Metallic Flange B16.5 RF ASME B16.20 Spiral Wound Gasket for Pump
Metallic flange B16.5 ASME B16.20 spiral wound gaskets are a specialized type of gasket designed to provide a reliable and long-lasting seal in high-pressure and high-temperature applications. These gaskets are constructed from a range of metallic materials, including stainless steel, carbon steel, and various high-temperature alloys.
The metallic flange B16.5 ASME B16.20 spiral wound gasket is designed with a spiral wound metal core, which is wrapped with alternating layers of metal and a compressible filler material, typically flexible graphite. The metal layers provide strength and resilience, while the filler material provides a uniform and flexible seal. The gasket is designed to fit standard ASME B16.5 flanges, and is manufactured to strict dimensional and material specifications.
One of the key advantages of metallic flange B16.5 ASME B16.20 spiral wound gaskets is their ability to withstand high levels of pressure and temperature. The spiral wound metal core and compressible filler material provide strength and resilience, allowing the gasket to maintain its shape and seal even under extreme conditions. The metallic construction of these gaskets also makes them highly resistant to corrosion and chemical attack, making them an ideal choice for harsh or aggressive environments.
Another advantage of metallic flange B16.5 ASME B16.20 spiral wound gaskets is their flexibility and adaptability. The gasket is designed to conform to the flange surfaces, providing a tight and uniform seal that is resistant to leaks. The metal layers provide a degree of elasticity, allowing the gasket to adapt to changes in flange loading and temperature fluctuations. This helps to prevent leaks and maintain system integrity over the long term.
Metallic flange B16.5 ASME B16.20 spiral wound gaskets are also designed to be easy to install and remove. The gasket can be cut to size using standard tools, and can be installed quickly and easily. These gaskets are also easy to remove, and do not leave behind any residue or damage to the sealing surfaces.
In conclusion, metallic flange B16.5 ASME B16.20 spiral wound gaskets are an excellent choice for high-pressure and high-temperature applications where a reliable and long-lasting seal is required. With their ability to withstand extreme conditions, adapt to changes in flange loading, and easy installation and removal, metallic flange B16.5 ASME B16.20 spiral wound gaskets provide a dependable sealing solution that can help to prevent leaks and maintain system integrity.
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.
