Dear All,
Can you help!!
habitually we fabricate Clamp Ferrule using Rod Bar SA-479-316 for 4" dia. and less, UG-14(b)does not accept this material for 6" dia.I think to use piping material: SA-312-TP316 , So I can machine 6" pipe Sch80 to obtain 6" ferrule.IS IT CORRECT TO USE THIS MATERIAL...

Hi,
I have to design a storage tank containnig LIQUID CO2,
to ASME sect VIII div.1 ,MAWP 350psi, MDMT -40 deg.F, 8'dia., 26'H.Matl'S: SA-612,
I started to get physical properties of CO2,in order to determine the optimum operating (Temp., pressure).and reading some technical documents related to...
Hi,
it depends in witch step are you performing,
if you have to design pressure vessel to negative pressure, it means : external pressure , so you have internal (+) and external(-),
generaly we say designing to full vaccum it means: External pressure of 14.5 psi,
in this case you consider both...
Hi,
Thanks for all your confirmation and propositions, it was very interesting.particularly this from doct9960:
"I checked the Code and found out that you can place repads on the inside, but you need to meet the requirements of ASME VIII-1 UW-16(c)(2)"
I think also that the FEA analysis is the...
Hi,
did some one know this situation:
I have to recalculate the reinforcement required for a 24" Nozzle on Head taking in account a new loads ( caused by piping loads), the vessel is already in shop,
the first calculation ( without new loads)require a pad
( 4" x3/8")as reinforcement, this pad...
