The sealing element of the spiral wound gasket consists of a vshaped
metal strip spirally wound in combination with a soft sealing
material filler. The metal strip provides outstanding resilience, while
the flexible sealing filler guarantees excellent
sealing. Due to this combination of materials the spiral wound gasket
is suitable for sealing under severely fluctuating temperature and
pressure conditions. Depending on the application the spiral wound
gasket can be specified with outer and/or inner rings.
Mainly used for male and female flanges or projection and recess
flanges. The inner ring is necessary as a compression
stop.
The spiral wound gasket is suitable for use across a wide pressure range and is therefore virtually applicable.
The spiral wound gasket can be used to seal fluid pressures up to 250 bar and damage (although extra care should be taken during transportation and installation of large diameter gasket without guide rings).
The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out.
By combining different winding materials and metals the gasket can be tailored to a wide variety of operating conditions.
Due to its non-adhesive character the gasket is easy to remove after service.
The gasket does not cause damage to the flange faces
