The CGI spiral wound is standard spiral wound gasket per ASME B16.20 .The Style CGI is for use with flat face and raised face flanges. This gasket features increased compressive force for blow-out prevention and is specified for high pressure/temperature service or where corrosive or toxic media are present.

In addition to an outer metal ring the CGI style gasket is fitted with an inner metal ring, constraining the sealing element on both internal and external diameters. The inner ring functions as an additional compression stop and prevents inner buckling of the Sealing element. It also creates a physical barrier between the sealing element and process stream shielding from heat and media while preventing Erosion. Style CGI gaskets are suitable for use on raised and flat faced flanged Connections and moderate to severe Service conditions.

FEATURES

• This Gasket Can be used for Raised Face Flanges & IBC flanges
• Standard sizes available for most flanges
• Inner ring plays vital role for CGI Type Gasket
• GASKET is Available with different MOC
• Metal to Soft sealing gives better Sealing

BENEFITS

• Good for Abrasive Media because of Metal Inner Rings
• Marking on Gaskets gives ease to End User.
• Gasket can be store up to 36 Months.
• A spiral wound sealing element ensures a positive seal under fluctuating temperature and pressure conditions.
• A solid metal inner ring used to protect the sealing
• Element and act as a compression stop.
• It can be supplied with pass partition bars in any
• Pass bars are secured to the inner ring and can be supplied in either solid metal or double jacketed construction.
