Thank you for your input. We have had other tanks that have electric heaters in them but were at lower pressure. these tanks had been U stamped. Can you tell me what is the limitation for falling under section IV. Is it the Nameplate pressure, the heat input, the volume?
We have a U stamp and we were given a project with a 6000 gallon horizontal demin water tank that is to have a design pressure of 300 psig and it will have a 275 KW heater installed to raise the temperature to below saturation temperature. The hot water will be continuously pumped out at a low...
cockroach,
I am unsure what material you were using when you said that 1 1/2" sch 160 was sufficient. Was it A20 at 23,300 psi or 316 SS at 20,000 psi allowable stress? The equation I have to sue in this case is the one from B31.3 which is t=PD/2(SE-(P-y))
t= min thickness; P= operating...
We are working in high pressures in the 11,000 psi range. I want to use 1 1/2" piping. The allowable stress of A312 316 SS is 20K. The allowable stress of A20 pipe (No8020)is 23.3K which is just enough so that when I calculate the wall thickness required, I am Ok with 1 1/2" XXS pipe. My problem...
