Explanation

  • The POPC (Dome Composite) rupture disc consists of the three confi gurations of the pressure disc, the sealing sheet, and the vacuum disc.

  • It is the type broken by the internal pressure of fl uid with the burst part intentionally processed by the burst design value.

  • It can be used widely in all areas such as gas, liquid, and steam.

  • It should be mounted with the standard holder of our company for use.

Properties

  • It is the type suitable to the application of low and middle pressure.

  • The burst area and rated capacity are more excellent than any other model.

  • The precision processing is possible to apply setting and bursting pressure. The tolerance range is possible up to ±3%.

  • Tefl on (PFA) is mainly used for the sealing sheet preventing liquid leakage.

  • The material quality of the sealing sheet can be applied variously according to the temperature and corrosiveness of fl uid. (PFA, PTFE, FEP, SUS316L, Nickel, Monel, Inconel, etc.)

  • It is the type resisting the full vacuum by applying the vacuum support if needed. (Optional)

  • It is the multi-layered structure type with the burst part processed by the burst design.

  • The disc rupture can be monitored in the control room by applying the alarm sensor system. (Optional)
