| Message: | 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. |
