Applicable Standards	ASME B16.20, BS, JIS, DIN, Suited for ASME B16.47 series A/B flanges
Hoop material	ss304, ss316L, 321, 317(L), Monel,Ti, Ni, INC, C/B Zr702, Etc.
Filler	Graphite, PTFE, Non-asbestos, Mics, Monel, etc.
Inner & outer ring material	CS, ss304, ss316L, 321, 317(L), Monel,Ti, Ni, INC, Hast.C/B Zr702,Etc.
Metallic Strip	The standard thickness of the metallic strip is 0.2 mm.
Filler	Filler is normally used for thickness from  0.5 mm to 0.6 mm.
Centering ring	The centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plated or painted to avoid corrosion. Other materials are available on request.
Inner ring	Inner ring is used to avoid excessive compression due to high seating stress in high-pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic srtip.

   

Gasket Selection
Style CG - Utilizes an external ring which accurately centers gasket on flange face, provides additional radial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges up to and inclusive of class 2500. See note at bottom of page 8 for inner ring requirements.	Style CGI - A Style CG gasket fitted with internal ring which gives an additional compression limiting stop and provides heat and corrosion barrier protecting gasket windings and preventing flange erosion. Suitable for use with flat face and raised face flanges. See note at bottom of page 8 for inner ring requirements.	Style R - Basic construction type. Inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression and sealing characteristics. Suitable for tongue and groove or male and female or grooved to flat face flange assemblies.	Style RIR - Solid inner metal ring acts as a compression stop and fills the annular space between flange bore and the inside diameter of the gasket. Designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimize erosion at flange faces. Suitable for male and female pipe flanges
