Flexible Graphite Filler Metal Spiral Wound Gasket with Green/Yellow Epoxy Coating
A Flexible Graphite Filler Metal Spiral Wound Gasket is a type of gasket that combines the strength and durability of a metal spiral wound gasket with the flexibility and chemical resistance of graphite. Flexible Graphite Filler Metal Spiral Wound Gasket is commonly used in high-temperature and high-pressure applications where a reliable seal is essential.
The Flexible Graphite Filler Metal Spiral Wound Gasket is made by spirally winding a thin strip of metal, typically stainless steel, around a center filler material made from flexible graphite. The metal strip provides strength and stability, while the graphite filler material provides flexibility and chemical resistance. The result is a gasket that is both durable and able to withstand a wide range of chemicals and fluids.
One of the key benefits of the flexible graphite filler metal spiral wound gasket is its ability to create a seal that is virtually leak-proof. This is achieved by the design of the gasket, which allows it to conform to the irregularities of the flange surfaces, creating a tight and secure seal. The flexible graphite filler material also ensures that the gasket remains flexible, making it easy to install and remove when necessary.
Another advantage of the flexible graphite filler metal spiral wound gasket is its ability to withstand high temperatures and pressures. This makes it ideal for use in applications such as petrochemical processing, where extreme conditions are common. The gasket is also resistant to most chemicals, ensuring that it remains functional even in harsh environments.
Installation of the flexible graphite filler metal spiral wound gasket requires special attention to ensure that it is installed correctly. The flange surfaces must be clean and free of any debris or contaminants that could compromise the seal. Additionally, proper torque values must be applied to the bolts to ensure that the gasket is compressed evenly.
In conclusion, the Flexible Graphite Filler Metal Spiral Wound Gasket is a reliable and durable sealing solution that is widely used in high-temperature and high-pressure applications. Its ability to withstand extreme conditions, resistance to chemicals, and flexibility make it a popular choice among engineers and technicians in the petrochemical industry.
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.
