Description:Spiral wound gasket is formed of V-shaped Metallic strip and soft non-metallic filler. Support rings, inside and Outside the spiral, improve the gasket's handing, fitting and Versatility.
Depend on its excellent compression resilience, it is suitable for sealing spots where the alteration of temperature and pressure are frequent.

Types:


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.

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.

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 900 and above an internal ring is recommended.

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 900 and above or where corrosive or toxic media are present.

Typical Applications:
Pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc.
Petrochemical, chemical, mechanical manufacturer, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear power station and navigation, etc.

Prime Features:
> Gasket are made in a wide variety of sizes and shapes.
> Combinations of metal strip and filler are selected to suit the specific fluid media and operating conditions.
> Quick to install and remove
> Make gaskets suitable for high pipeline pressure on flat or raised flange faces.
> Temperatures from cryogenic up to 1000 º C

Specifications:
