CAMPROFILE GASKET

Specifications

Camprofile 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). Camprofile's can be used without sealing layers to provide an excellent seal but their is a risk of flange surface damage.The very wide seating stress range (minimum to maximum stress),. 

camprofile gasket makes it: highly suitable for varying temperature and pressures. less senstive to assembly faults (inaccurate bolt tensioning). suitable for light and heavily constructed flanges,.

 Dependent on layer material camprofile gaskets are resistant to temperatures    up to 1000 degree C 
 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 Camprofiles 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 significant reducing leakage into the atmosphere,.
Flange surface 

finish The recommended flange surface finish for camprofiles with sealing layers is from 125-250 RMS,

oose or Integral rings

Thermal-shock conditions may damage camprofiles 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 for reliable sealing purpose,.

CORE THICKNESS
When a camprofile 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 of the design stage. 
Pipe system Core thickness Seated Thickness (Core + 2 sealing layers)
Existing New 4mm 5mm
