Audited Supplier Kammprofile Gasket (Serrated Metallic Gasket) consist of a metal core, generally stainless steel with concentric grooves on both sides. A sealing layer is usually applied on either side and depending on the service duty the material for this layer can be expanded graphite, PTFE, Asbestos free gasket sheeting materials or some soft metal. It can be used without sealing layers to provide an excellent sealing but there is a risk of flange surface damage especially at high seating pressure.
n 620 Basic Type Kammprofile Gasket
n 620 JR Kammprofile Gasket with integral Outer Ring
n 620 SJ Kammprofile Gasket with Loose Outer Ring
Depending on centering ring with cheaper material (Normal: CS) and thinner thickness (Normal: 1.5mm) for Style 620 SJ, maybe it is more economical than 620JR.
Application
Kammprofile gasket is the preferred gasket when improved performance at low seating stresses is required. It features excellent anti-blow-out properties linked with the reliably of a solid metal-to-metal seal combined with a soft sealing face to provide a tighter joint. It is particularly suitable for applications where high temperature, pressures and fluctuating conditions are encountered. Non-metal cover layers ensure that flanges are not damaged, even at extreme loads. This gasket is an ideal replacement for problem applications associated with jacketed gaskets, for heat exchangers, vessels and reactors and various flange connections. Pressure: (6.4~25Mpa).
