Spiral Wound Gaskets
Design
Notion Spiral Wound Gaskets consist of a V-shaped metal strip spirally wound in combination with a soft filler material. This construction helps maintain an
effective seal at high fluctuating temperatures and pressures. The metal strip provides outstanding recovery, while the flexible filler guarantees excellent
sealing. Depending on the application, the spiral wound gasket can be specified with outer and/or inner rings.
Application
A Spiral Wound Gasket is the most widely used in a wide range of applications: piping, heat exchangers, pressure vessels, petrochemical, Valves, nuclear and marine plants etc. involving a range of pressure and temperatures. They are used in industrial sectors like Refineries, Power Plants, Pipeline Construction, Petro-Chemical Process Plants and Fertilizer Plants etc.
Gasket Style
The correct style of gasket should be selected from the list below.
TYPE-R : Type R is a sealing element only where controlled compression must be in the flange. Inner and outer
diameters are reinforced with several plies of metal, without filler, to give greater stability and sealing.
TYPE-RIR : Type RIR gaskets are produced with a sealing element and an inner ring.
TYPE-RCG : Type RCG are produced with a sealing element and an outer ring.
TYPE CGIR : Type CGIR includes inner and outer rings with the element component of the gasket for an additional compression limiting stop. For use with flat face and raised face flanges, Type CGIR features increased compressive force for blow-out prevention and is specified for high pressure/ temperature service or where corrosive or toxic media are present.
TYPE-RON : Type RON gaskets are produced with a sealing element and an Outer Nose. This Type of gaskets ideal for large diameter heat exchanger.
TYPE-ONIR : Type ONIR includes inner ring and outer nose with the sealing element, the inner ring prevents over compression of the sealing element.
