What is SS 316L Kammprofile Gasket
SS 316L Kammprofile gasket consists of a SS 316L metal core with concentric grooves on either side with sealing materials. The sealing layers (depending on the service duty) can be Graphite, PTFE (Teflon), Non-asbestos. Kammprofile gasket can be used without sealing layers to provide an excellent seal but there is a risk of flange surface damage.
Typical Applications
The very wide seating stress range (minimum to maximum stress) of the SS 316L Kammprofile gasket makes it highly suitable for varying temperatures and pressures., Less senstive to assembly faults, suitable for light and heavily constructed flanges. Dependent on layer material SS 316L Kammprofile gasket is resistant to temperatures up to 1000°C and media pressures up to 250 bar
The additional Benefits and Advantages
When assembled the layer thickness of the sealing material is extremely small (0.5mm) thus reducing leaks, reject rates and environment pollution. The SS 316L Kammprofile gasket will not damage the flange surface and can be easily removed and it also reduces maintenance costs. Flange face protection Kammprofiles will not damage the flange faces even at extreme seating load. SS 316L Kammprofile gasket has excellent performance when subject to fluctuating temperatures and pressures. It is a direct replacement gasket for existing gaskets, no special flange finish is necessary. SS 316L Kammprofile gasket is an eco-friendly gasket by significantly reducing leakage into the atmosphere. The recommended flange surface finish for Kammprofile gasket with sealing layers is from 125 to 250 RMS.
SS 316L Kammprofile Gasket with Loose or Integral rings
Thermal-shock conditions may damage Kammprofiles with integral centering rings (thermal tension may cause cracks in the core).

Metal Core thickness of Kammprofile Gasket
When a Kammprofile gasket is replacing an existing gasket such as spiral wound gasket, we recommend a 4mm thick core to prevent unnecessary stresses on existing pipe lines. For new system, we recommend 5 mm thick cores. The value should be taken into account at the design stage.
