Spiral Wound gaskets, ASME B16.20 Metal Gasket
The concept of spiral wound gasket construction was originated 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 of the gasket having the ability to recover cannot be emphasized too much. The effects of pressure and temperature fluctuations, flange surface temperature differences, and bolt stress relaxation and creep require gaskes to have sufficient flexibility and resilience to maintain sealing even under these different usage conditions. The Spiral Wound Gasket is the precision engineering solution for solving such problems, capable of meeting the strictest temperature and pressure conditions in flange joints and similar components, and resistant to almost all known corrosive and toxic media.The spiral wound gasket meets the strictest temperature and pressure conditions in flange joints and similarcomponents, and can resist every known corrosive and toxic medium.
ASME B16.20 covers spiral wound gaskets and requires the use of solid metal inner rings in the folllowing situations: Pressure Class 900, nominal pipe sizes 24 and larger, Pressure Class 1500 from nominal pipe sizes 12 and larger, Pressure Class 2500 from nominal pipe sizes 4 and larger and all PTFE filled gaskets.The characteristics of the spiral wound gaskets are also described in the same standard, and you will see its image below.
