gasket in the semi-metallic category. A narrow strip of V-shape
metal hoop is spirally wound under tension with a filler cushion
between the lamination of the metal and is spot-welded at both
ends.
This unique construction of a spring-like metal and soft filler
provides gasket excellent characteristics. Resistance to high
temperature and high pressures. Great resilience which allows the
gasket to adjust automatically to change in operating conditions,
such as pressure and thermal shocks, vibrations etc.
Excellent sealability is maintained with comparatively small gasket
area.
Good tolerance for flange surface finish irregularities.
Can be designed to any dimensions economically in circular or
moderately noncircular shape.
Available in a variety of hoop metals and filler materials to
satisfy specific operating conditions.
