Spiral-wound gaskets have become extremely popular due to the wide variety of available styles and sizes. Spiral-wound gaskets can be fabricated of any metal which is available in thin strip and which can be welded; therefore, they can be used against virtually any corrosive medium dependent upon the choice of the metal and filler. They can be used over the complete temperature range from cryogenic to approximately 2000°f. This type of gasket can be used in all pressures from vacuum to the standard 2500 psi flange ratings.
