Metallic Gasket for Flange/Valve/Pump/Boiler
Metallic gaskets are commonly used in high-pressure and high-temperature applications, such as flanges, valves, pumps, and boilers for pipes. These gaskets are made of metal, such as stainless steel, copper, or other alloys, and are designed to provide a seal between two metal surfaces.
When selecting a metallic gasket, it is important to consider the operating conditions, such as temperature, pressure, and fluid compatibility. The gasket should be able to withstand the operating conditions without deforming or failing.
There are several types of metallic gaskets available, including:
Spiral wound gaskets: These gaskets consist of a metal winding and filler material. They are suitable for high-temperature and high-pressure applications.
Ring joint gaskets: These gaskets are designed for high-pressure applications and are commonly used in flanges. They are made of metal and have a trapezoidal cross-section.
Camprofile gaskets: These gaskets consist of a metal core with a profiled surface and a soft filler material. They are commonly used in flanges and valves.
Metal jacketed gaskets: These gaskets consist of a metal jacket with a soft filler material. They are suitable for applications where a high degree of compression is required.
Solid metal gaskets: These gaskets are made of a single piece of metal and are suitable for high-temperature and high-pressure applications.
In summary, metallic gaskets are an important component in high-pressure and high-temperature applications such as flanges, valves, pumps, and boilers for pipes. When selecting a metallic gasket, it is important to consider the operating conditions and select the appropriate type of gasket for the application.
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.
