Metallic corrugated gaskets

The Corrugated gaskets consist of a stainless steel wave stainless steel plate with a graphite foil seal seat on both sides. The graphite layers and metallic core profile are adjusted in such a way that a wave crest overlap of 0.1 to 0.2 mm is guaranteed in the restraint condition. This achieves a very low diffusion cross-section. In addition, there is also a high density of the graphite in these areas.

Very high tightness (σVU 0,01 = 22 MPa) of the Corrugated gaskets is already achieved at very low surface stress. Further features of the Corrugated gaskets are good adaptability and elastic recovery properties, blow-out safety, good stability and manageability.

GASKET DIMENSIONS AND SHAPES

Shapes of corrugated gaskets can be circular, oval, rectangular, etc. Dimensions of the gaskets are available from 50 mm to 4000 mm according EN or ASME standard or in non-standard dimensions according to customer's request.
