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.
