Regard to Process Static Equipments, when it is necessary to carry out Pickling and passivation. If we don’t do pickling and passivation, how it is going to effect the product when put in service?
Sometime, only pickling and passivation is carried out only for weld portion, why it is so? Also sometime only pickling is carried out.
Request to for guidance on above.
Thank you,
