    Copper seal with stainless steel pipe

    Hello. I designed methanol dozen station, MOC - 316SS. So I used copper seal in gauge (pressure gauge, for example) place connection (flat type seal) like always. So, customer checked station's draws and other documentation and said, that using copper seal is not acceptebale. Now I have a...
