Things to check:
Have a pickling tank with approx. 10% phosphoric acid at 130 degrees F with a serpentine gas-fired side-mounted burner tube in the bottom. Tank construction is entirely 304 stainless. Having a problem with burner tube leaking, always at a welded location. DESIGN GUIDELINES FOR THE SELECTION AND USE Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are:1. Metallurgical Structure. 2. The AISI numbering system:namely 200,
When the oxide scale is heavy and tenacious the stainless steel may be treated for 5 to 10 minutes in a bath of 8 to 10 percent sulfuric acid at a temperature of 150 to 160°F (65 to 71°C). Upon removal from the bath, the part should be scrubbed to remove the sludge and after rinsing, pickling can be finished in a nitric-hydrofluoric acid Finishing Chemicals Böhler WeldingWe help you restore stainless steel. Stainless steel retains its beautiful finish thanks to a protective layer that forms on the surface. Our products help customers around the word in their daily work of creating a superior stainless steel surface. Pickling of stainless steel is the technically superior method to obtain the best corrosion
After pickling, the surface color of stainless steel is white and bright. The color of chromium-nickel stainless steel is white and like a jade; The color of chrome stainless steel is white and a bit gray, it also have a weak luster; The color of chromium-manganese-nitrogen stainless steel is similar to that of chromium-nickel stainless steel, but it is lighter.

Pickling carbon steel pipe is a very caustic process. A pickling reservoir is essentially a pure acid bath that will strip everything off the steel. Also, any foreign matter, rust, grease, oil, everything.
Pickling steel is the process of applying an acid solution to remove heat affected zones along with the underlying chromium reduced layer from the stainless steel. Pickled steel is free from surface carbon steel contamination and embedded iron particles.

Mixtures of nitric and hydrofluoric acids are usually used for pickling stainless steels. Pickling is the process used to remove weld
Pickling is the removal of any high temperature scale and any adjacent low chromium layer of metal from the surface of stainless steel by chemical means. Where the steel has been heated by welding, heat treatments or other means, to the point where a coloured oxide layer can be seen, there is a chromium depleted layer on the surface of the Pickling and Passivation of Steel Pipes - www Some stainless steel pickling or pickling by adding hydrochloric acid, perchloric acid, ferric chloride and sodium chloride and other chloride-containing corrosive media as the main agent or additives to remove the surface oxide layer, with the exception of grease trichlorethylene such as chlorine-containing organic solvents, from the prevention of stress corrosion cracking is not appropriate.
Why pickling and passivating. During the installation of the stainless steel pipes in a system and / or installation, the surface is exposed to many mechanical and thermal treatments. This causes damage to and contamination of the protective oxide skin. This results in the loss of corrosion-resistant properties.
