Spiral Wound gaskets, ASME B16.20 Metal Gasket
SS304/SS316 spiral wound gaskets are a type of industrial gasket commonly used in food and beverage processing applications.
The gasket consists of a spiral wound sealing element made of alternating layers of metal and soft filler material. The metal layers are typically made of stainless steel (SS304 or SS316), which provides excellent resistance to corrosion, while the soft filler material provides a reliable seal against the flanges.
In food and beverage processing applications, SS304/SS316 spiral wound gaskets are used to provide a reliable seal in piping systems that transport food products, beverages, and other materials. The gasket is designed to withstand exposure to harsh environmental conditions, including high pressures, temperatures, and corrosive chemicals.
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.
The stainless steel material used in the gasket provides excellent strength and durability, making it suitable for use in high-stress applications. It is also resistant to corrosion, which makes it ideal for use in food and beverage processing applications, where hygiene and safety are critical.
SS304/SS316 spiral wound gaskets are a reliable and durable sealing solution for food and beverage processing applications, providing a tight and reliable seal while meeting the required safety and performance standards. Their stainless steel construction and spiral wound design make them suitable for use in a wide range of industrial applications, helping to ensure the safety and efficiency of food and beverage processing systems.
