Spiral
wound gasket is manufactured by spirally winding
a pre-formed metal strip and filler on the outer
peripery of metal winding mandrels. The winding
mandrel outside diameter forms the innner diameter
of the gasket and the lamination are continually
wound until the outer diameter is attaineds.
The inner and outer diameters is reinforced with
several plies of metal with no fillers being introduced.
This gives greater stability and provides better
compression and sealing characteristics. Then by
varying the ratio of the filler to the metal plies
for a given gasket width density, and hence the
compressibilty, can be controlled.
1. Spiral wound gasket without inner and outer ring
suitable for tongue and groove flange and narrow
width flange.
2. Spiral wound gasket with outer ring which accurately
centers gasket on flange and acts as compression
stop.
3. Spiral wound gasket with inner and outer ring,
innner ring gives an additional compression limiting
stop and provides heat and corrosion barrier protecting
gasket winding and flange erosion.
4. Spiral wound gasket with metal jacketed partition
bar welded to spiral wound gasket for use on heat
exchanger. |
