Spiral Wound Gaskets

SPIRAL WOUND GASKET OFFERS HIGH COMPRESSIBILITY AND RECOVERY
Spiral Wound Gasket is composed of a steel outer ring, a spiral wound sealing strip filler and a special steel inner ring. It is created by winding alternating strips of metal and filler material.

Outer guide ring is fitted to centralise the gasket between the bolts and to act as a compression limiter. Inner ring is fitted to reduce the gap between the inside diameter of the gasket and the bore of the flange.

It is widely used in moderate to critical services in various industries. They are most suitable for the gaskets subject to extreme temperature or pressure cycling, shock or vibration. These gaskets have the best resistance property when compare with other metal and asbestos type gaskets.

TYPES

Centering gasket (Style CG). Utilizes an external ring which accurately centers gasket on flange face. It provide an additional radial strength to prevent the gasket blow-out and acts as a compression stop. A general purpose gasket suitable for both flat face and raised face flanges.
Centering gasket with inner ring (Style CGI). This style is similar to style CG, but it additionally consists of an inner ring. The outer ring is used for centering and the internal ring used as an additional compression limiting stop. The internal ring also serves as a barrier to protect the gasket from heat and corrosion.
Reinforced spiral wound gasket (Style R). It is a basic configuration of spiral wound gasket. The Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics.
Reinforced inner ring spiral wound gasket (Style RIR). This style of the gasket, the solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. It is designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces.

Spiral wound gaskets are produced in several style and combination of meterials to fit the most stringent application. Spiral wound gaskets are usually of circular shape, however we can produce them in other shapes such as: oval, rectangular, with round corners, etc. Our standard production program comprises a range of spiral wound gaskets with inner diameters of 10mm to 3000mm and non-standard dimensions and shapes, and larger diameters are available on request.
