PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket

PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket

The ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket is a type of gasket designed to meet the requirements of the ASME B16.20 standard for metallic gaskets for pipe flanges.

This The ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket consists of a metallic winding strip, which is spirally wound and sandwiched between layers of non-metallic filler material, such as graphite. The winding strip is coated with PTFE, which provides excellent chemical resistance and makes it easier to remove the ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket from the flange after use. The use of PTFE also reduces the friction between the ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket and the flange, which helps to prevent damage to the flange surface.

The ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket,the winding strip is made of carbon steel and is coated with a layer of PTFE to improve its resistance to chemicals and reduce friction. The centering ring is made of carbon steel and is coated with a layer of stainless steel 304, which provides additional strength and resistance to corrosion. The inner ring is made of stainless steel 304 and provides additional support to the winding strip.

The ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket,the filler material is made of graphite, which is known for its excellent sealing properties and resistance to high temperatures. The graphite filler material is wrapped around the winding strip and sandwiched between the centering and inner rings to create a tight seal.

This ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket is commonly used in high-temperature and high-pressure applications, such as those found in the chemical and petrochemical industries. The ASME B16.20 PTFE Coated CS Outer Ring SS304 Inner Ring Graphite Filler Gasket provides a reliable and durable seal that can withstand the harsh conditions found in these environments. The PTFE coating and graphite filler material help to ensure a tight seal, even when exposed to high 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 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.
