Spiral wound gasket
The design of spiral wound metal gaskets features a specific property profile, which predestines them for use in high-pressure applications.
Particularly of interest is the high temperature application limits (550°C graphite), pressure limits during application (320 bar) and excellent recovery rates.
The fully confined version of the spiral wound metal gasket with inner and outer ring can cope with high seating stress.
The elongation differences of the flanged joint components - particularly at fluctuating pressure and temperature conditions - result in a shifting sealing gap, which can be compensated by the resilient characteristic of the spiral wound gasket and provides a safe seal in these conditions.
