I'm Designing a small vertical vessel (324mm I.D. and 1150mm T.T.) and i'm having trouble with a 3 legs configuration due to the orientation of nozzles. Can i use a two legs configuration?
That's why i ask, i can use two Lugs, but not two Legs... I know it have been donde before in small vessels (two legs and bigger baseplates with at least two bolts each). But calculations programs like Compress or Advanced Pressure Vessel doesn't allow this configuration.
It´s correct if i calculate the stresses in shell as support lugs, and then the two legs as supporting structures? the repad will be the same dimensions.
You didn't say where you are located but here is vessel design software that you can rent by the hour that has the capability of designing a 2 lug support.
Look at design features and then down to lug supports.
thanks unclesyd, but the design software i use, already has the capability to design and calculate the support as 2 lugs. My question was if i could use two LEGS, anyway i already resolved the issue using four smaller legs that does not interfere with the nozzle.
I came to this Forum to ask this question, thats what forums are made for.
I needed to make a quick decision, client did not approved the two legs design, two lugs where not allowed, three legs couldn't be because of the interferences, so four small legs was the option.
