On the issue of corrosion margin for stainless steel storage tanks
Thread Content
Hello everyone, I have a question regarding pressure vessel design and would like to consult you: For compressed air storage tanks, can the corrosion allowance be set to 0? The tank is made of 304 material, with a design pressure of 1.6 MPa.
Carbon steel is sufficient for compressed air storage tanks; a thickness of 2 mm is adequate for a design life of generally twenty years. If it’s stainless steel, there’s no need to remove it
Thank you. The client requires 304 material; for carbon steel we apply a corrosion margin of 1.5 mm, while I’m not quite sure about the requirement for stainless steel
Refer to the GB150 corrosion design manual
Using 304 is a bit of a waste; it’s completely fine to use 0 instead
The property owner can be selfish because they have money! The corrosion allowance is 0
Is stainless steel used for compressed air storage tanks? \ud83d\ude22 Is that expensive?
