Pickling and Passivation

Our Team is experienced in Pickling and passivation Stainless steel, Duplex, super Duplex and Titanium materials. Pickling is the removal of thin layer of metal from the surface of the stainless steel and to remove weld heat tinted layers from the surface of stainless steel fabrications, where the steel’s surface chromium level has been reduced.
Passivation usually occurs naturally on the surfaces of stainless steels, but it may sometimes be necessary to assist the process with oxidizing acid treatments. Unlike pickling, no metals is removed from the surface during acid assisted passivation.

Pickling Methods:

  • Tank immersion pickling ( Bath size 10000 mm Long x 3000 mm Wide x 1000 mm Height)
  • Spray, brush pickling pastes or gels.
  • Circulation pickling. (It is recommended for closed tanks and pipe work, which required internal cleaning.
