Explanation

  • The POPSR (Reverse Buckling Scored) rupture disc is manufactured with the design of the precise line or mark generation. It is the reverse dome type broken by tension if the setting pressure generated with the precise design is reached.

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

  • It is the type enduring the back pressure, vacuum, and pulsation well.

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

Properties

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

  • The burst area and rated capacity are excellent. It is the solid disc type. It has the excellent safety grade. It can be applied widely in the high temperature. It uses comparatively thick materials so that it excels in resisting corrosiveness.

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

  • It is the type not requiring the vacuum support and the knife.

  • It is the single-layered structure type formed by the rupture design.

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