low pressure (50 psi) rupture disk
low pressure (50 psi) rupture disk
(OP)
We're designing in a pressure relief with a set point at 50 psig and I was looking at using a rupture disk as an alternative to a spring seated design. The device will have to be small (<.875" OD) so finding an off the shelf has been difficult

Just be sure to select one that is suitable or certified for use on the equipment you are trying to protect.

Putting a special rupture disc on a 3/4" nozzle, buying spare discs, etc., will probably wind up being more expensive than buying a small safety-relief valve. Also TD2K brings up an interesting point about fatigue: a tension-type rupture disc typically has an operating to burst ratio of 70 percent. If you go over 70% of burst in service it probably won't burst the first time, but the next time you exceed 70% it will probably blow. A SRV or a buckling pin will not experience that AND a SRV will reseat so there is less mopping to do after the event.
