A rupture disc is installed on a pressure vessel or a pipe line and gets ruptured when the pressure exceeds the safety limit or the regulatory limits, so that the overpressure can be discharged to a safe place and the pressure vessel and the pipe line can be protected from damages
ο The POPF (Flat Composite) rupture disc consists of the three confi gurations of the pressure disc, the sealing sheet, and the vacuum disc.
ο It is the type broken by the internal pressure of fl uid with the burst part intentionally processed by the burst design value.
ο It can be used widely in all areas such as gas, liquid, and steam.
ο The holder is not needed. It is installed between the standard or nonstandard companion fl anges. The compression non-asbestos or Tefl on gaskets are attached to both sides of the rupture disc.
ο It is the type suitable to the application of low and fi ne pressure.
ο The holder is not needed so that the price is the cheapest.
ο The burst area and rated capacity are more excellent than any other model.
ο The precision processing is possible to apply setting and bursting pressure. The tolerance range is possible up to ±3%.
ο Tefl on (PFA) is mainly used for the sealing sheet preventing liquid leakage.
ο 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.)
ο Manufacturing is possible with the R.F or F.F type according to the fl ange specifi cation.
ο It is the type resisting the full vacuum by applying the vacuum support if needed.(Optional)
ο It is the multi-layered structure type with the burst part processed by the burst design.
ο The disc rupture can be monitored in the control room by applying the alarm sensor system. (Optional)
