Spiral Wound gaskets, ASME B16.20 Metal Gasket
The concept of spiral wound gasket construction was pioneered by Flexitallic in 1912, inaugurating the beginning of a new era in safe, effective sealing. The primary purpose for this development was the increasingly severe temperatures and pressures used by U.S. refinery operators in the first half of the century.
The necessity for a gasket to have the ability to recover cannot be overstated. The effects of pressure and temperature fluctuations, the temperature differential across the flange face, together with bolt stress relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal even under these varying service conditions. The Spiral Wound Gasket is the precision engineered solution to such problems, meeting the most exacting conditions of both temperature and pressure in flanged joints and similar assemblies and against virtually every known corrosive and toxic media.The spiral wound gasket meets the most exacting conditions of both temperature and pressure in flanged joints and similar assemblies and against every known corrosive and toxic media.
ASME B16.20, which governs spiral wound gaskets, mandates the use of solid metal inner rings in:
-
Pressure Class 900 for nominal pipe sizes 24" and larger
-
Pressure Class 1500 for nominal pipe sizes 12" and larger
-
Pressure Class 2500 for nominal pipe sizes 4" and larger
-
All PTFE-filled gaskets
The standard also specifies how spiral wound gaskets should be characterized. Below you will find an illustrative image.
