Product Description

Spiral wound gasket is formed of V-shaped metallic strip and connected its end & beginning by DOT welded. Depending on its excellent compression resilience, it is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal excahnger, condensing tower, plain hole and man hole of flange, etc. Please offer the detailed drawing, while the gasket is used in thermal exchange if with some ribs.

Spiral Wound Gaskets consist of a spiral wound sealing component with a solid metal outer guide ring. The outer guide ring serves to center the gasket properly in the flange joint, acts as an anti-blowout device, provides radial support for the spiral wound component, and acts as a compression gauge to prevent the spiral wound component from being over crushed. Normally the outer guide rings are furnished in mild steel, but can be supplied in other metals when required by operating conditions.

The inner ring also serves several functions. Primarily, it provides radial support for the gasket on the winding inside diameter(ID) to help prevent the occurrences of buckling or imploding. The inner ring also serves as an additional compression limiter.

Its ID is normally sized slightly larger than the ID of the flange bore, minimizing turbulence in process flow. The inner rings are normally supplied in the same material as the spiral wound component. Rilson normally manufactures standard spiral wound gaskets to ASME B16.20, designed to suit ASME B16.5 and ASME B16.47 flanges.
