Kammprofile Gaskets

Kammprofile gaskets consist of a metal core (generally Stainless Steel) with concentric grooves on either side with sealing materials. The sealing layers (depending on the service duty) can be Graphite, PTFE (Teflon), CAF or Metal (e.g Aluminium or Silver). Kammprofile's can be used without sealing layers to provide an excellent seal but there is a risk of flange surface damage.

The very wide seating stress range (minimum to maximum stress) of the Kammprofile gasket makes it

  • Highly suitable for varying temperatures and pressures.
  • Less senstive to assembly faults (inaccurate bolt tensioning).
  • Suitable for light and heavily constructed flanges.
  • Dependent on layer material Kammprofile gaskets are resistant to temperatures up to 1000 0C.
  • Resistant to media pressures up to 250 bar.

The additional benefits are

  • When assembled the layer thickness of the sealing material is extremely small (0.5mm) thus reducing leaks, reject rates and environment pollution.
  • The gasket will not damage the flange surface and can be easily removed.
  • Reduces maintenance costs.
  • Emergency sealing of damaged flanges by using 1mm thick sealing layers until the flange can be reworked.
  • Flange face protection Kammprofiles wil not damage the flange faces even at extreme seating load.
  • Excellent performance when subject to fluctuating temperatures and pressures.
  • Direct replacement for existing gaskets. No special flange finish is necessary.
  • Eco-friendly by significantly reducing leakage into the atmosphere.

Flange surface Finish

The recommended flange surface finish for Kammprofiles with sealing layers is from 125-250 RMS.

Loose or Integral rings

Thermal-shock conditions may damage Kammprofiles with integral centring rings (thermal tension may cause cracks in the core).

SEALING LAYER MATERIALS AND SEALING STRESSES

The following table gives information regarding different types of materials offered as sealing layer materials by IGP. Also given is recommended seating stress range for reliable and effective performance:

Material Temp (Deg.C) Max.Operating
Pressure(Bar)
Gas Tightness Application Seating Stress
Min Max Min (N/mm2) Optimum (N/mm2) Max (N/mm2)
Graphite -200 550 250 Good Aggressive Media 20 90 400
PTFE 200 250 100 Good Aggressive Media 20 90 400
CAF -150 450 100 Moderate Liquids 65 161 400
Silver -200 750 250 Good Aggressive Media 125 240 450

CORE THICKNESS

When a Kammprofile is replacing an existing gasket (eg. spiral wound gasket); IGP recommends 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.

Pipe system Core thicknes Seated Thickness (Core + 2 sealing layers)
Existing 4mm 5.0mm to 5.2mm
New -5mm 6.0mm to 6.2mm
