Rupture Discs                       229

          in which growth of polymer  could  start. A rupture disc  device that  meets
          this requirement  is shown in Figure  6-11. By implication,  the rupture  disc
          cannot  be used  in polymerization  service when  being  fitted  with  a vacu-
          um  support.
            Figure  6-12  and  Figure  6-13  show  two  types  of  slotted  and  lined  flat
          rupture discs  that may be used for either one-way  or two-way flow.
