S.P.A.C. EN 1591/98 (Sealing Pressure Assembly Calculation) is the software program used for the Sealing Pressure Calculation of every kind of flanged joints based on the new European Standard EN 1591/98 that introduces modifications in calculations according to the Taylor method.

The database of this program allows to chose the geometry (gaskets, flanges, bolts, etc.) and the materials of the joints, and once the service conditions have been introduced, the program prepares the design and evaluates the results both numerically and graphically, recommending the right tightness.

Differences between the temperature of flanges and bolts.

Lack of joint linearity.

Creep deformation of the joint.

External forces and momenta.

Bolt tension deviations.

Changes of the joint force under mechanical load in process.

The calculation offers a recommendation that fits with the empirical data, allowing to research on the optimization of the sealing design both in existing joints and in flanged joints that are currently being designed.

It is possible to offer the software or the calculations already done for your flanged joint.
