The rupture disc shown in Figure 6-26 is a two-way version of
graphite rupture discs. The discs are custom-produced in sizes DN 25
(NFS 1) through DN 600 (NPS24). The maximum burst pressure in
either direction is 10 bar (150 psig). The minimum pressure differential
between the two burst pressure ratings must be 0.7 barg (10 psig),
depending upon diameter and rating of the rupture disc.
