      I am somewhat familiar with Rupture disc's
      we used them in Plastic extruders, only at 6,000 to 12,000 PSI.
      First of all, you are working with Nickel, one of the best corrosion proof
      metals around. I suspect that either you are not getting Nickel discs, or
      the disc's have a flux product residue. or you are getting spikes in the pressure line, or you are running too close to failure during operations
      So
      Can you confirm the base metal and is it an import?
      Have you washed the disc's before using them? or litmus test them
      I have seen salt spray tests on Nickel and it sure seems your experience
      is exceptional. If you want to protect the disk coat it with paraffin wax.
      What confirms that the pressure is OK, We had the problem with several customers, and it was the pressure gages that were off. (ie. the disc's worked)
      Lastly, does the failure occur at the same time of day ? or point of operation?
      ( customer had an operator close off the recording gauge , and increase pressure to get more outpoint )

      hope i have given you food for thought.

        What about PTFE pipe sealant? Or a thin wipe of silicone gasket glue?
        I just need one more tool,just one!

          Or polish them up with carnuba wax.
          I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-
