Audited Supplier ASME B16.20 Spiral Wound Gasket with Carbon/Stainless Steel Outer Ring
ASME B16.20 316L Spiral Wound Gasket,ASME B16.20 is a standard for spiral wound gaskets used in process piping and equipment in various industries such as chemical, petrochemical, and power generation. ASME B16.20 316L Spiral Wound Gasket is widely used for their excellent sealing performance in high-pressure, high-temperature, and corrosive environments. The ASME B16.20 standard specifies the requirements for the design, materials, dimensions, and marking of spiral wound gaskets.
316L stainless steel is a commonly used material for ASME B16.20 316L Spiral Wound Gasket in the chemical and petrochemical industries. It has excellent corrosion resistance, high temperature resistance, and good mechanical properties. 316L stainless steel spiral wound gasket is often used for sealing applications in aggressive media, such as acids, alkalis, and halogens.
The ASME B16.20 316L Spiral Wound Gasket consists of a metallic winding strip and a non-metallic filler material. The metallic strip is usually made of stainless steel, while the filler material can be made of graphite, PTFE, or other materials. The winding strip is wound spirally with the filler material in between the layers. The winding strip and the filler material are selected based on the application requirements such as temperature, pressure, and chemical compatibility.
The ASME B16.20 standard specifies the dimensions of spiral wound gaskets for different flange sizes and pressure classes. The standard also defines the tolerances for the dimensions of the ASME B16.20 316L Spiral Wound Gasket. The dimensions of the ASME B16.20 316L Spiral Wound Gasket is critical for ensuring proper sealing performance. The standard also specifies the marking requirements for the ASME B16.20 316L Spiral Wound Gasket, which include the manufacturer's name, material type, and size.
The design of spiral wound gaskets is critical for their sealing performance. The design should ensure that the gasket conforms to the flange surface and the bolts' load is evenly distributed. The design should also prevent the winding strip from buckling or over-compressing, which can lead to leakage. The design should consider the minimum and maximum seating stress requirements for the ASME B16.20 316L Spiral Wound Gasket to achieve a tight seal.
The manufacturing process of spiral wound gaskets involves winding the metallic strip and the filler material into a spiral shape. The winding process should ensure that the winding strip is evenly wound and that the filler material is evenly distributed between the layers. The manufacturing process should also ensure that the ASME B16.20 316L Spiral Wound Gasket is dimensions and tolerances are within the specified limits.
The installation of spiral wound gaskets is critical for their sealing performance. The ASME B16.20 316L Spiral Wound Gasket should be installed with the proper compression load to ensure that it conforms to the flange surface and provides a tight seal. The installation should also ensure that the bolts are evenly torqued to distribute the load evenly across the ASME B16.20 316L Spiral Wound Gasket.
In conclusion, ASME B16.20 316L Spiral Wound Gasket is widely used in process piping and equipment for their excellent sealing performance in high-pressure, high-temperature, and corrosive environments. The ASME B16.20 316L Spiral Wound Gasket is design, materials, dimensions, and marking are specified in the standard to ensure their proper performance. The manufacturing process and installation of the ASME B16.20 316L Spiral Wound Gaskets are critical for their sealing performance, and they should be carried out with proper care and attention to detail.
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.
