KemAnalysis is a process for the analysis of sealing surfaces and for the estimation of the partial surface pressure distribution.

In practice, flanges are found that demonstrate various faults in the contact surface to the gasket. Whether they constitute se­vere damage depends upon the impact on the locally present surface pressure.
For instance, the following faults can be detected:

  • Unevenness in the flange caused by corrosion (planar ero­sion and/or pitting corrosion)
  • Scratches that run from the inside to the outside, e.g. caused by cleaning the flange using scrapers or brushes that are harder than the flange material.
  • Depressions in the outer area of the sealing strip, caused by setting tools during the assembly or dismantling of the gasket.
  • Partial indentation points in the centre of the sealing sur­faces.
  • and much more.

KemAnalysis facilitates an estimation of this situation. The con­nection between the deformation and applicable surface pres­sure is established by visualising the unevenness as a com­pression in the graphite layer and simultaneously illustrating the surface pressure by means of pressure-sensitive paper.

KemAnalysis is assembled in the same manner as a normal gasket. The special coating securely holds the measuring de­vice together and protects the sensitive measurement paper against chemical attack. The analysis can then begin immedi­ately. Either by means of a purely visual estimate or with the aid of a software-supported surface analysis.
