Hi Derek - thanks for the response and the link. I have read right through but could not find anything that said don't use brass for an oil separator I have mentioned this before somewhere but several years ago - before I had even heard of de-zincification I made a home designed, sort of yarrow type, boiler using some brass tube scrounged off the chief engineer on the Glomar North Sea (drill ship). I used some brass sheet of unknown quality for the end plates which I formed in a small press tool in one hit without annealing (gives an idea of it's malleability). Within a year I added another off take and re-pressure tested it but could not raise the pressure beyond a few pounds as those end plates were totally porous Since then I have always been suspicious of using brass in any steam application.Your suggestion of soft solder sounds feasible - the heat should not be of concern by the time it arrives in the vessel and besides I do have some high temp SS.Thanks for your input as usualRegards - Ramon
