Home > Spiral Wound Gasket
DESCRIPTION:
Spiral Wound Gasket is formed of V-shaped metallic stripe and soft non-metallic filler by means of piled, spiral wound and connected its end and beginning by dot welded. Depend on its excellent compression resilience it is suitable for sealing spots where the alteration of temperature and pressure are frequent.Support rings,inside and Outside the spiral,improve the gasket's handing,fitting and Versatility.It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical, mechanical manufactory, power station, metallurgy, shipbuilding, medical and pharmaceutical nuclear power station and navigation, etc.
We can produce according to ASME, BS, JIS and EN(DIN) standards or client request.

SW110-R 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.
|
|
SW110-IR 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.
|
|
SW110-CG 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.
|
|
SW110-CGI 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.
