Pickling and passivation of 304 stainless steel drums
Pickling and passivation of 304 stainless steel drums
(OP)
Dear all,
I am asking vendors to bid on several 304 SS drums with pickling and passivation. I got one bidder refuse to provide pickling and passivation with the following reason.
Quote "Pickling and passivating is done on A-403 stainless fittings. It is not done on Sect.VIII pressure vessels. We would be happy to work with you toward satisfying your metallurgical concerns on certain internal surfaces. Let's begin a dialog and discuss your concerns.” Further, if you know of service companies that can pickle and passivate whole vessels as large as 144”ID x 36’ T/T, we would like to be aware of them, so please share their identities with us." Unquote.
Is it correct from the above statement there is no need to pickle and passivate ?
(I have other bidder who has no problem of doing so by sub-contracting the work out)

Then the entire unit is passivated, often using a spray system and recirculating the acid.
I have worked with a couple of the guys mentioned above. They know how to do it.
