SS304/304L/316/316L/321/347 Inner Ring Graphite Filler Spiral Wound Gasket
SS304/304L/316/316L/321/347 Inner Ring Graphite Filler Spiral Wound Gasket is a popular choice for high-pressure and high-temperature applications in various industries. SS304,304L,316,316L,321,347 Inner Ring Graphite Filler Spiral Wound Gasketts consist of a metal winding and a filler material. Stainless steel is a commonly used metal winding material, and the filler material is often graphite. In this article, we will discuss the use of spiral wound gaskets made of SS304/304L, SS316/316L, SS321, and SS347, filled with graphite.
SS304/304L stainless steel spiral wound gaskets are commonly used in industries such as food processing, pharmaceutical, and biotech. These gaskets are designed to withstand low to moderate pressure and temperature conditions. The gaskets are typically filled with graphite, which provides excellent sealing properties at high temperatures and pressures.
SS316/316L stainless steel spiral wound gaskets are widely used in industries such as chemical processing, oil and gas, and power generation. These gaskets are designed to withstand high pressure and temperature conditions. The gaskets can be filled with graphite, which provides excellent sealing properties and resistance to corrosion.
SS321 and SS347 stainless steel spiral wound gaskets are commonly used in high-temperature applications where the process fluid contains high levels of sulfur or other corrosive materials. These gaskets are designed to withstand high pressure and temperature conditions. The gaskets are typically filled with graphite, which provides excellent sealing properties and resistance to corrosion.
Graphite-filled spiral wound gaskets are ideal for use in high-temperature and high-pressure applications. Graphite is a naturally occurring mineral that is highly resistant to corrosion and can withstand high temperatures and pressures. Graphite-filled gaskets can be used in a wide range of applications, including chemical processing plants, power generation facilities, and oil and gas refineries.
Proper installation of spiral wound gaskets is critical to ensuring the safety and reliability of the piping system. The gasket must be compressed evenly to achieve an effective seal. Over-compression can damage the gasket, while under-compression can result in leaks. It is also important to select the appropriate gasket size and thickness for the application.
In conclusion, SS304/304L, SS316/316L, SS321, and SS347 are commonly used materials in spiral wound gaskets, and graphite is a common filler material. Spiral wound gaskets filled with graphite are ideal for high-temperature and high-pressure applications in various industries. Proper selection and installation of the gaskets are critical to ensuring the safety and reliability of the piping system.
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 Type
Solid 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 Type
A 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.
