Spiral Wound
Gasket is the ideal gasket in the semi-metallic category.
A narrow strip of V-shap metal hoop is spirally wound under
tension with a filler cushion between the lami nation of the
metal and is spot-welded at both ends.
This unique construction of a spring-like
metal and soft filler provides gasket excel-lent 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.
