Spiral wound gaskets are to be constructed as alternate plies of preformed metal windings and plain fillers that are spirally wound when compressed between two flanges. A "v" and "w" shaped crown centered in the metal strip acts as a spring, giving gaskets greater resilience under varying conditions. Filler and strip materials can be changed to accommodate different chemical compatibility requirements. If the load available to compress a gasket is limited, gasket construction and dimensions can be altered to provide an effective seal.
A spiral wound gasket may include a centering ring, an inner ring or both. The outer centering ring enters the gasket within the flange and acts as a compression limiter, while the inner ring provides additional radial strength. The inner ring also reduces flange erosion and protects the sealing element. Resilience and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications. Widely used in refineries and chemical processing plants, spiral wound gasket are also effective for power generation, aerospace, and a variety of valve and special applications. The spiral wound gasket industry is looking for change in the specification covering spiral wound gasket. As environmental regulations and industry requirements become increasingly stringent, new and custom applications are continuing to evolve. Wherever you need a strong, resilient seal, our spiral wound gaskets provide an effective solution.
TYPE OF SPIRAL WOUND GASKET| SW - Basic Type
Basic construction type, inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics. - Suitable for tongue and groove, male and female or grooved to flat face flange assemblies. |
|
| SWI -
Inner Ring Type
Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion, damages of gasket between flange bore and the inside diameter, the annular space is filled up by solid inner metal ring. - Suitable for male and female pipe flanges. |
|
| SWC -
Outer Ring Type
Solid outer ring accurately locates the gasket on the flange face to give the additional radial strength to prevent the gasket blowout and acts as a compression limiter. In case of installing the outer ring, it is very easy to install the gasket to flange face because the end of outer ring will touch at bolts - Suitable for use with flat face and raised face flanges. For class **0 and above an internal ring is recommended. |
|
| SWCI -
Inner & Outer Rings Type
A inner ring and outer ring type gasket will give an additional compression limiting stopper for gasket inner and outer side. It will prevent the corrosions on flange face at annular space. - Suitable for use with flat face and raised face flanges and specified for high pressure / temperature service - Class **0 and above or where corrosive or toxic media are present. |

Flexible
graphite has been carefully researched and developed to meet
industry's demand for a superior alternative to asbestos filler in
spiral wound gaskets. Flexible graphite provides performance that
is superior to asbestos, and has been field proven through year of
actual service in critical applications throughout the world.
Flexible graphite is pure graphite and is manufactured without the
use of filters, resins or binders that could deteriorate at
elevated temperature.
PTFE : If PTFE is subjected to temperatures above **0 composition
starts to occur slowly, increasing rapidly above **0.
Care should be taken to avoid inhaling the resultant fumes, which
may produce unpleasant effects.
Our production is in compliance with the standards of ASME B *6.*0, MSS SP**4, API **5, DIN, JIS, JPI, BS ***0, JG / T, GB / T, HG, SH, etc. Or products can be customized according to the users’ requirements. Please provide the specific drawings if the gasket is used in the heat exchanger with ribs.
