CALCULATION SERVICE KEMPROOF® PRO

the free online calculation program for screw tightening torques

We support our customers comprehensively and according to their needs in the calculation of sealing joints: with our free online program KemProof for the calculation of screw tightening torques as well as with complex analyses according to project-specific specifications.

On our website www.klinger-kempchen.de we offer our customers the free calculation the tightening torques of screws in 5 simple steps.

The program supplies the tightening torque of the bolts taking into account:

  • DIN, ANSI flange type
  • Additional loads
  • Screw type and screw material
  • Pressure
  • Temperature
  • Required leakage class
  • Coefficients of friction
  • Seal type

If necessary, a check calculation according to DIN EN 1591-1 is possible, provided that DIN EN 1092-1 flanges are used. Further data such as flange material and nominal calculation tension are taken into account.
In addition to the torque, the calculation also provides the optimum load factors of flanges, bolts and gaskets as well as the flange blade inclination.
If the maximum flange blade inclination is exceeded, the program signals this. For the calculation of the torque, the minimization requirement of VDI 2290 is taken into account.

Of course the free online calculation is also available on your smartphone. This means you can use our service anywhere, for example directly at the installation site.
