Gasket design
The basis is the proven gasket material AFM 34 (see also Technical Datasheet No. 334), which is covered with a new coating (CO) to optimize the surface adaptation.The metal inner bead of 0.10-mm-thick stainless steel 1.4571 is manufactured using a special beading process.

Properties
  • maximum gas seal even at low surface pressures
  • optimal prerequisites for the calculation of flange joints under EN 1591-1 to maintain sealing class under VDI 2290
  • low load absorption of the inner bead (optimized surface pressure distribution)
  • blow-out proof
  • high chemical resistance

Inner bead
  • Stainless steel 1.4571; 0.10 mm
  • ≤ DN 400 seamlessly finished; > DN 400 welded

The data quoted above are valid for the material "as delivered" without any additional treatment. In view of the countless possible installation and operating conditions, definitive conclusions cannot be drawn for all applications regarding the behaviour in a sealed joint. Therefore, we do not give any warranty for technical data, as they do not represent assured characteristics. If you have any doubt, please contact us and specify the exact operating conditions.
