It solves the problems caused by insufficient elasticity of the seal. Also suitable for applications with low initial tightening torque.
POWERgasket - sealing for non-flush surfaces solves problems caused by insufficient elasticity of the seal and prevents leakage of pollutants. Also suitable for applications with a low initial tightening torque or where flange cooling and heating are involved.
The functional parts of this seal consist of two corrugated metal cores that are coated with flexible graphite of varying density and thickness. The gaskets thus produced are attached to a metallic intermediate ring.
The wavy shape increases the ability to return to its original state and reduces the surface area of the seal at the beginning of tightening. It also reduces the amount of seating pressure required to make the seal functional. This results in bolt stability and increased stability of contact force during temperature cycles.
The manufacturing process of applying graphite to the surface of the metal core ensures that it is applied without the pores found in graphite plate gaskets.
Normally, graphite is applied to the metal core in only one density and thus the gasket provides the advantages of only this one density.
