Audited Supplier ANSI B16.20 SS Inner Ring Spiral Wound Gasket for B16.5/B16.47 Flange
ANSI B16.20 SS inner ring spiral wound gaskets are a type of gasket commonly used in high-pressure and high-temperature applications. These gaskets are designed to provide a reliable seal between flange connections in piping systems.
The ANSI B16.20 standard specifies the dimensions, tolerances, and materials for spiral wound gaskets used in flanged connections in piping systems. The standard applies to gaskets with nominal diameters from 15 mm to 3,000 mm and pressures up to Class 2500.
The SS inner ring in these gaskets provides additional structural support to the gasket, preventing it from collapsing under high pressure. The inner ring is typically made of stainless steel, which provides excellent corrosion resistance and can withstand high temperatures. The inner ring also helps to distribute the bolt load evenly across the flange face, ensuring a secure and reliable seal.
The spiral wound construction of the gasket consists of a metal winding and a filler material. The metal winding is typically made of stainless steel or other metals, providing the necessary strength and resilience to withstand high pressure and maintain the integrity of the gasket. The filler material is typically made of graphite, PTFE, or other materials, providing excellent sealing properties.
The combination of the SS inner ring and the spiral wound construction of the gasket results in a highly effective sealing solution for high-pressure and high-temperature applications. These gaskets are commonly used in the oil and gas, chemical, and petrochemical industries, where reliable and long-lasting seals are essential.
In conclusion, ANSI B16.20 SS inner ring spiral wound gaskets are a highly effective sealing solution for high-pressure and high-temperature applications. The SS inner ring provides additional structural support to the gasket, while the spiral wound construction provides excellent sealing properties. These gaskets are widely used in the oil and gas, chemical, and petrochemical industries, providing a reliable and long-lasting seal in even the most demanding applications.
Basic Type
Basic construction type, inner and outer diameters are reinforced with several piles of metal without filler to give greater stability and better compression characteristics. - Suitable for tongue and groove, male and female or grooved to flat face flange assemblies.
Inner Ring Type
Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion, damages of gasket between flange bore and the inside diameter, the annular space is filled up by solid inner metal ring. - Suitable for male and female pipe flanges.
Outer Ring TypeSolid outer ring accurately locates the gasket on the flange face to give the additional radial strength to prevent the gasket blowout and acts as a compression limiter. In case of installing the outer ring, it is very easy to install the gasket to flange face because the end of outer ring will touch at bolts - Suitable for use with flat face and raised face flanges. For class 900 and above an internal ring is recommended.
Inner & Outer Rings TypeA inner ring and outer ring type gasket will give an additional compression limiting stopper for gasket inner and outer side. It will prevent the corrosions on flange face at annular space. - Suitable for use with flat face and raised face flanges and specified for high pressure / temperature service - Class 900 and above or where corrosive or toxic media are present.
Typical Applications
Pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. Petrochemical, chemical, mechanical manufacturer, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear power station and navigation, etc.
