Hi gang,

Any suggestions on how to put this darn WC nozzle into a custom flange so it will not budge and may be removed down the line for replacement?

I'm sort of out of my league here; I need to figure out a way to secure a tungsten carbide flow jet (effectively a nozzle or plug) into a steel flange separating 2 pipes.

Its to be living in a sort of refinery situation, where there will be 300 degree heat, bidirectional flow, moderate pressure, and abrasive particulate in oil, oh my!

Being a machinist I thought, "shrinkfit and I'm done", but then remembered that at 300c degrees the steel flange is going to expand and loosen up and the Tungsten carbide (WC) is going to expand far less. Plus, this needs to stay solid for a looooong time, hopefully.

I'm thinking of having a shoulder on one side of the flange and some kind of pin/mechanical situation on the other side, or even brazing.

I'd really appreciate some help. I'm young and trying to shorten my learning curve.

Thanks in advance all.

Can you post us a reasonably detailed sketch of what you have in mind now ?
