At what pressure would you recommend using RTJ over RF?

RE: C02 flood

Explain your acronyms!

RE: C02 flood

Most people shy away from RF on ANSI 900 and above flanges.  

RE: C02 flood

@ anything equal or above 1000 psi

RE: C02 flood

I don't have a problem with RF on ANSI 600 (typical MAWP 1,440 psig).  ANSI 900 pressures call for RTJ.

RE: C02 flood

Same for me - I use RTJ on 900# and above unless the piping is inside a building and I might need to get it apart.  Then I revert back to RF for easier disassembly.  Use a torquing crew and leak check or IR if in sour service.
