POPRK

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 POPRK (Reverse Buckling Knife-Shear) rupture disc is manufactured with the reverse dome type shape. The disc is reversed, cut, and broken by the saw-toothed knife blade in the upper part of the disc.

    ο  The knife-blade cuts through the rupture disc without fragments in one direction. It is the type without contamination generated by the metal in the process.

    ο  It can be used widely in the gas, steam, and liquid areas.

    ο  It is the type enduring the back pressure and vacuum well.

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

ο  It is the type suitable to the application of fi ne and low pressure.

ο  It is the solid disc type. It has the excellent safety grade. It excels in resisting high temperature and corrosiveness.

ο  The disc material quality can be applied variously according to the temperature and corrosiveness of fl uid.
(SUS316L, Nickel, Monel, Inconel, Titanium, etc.)

ο  The burst area and rated capacity are excellent. It is the multi-layered structure type formed by the burst design.

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