I think that I have explain incorrectly. Im not asking how much should be de CA value, always I take 3mm for this type of equipment (maybe you have understand this?).
Say in another way:
The formulas in the ASME (commonly) are without CA and, after you calculate the value of t you add the CA...
Thank you very much Mike! I will use the CA coeficients as you say, although I think is not so logical ;D
Ummm... How you know that you have to take the CA of the vessel instead of the CA of the nozzle? In the ASME only is talk about the thicness calculation without the CA.
I know you are...
One more question...
I have take a corrosion allowance of 3 mm for shell / heads and 1.5 mm for the nozzles (as is said in the Heat Exchange Institute Standard for Deaerators).
In the calculation of the values of UG-16(b), UG-45(b)(1) and UG-45(b)(2), which value of CA shall be use, 3 or 1.5...
Hello everybody!
I'm calculating a nozzle neck thickness per UG-45 and I'm not sure about which is the minimum thickness specified by UG-16(b).
My equipment works with steam / water and the material is in the Table UCS-23, then for shell and heads the minimum thickness is 2.4 mm per...
