SPIRAL WOUND GASKET (SWG)

SHAPES:
OBROUND, SQUARE, PEAR, OVAL, DIAMOND, ROUND.

TYPES:
Basic, Inner Ring, Outer Ring, Outer-Inner Ring

SWG - Basic Type GINDO No. 690

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.

 SWG BASIC GINDO

SWG - Inner Ring Type GINDO No. 691

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.

 SWG INNER RING

SWG - Outer Ring Type GINDO No. 692

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.

 SWG OUTER RING

SWG - Inner & Outer Rings Type GINDO No. 693

An 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.
