rings, this option could be added in the future.
Thank...
