Rupture disk discharge piping sizing
The sizing of the rupture disk discharge piping must not be less than the rupture disk diameter.
Where two or more relief devices are connected to a common line or header, the effect of back-
pressure that is developed when more than one relief device operates, must be considered. The
sizing of the discharge line for the outlined condition must be based on the sum of each rupture
disk outlet area in addition to the pressure drop allowance through the outlet piping.
