How many cycles can a rupture disc achieve before failing?
HPX® rupture disc tested to over FIVE MILLION cycles. This cycle test is more than 5x greater than previously achieved in the industry.
The 1″ 22 psig-rated disc was subjected to 5,050,000 pressure/vacuum cycles without failure. After completion of the test the HPX disc passed all non-destructive testing to confirm the disc integrity.
The rupture disc was then burst-tested and had an opening pressure within the design tolerance.
