ANSI B16.20 Spiral Wound Gasket Basic/Centering Ring/Inner Ring
The ANSI B16.20 Spiral Wound Metal Gasket is a highly reliable and widely used gasket in the oil and gas, chemical, and petrochemical industries. ANSI B16.20 Spiral Wound Metal Gasket is designed to provide a leak-proof seal for high-pressure and high-temperature applications.
The ANSI B16.20 Spiral Wound Metal Gasket is made up of a metallic strip and a filler material wound in a spiral pattern. The metallic strip is typically made from stainless steel, carbon steel, or other high-strength alloys, while the filler material can be graphite, PTFE, or other materials that provide good sealing performance. The spiral pattern creates a series of alternating layers of the metallic strip and filler material, forming a tight and reliable seal.
One of the key features of the ANSI B16.20 Spiral Wound Metal Gasket is its ability to handle extreme temperatures and pressures. The ANSI B16.20 Spiral Wound Metal Gasket can handle pressures up to 2500 PSI and temperatures up to 1000°F, making it an ideal choice for applications that require a high level of sealing performance.
The ANSI B16.20 Spiral Wound Metal Gasket is designed to fit into the groove of the flange, which provides a sealing surface for the gasket. The ANSI B16.20 Spiral Wound Metal Gasket is compressed by the flange bolts, causing it to deform and fill any imperfections in the flange surfaces. This creates a tight and reliable seal that can withstand high pressures and temperatures.
One of the advantages of the ANSI B16.20 Spiral Wound Metal Gasket is its ability to provide a wide range of sealing options. The ANSI B16.20 Spiral Wound Metal Gasket can be made from a variety of materials, depending on the specific application requirements. This allows the ANSI B16.20 Spiral Wound Metal Gasket to provide superior sealing performance in a wide range of operating conditions.
Another advantage of the ANSI B16.20 Spiral Wound Metal Gasket is its versatility. The ANSI B16.20 Spiral Wound Metal Gasket can be used in a variety of flange types and sizes, making it a highly adaptable sealing solution. ANSI B16.20 Spiral Wound Metal Gasket can also be used in both raised face and flat face flanges, providing a flexible and cost-effective sealing solution.
In conclusion, the ANSI B16.20 Spiral Wound Metal Gasket is a highly reliable and durable sealing solution for high-pressure and high-temperature applications. Its unique design and high-strength materials make it an ideal choice for the oil and gas, chemical, and petrochemical industries. With proper installation and maintenance, the ANSI B16.20 Spiral Wound Metal Gasket can provide a long-lasting and cost-effective sealing solution.
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.
