CORRUGATED METAL GASKET – COVERED WITH GRAPHITE OR PTFE LAYER
Corrugated metal gasket (CMG) consists of a metal core with concentric grooves on both sides and coated with expanded graphite, PTFE layer or non-asbestos plate.
Corrugated metal gasket with soft layer on both sides is used for low pressure applications in large diameter flue gas ducts at high temperature. In addition, corrugated metal gasket is a versatile sealing element when bolt loads are low.Unlike other materials and structures, it can be very resilient.
What's more, corrugated metal gasket directly replaces spiral wound gasket and eliminates inward buckling issues while creating a seal at moderate flange stresses.
