One of the valves on my 3 bar line just failed. Without it, our production has ground to a stop and we can't operate until we get a replacement (which we have already ordered). In order to make a deadline, I am trying to find a way to use a (properly rated for pressure) DN 16 flanged valve to fit with the existing DN 10 piping.

Is there any way to (safely) connect these two flanges together temporarily?

  • Can you find a flanged reducer? We use these all the time in our production plant. They especially are useful for changing the diameter of the line when installing fittings. – tralston Jan 21 '15 at 06:07
  • @tralston don't have a proper one on hand / can't get one faster than the proper valve. – jmac Jan 21 '15 at 06:58
  • @jmac if you cannot get a flanged reducer, are you able to connect your system via another pipe with different flanges on each side? – smiddy84 Jan 21 '15 at 08:12
  • Can you just Zeus it on with a weld? – Inthebay Jan 27 '15 at 08:06

If you have access to a lathe you should be able to quickly machine a flanged reducer out of Nylon 6. Not sure what temperature you're operating at but make it a bit thick and it will easily be able to handle 3 bar.
