Standard rupture discs are available from stock in burst
pressures as listed in the chart below. All pressures
through 15,000 psi are shaded. These discs are 316
stainless steel (except for 1,000 psi which are inconel)
and may be used with any of the safety heads shown.
Note that these rupture discs are supplied with a range
of plus 6% and minus 3% of specified burst pressure.
Samples of each batch are then tested and typically
the actual average burst pressure is stamped on an
accompanying metal tag. There is a +/- 5% burst
tolerance applied after the burst pressure has been
established. Factors influencing rupture =disc life
include corrosion, metal fatigue, and cyclic effects.
Periodic replacement is recommended to prevent
