I have to design a domestic water tank (15psi max)to fit inside a boiler water tank (30psi max), all stainless steel. Does anyone know if asme will consider the overall volume of the two tanks as one even though they are completely separated from each other and have their own prv's. I want to...
Is there a "rule of thumb" for non asme (under 120gal/450L) tanks holding domestic hot water or boiler water but operating within the excepted temp/pressure limits of our typical systems( ie: 150 lbs relief and 100C)
Thanks
