Gaskets
A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Metallic Gaskets: \"Metallic Gaskets\" are gaskets that are fabricated from one or a combination of metals to the desired shape and size. Common metallic gaskets are Spiral Wound Gaskets, Double Jacketed Metal Gaskets, Solid Metal Gaskets, Corrugated Metal Gaskets, Ring Type Joint Gasket used for heat exchangers, compressors, condensers, pumps, valves and turbines. These metallic gaskets are suitable for high pressure & temperature applications and require high bolt load to seal. Types: � Spiral Wound, Double Jacketed, Solid Metal gaskets, Corrugated Metal Jacketed Gaskets, Ring type joint Gaskets Non Metallic Gaskets: \"Non Metallic Gaskets\" or \"Soft Gaskets\" are gaskets that are easily compressed under a low bolt load. They are composite sheet materials that are suitable for a wide range of general as well as corrosive chemical applications. They are easily available either in sheet form or as gaskets that are cut accurately to any reasonable shape and size. Non metallic gaskets are usually manufactured from materials like arimid fiber, glass fiber, elastomers, teflon (PTFE), compressed asbestos fibre (CAF), flexible graphite etc. Types are: Non Asbestos, Asbestos, Flexible Graphite, PTFE, Viton, Silicone Rubber, Neoprene and Flange Gaskets.

[Spiral Wound Gasket] Material Filler: GRAPHITE, PTFE, INCONEL, etc. Hoop: SUS304, SUS316L, etc. Feature The spiral wound gasket is the most ideal type having flexibility and recovery which are essential for high temperature and high pressure among semimetal gaskets. It is wound in spiral combined with V-type metal thin hoop and non-ferrous material filler. The winding start part and end part are wound by the hoop over several times and then both edge is processed by spot welding to make the gasket. The gasket has outstanding capability as it features unique structure with elastic metal and flexible filler. - Outstanding capability for high temperature and high pressure - Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditions - Efficient production for any type of dimensions such as round or oval type, etc. - Outstanding sealing capability as it is produced according to the pressure of unbalanced flange. - Hoop and Filler materials can be selected according to special operating conditions.

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. https://www.forseall.com/ 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. Three centering gaskets with black inner ring on a white background.

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.
