Graphite Filler Spiral Wound Gaskets with Stainless Steel Ring
Graphite spiral wound gaskets are a type of gasket that is widely used in industrial applications to create a seal between two or more surfaces. These gaskets are typically made of a combination of graphite and metal, and they are designed to withstand high temperatures, high pressures, and corrosive environments.
The spiral wound gasket consists of a metal strip that is wound spirally around a graphite filler material. The metal strip provides structural support and prevents the gasket from collapsing under pressure, while the graphite filler material provides excellent sealing properties. The winding of the metal strip around the graphite filler creates a v-shaped profile, which allows the gasket to compress and create a tight seal.
One of the advantages of graphite spiral wound gaskets is their ability to maintain a seal even under extreme conditions. These gaskets can withstand temperatures ranging from -200°C to 550°C, pressures up to 2500 PSI, and highly corrosive environments. This makes them an ideal choice for use in applications where other gaskets would fail, such as in chemical processing plants, oil and gas refineries, and power generation facilities.
Graphite spiral wound gaskets are also highly resistant to a wide range of chemicals, including acids, alkalis, and organic solvents. This makes them a versatile choice for use in a variety of industrial applications. Additionally, they have excellent thermal conductivity, which allows them to dissipate heat quickly and evenly, preventing hot spots and minimizing the risk of damage to the gasket.
Another advantage of graphite spiral wound gaskets is their ability to conform to irregular surfaces. The v-shaped profile of the gasket allows it to compress and fill gaps and voids between the surfaces it is sealing. This ensures a tight and reliable seal, even in applications where the surfaces are not perfectly flat or parallel.
In conclusion, graphite spiral wound gaskets are a highly effective sealing solution for a wide range of industrial applications. They offer excellent resistance to high temperatures, high pressures, and corrosive environments, making them an ideal choice for use in harsh industrial environments. Their ability to conform to irregular surfaces and their resistance to a wide range of chemicals make them a versatile choice for use in a variety of 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.
