Venturi welded ring
Venturi welded ring
(OP)
I have a venturi that is being used on a feedwater system. There is a welded ring at the outlet (see picture, circled). What purpose does this ring serve (contain vibration, thermal, or just to support outlet cone)?





RE: Venturi welded ring
Without that weld, the venturi would be a high-speed bell, clanging back & forth in your nozz. Plus, things should be supported from both ends and not cantilevered when possible.
RE: Venturi welded ring
but I have to say that they venturis were in single piece meter tubes for HP steam.
