Explanation
- 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.
- 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.
- It can be used widely in the gas, steam, and liquid areas.
- It is the type enduring the back pressure and vacuum well.
- It should be mounted with the standard holder of our company for use.
Properties
- It is the type suitable to the application of fi ne and low pressure.
- It is the solid disc type. It has the excellent safety grade. It excels in resisting
high temperature and corrosiveness.
- The disc material quality can be applied variously according to the
temperature and corrosiveness of fl uid.
(SUS316L, Nickel, Monel, Inconel,
Titanium, etc.)
- The burst area and rated capacity are excellent. It is the multi-layered
structure type formed by the burst design.
- The disc rupture can be monitored in the control room by applying the
alarm sensor system. (Optional)
