Graphite and Stainless Steel ASME/API/ANSI/B16.5 Spiral Wound Gasket
Graphite and Stainless Steel ASME/API/ANSI/B16.5 Spiral Wound Gasket is widely used in high-pressure and high-temperature applications in various industries. These Graphite and Stainless Steel ASME,API,ANSI,B16.5 Spiral Wound Gaskets consist of a metal winding and a filler material. Graphite and stainless steel are two commonly used materials in spiral wound gaskets. In this article, we will discuss the use of graphite and stainless steel in ASME API spiral wound gaskets.
ASME API spiral wound gaskets are designed to meet the specifications of the American Society of Mechanical Engineers (ASME) and the American Petroleum Institute (API). These gaskets are commonly used in the oil and gas industry, chemical processing plants, and power generation facilities. ASME API spiral wound gaskets can withstand high pressure and temperature conditions and are designed to provide a reliable seal.
Graphite is a commonly used filler material in ASME API spiral wound gaskets. Graphite has excellent sealing properties and is highly resistant to corrosion. Graphite-filled gaskets can withstand temperatures up to 540°C (1000°F) and pressures up to 275 bar (4000 psi). Graphite is also an excellent conductor of heat, which makes it ideal for use in high-temperature applications.
Stainless steel is a commonly used material in the metal winding of ASME API spiral wound gaskets. Stainless steel provides excellent mechanical strength and resistance to corrosion. Stainless steel grades such as 304, 304L, 316, 316L, 321, and 347 are commonly used in spiral wound gaskets. Stainless steel gaskets can withstand temperatures up to 1000°C (1832°F) and pressures up to 250 bar (3625 psi).
ASME API spiral wound gaskets can be made with various combinations of graphite and stainless steel. These gaskets can be filled with graphite and have a stainless steel winding, or they can have a graphite winding and a stainless steel inner ring. The choice of material and configuration will depend on the specific requirements of the application.
Proper installation of ASME API spiral wound gaskets is critical to ensure a reliable seal. 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, graphite and stainless steel are commonly used materials in ASME API spiral wound gaskets. Graphite provides excellent sealing properties and resistance to corrosion, while stainless steel provides mechanical strength and resistance to corrosion. ASME API spiral wound gaskets can be made with various combinations of graphite and stainless steel to meet the specific requirements of the application. Proper installation of the gaskets is critical to ensure a reliable seal.
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.
