CORRUGATED GASKETSThe gasket consists 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. Great very high tightness (σVU 0,01 = 22 MPa) is already achieved at very low surface stress. Further features of the gaskets are good adaptability and elastic recovery properties, blow-out safety, good stability and manageability.
Corrugated metallic gaskets have their advantage when it comes to rising and ebbing pressures and temperatures, flexible or contorted flange sealing faces as well as for low surface stress. The gaskets can be fabricated in ring, oval, elongated oval and rectangular frame shapes. GASKET PROFILES:
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. MATERIALS USED FOR CORRUGATED GASKETS
