Selection Guidelines
1. The Rupture Disc pressure setting should be the same as the Henry
Technologies’ Pressure Relief Valve setting.
2.
3. The stamped burst pressure is subject to a manufacturing tolerance of +/-
5%. This tolerance should be taken into account when specifying a
Rupture Disc setting (refer to table).
The stamped capacity of a spring loaded Pressure Relief Valve when
installed with a Rupture Disc between the inlet of the valve and the vessel
shall be multiplied by a factor 0.90 of the rated relieving capacity of the
Pressure Relief Valve alone.
4. It is recommended that the maximum operating pressure of the system is
no more than 70% of the stamped burst pressure, in order to minimize the
risk of premature fatigue failure of the disc. If operating pressures exceed
90% of the stamped burst pressure, the Rupture Disc should be replaced
immediately.
5. The design fatigue strength of each Rupture Disc is 100,000 pressure
cycles. Fatigue life will be reduced by excessive pressures or
temperatures, corrosion, damage, etc.
