I suppose you do sweep blasting before Painting and there is no purpose for Pickling and Passivation.

Dear Experts

Do we need pickling and passivation of SS surfaces before painting them? Could you please suggest any specification relevant this requirement?

The parts are SS cast valves requiring painting.
