Max Action Posted April 27, 2010 Share Posted April 27, 2010 I'm still researching systems, and have seen a number that incorporate both copper and stainless steel components. Does anyone have any problems with corrosion where these dissimilar metals meet? Link to comment Share on other sites More sharing options...
Maggie C Posted April 27, 2010 Share Posted April 27, 2010 As far as I understand those are classic materials. Stainless typically in condensers and copper in the body of the still, etc. Link to comment Share on other sites More sharing options...
Spirit of Texas Brad Posted April 27, 2010 Share Posted April 27, 2010 I'm still researching systems, and have seen a number that incorporate both copper and stainless steel components. Does anyone have any problems with corrosion where these dissimilar metals meet? It depends on the level of heat utilized when joining the metals. You can change the chromium levels in the immediate vicinity of a weld and stainless will corrode. There are non-heated flange approaches that will never have a problem. A good welder with the appropriate thickness materials can make it happen. I've got copper welded on stainless now and will not let wash set in the joints between processing runs. I just want to make sure corrosion can't get a foot hold. Cleanliness is next to ... Cheers! Brad Haden Spirit of Texas Link to comment Share on other sites More sharing options...
