What is a Rupture Disc?

How do I choose a ruptured disc?
Select the upper limit of the manufacturing design range. This is typically the maximum allowable working pressure (MAWP) of the equipment being protected, but in some applications, may exceed the MAWP. When superimposed back pressure is present, more care must be taken in selecting the upper limit of the manufacturing design range.
2. Determine the specified burst pressure by subtracting the positive portion of the manufacturing design range from the upper limit of the manufacturing design range.
3. Determine the lower limit of the manufacturing design range by subtracting the negative portion of the manufacturing design range from the specified burst pressure.
4. Determine the operating ratio by dividing the maximum operating pressure by the lower limit of the manufacturing design range.
5. When calculating the operating ratio for rupture discs with burst pressures from 15 to 40 psig, subtract the required burst tolerance of +/- 2 psig from the lower limit of the manufacturing design range prior to calculating the operating ratio. Contact OsecoElfab for support in selecting an operating ratio for burst pressures below 15 psig.

What is the lifespan of a ruptured disk?
We hear many customers ask this question and it really is a good one. Generally speaking rupture disks have an indefinite shelf life,
however, there are storage conditions to consider that could affect the performance of the disk once it’s installed.
