SPIRAL WOUND METALLIC GASKETS

Novus 5G sealing products
Champion Spiral Wound Gaskets are composed of a metallic continuous strip with a special shaped profile, coupled with a continuous filling strip (Asbestos, PTFE, Graphite etc.) evenly wound in concentric spiral under constant stress. The Spiral Wound Gaskets are reinforced on the inner and outer diameter by winding of several electrically welded metal.

The main property of Spiral Wound Gasket, owing to elastic action of the special metallic strip profile, is that of offering a perfect sealing under fluctuating pressure and temperature conditions & maintaining tight elastic recovering. This elasticity can be modified by a proper selection of components. A proper selection of materials (both metal and fillers) allows the spiral gasket to accommodate the most varied operating conditions.

Spiral Gaskets are made as per ASME B16.20 to suit ASME B16.5 flanges and as per "A" Series and "B" Series to suit ASME B16.47 flanges. We also make spiral as per DIN 2632-2638, IS Standards, etc.
