Mating SS Flange to CS Flange
Mating SS Flange to CS Flange
(OP)
Does anyone has any experience and/or advice with regard to corrosion aspect of mating stainless steel pipe flange to carbon steel flange? Will there be any galvanic corrosion? What materails to be used for bolts and nuts?

One problem we and others have run into is with CS/SS flanges in Class 150 especially in the 3" and 8" sizes.
We got into a big trap on several large projects where they used CS backup flanges for SS lines mating with SS flanges.
Just because it works on paper doesn't mean it works in the field, check around and see if your people have any experience in using the combination in certain areas as atmospherics are not the only problem as process can enter the picture.
