The Phoenix Alba-Shield is a fire-safe spiral wound gasket designed to mitigate flange face corrosion. The gasket comprises a specially configured dual seal spiral sealing element with a PTFE faced metal inner ring. The primary inner gasket ensures inert, non-reactive sealing from the bore of the flange.
The Phoenix Alba-Shield was created in response to an industry-wide increase in flange face corrosion and its effects. It is designed as a standard pipeline gasket in any grade of raised faced steel flange, and in any application where conventional spiral wounds have been previously used. The Alba-Shield is firesafe as standard, seals tighter to reduce leaks, and performs to a higher level than a conventional spiral wound gasket.AlbaShield Datasheet
