Different stainless steel pipes call for distinct surface treatments, such as
Pickled finish or sand blasting finish
Polished finish
Inside and outside polishing
Pre-treatments
Pre-treatments like pickling, chemical brightening, electrochemical polishing, electroplate, passivation, black coating, color coating, chemical machining, are important steps to do surface treatment on stainless steel pipes. Before stainless steel pipe taking shape, the surface is likely to have oils, burs, uneven surface and oxide, hence, these flaws should be removed before doing surface treatment.
