Corrosion Allowance for Nozzles
Corrosion Allowance for Nozzles
(OP)
Hi,
Good day,
If user specify corrosion allowance 1 mm for shell, toricone and 0 for top dish end. Its a vertical silo.
Now my question is what would be the corrosion allowance for the nozzles on shell, toricone and top dish end?
Does manufacturer of pressure vessel can use 0 for all nozzles?
Is there any rule applicable as per ASME VIII Div. 1?
Thank you.

You would use, for nozzles, the same CA as for the part in which they are located, unless the material for nozzle is different (e.g. SS instead of CS).
