FLEXPRO GASKETS (PDF)

The Flexpro (formerly known as the Kammprofile) gasket offers a safe, effective seal under the most severe operating conditions on both standard pipe work and special applications. The Flexpro gasket offers excellent flexibility and recovery characteristics, allowing seal integrity under pressure and temperature fluctuations, temperature differential across the flange face, flange rotation, bolt stress relaxation and creep.

The Flexpro is a two part assembly, consisting of a precision serrated metallic core with the addition of soft gasket sealing materials bonded to either face (usually graphite). Although the soft gasket sealing material provides initial low stress gasket seating, the serrated geometry of the metallic core enhances sealing performance by means of inducing stress concentration on the sealing layers while containing these sealing faces within the radial grooves. This minimizes lateral flow and ensures the applied load is confined upon the gasket sealing faces. A further function of the metallic core is to provide exceptional gasket rigidity and blow out resistance, as well as offering an integral compression stop. Flexpro gaskets are suitable for Class 150 to 2500 service.
