STYLE CG-RJ & CGI-RJ SPIRAL-WOUND GASKETS
FOR USE IN ASME B16.5 AND API 6A RING-JOINT FLANGES
CG-RJ and CGI-RJ spiral wound gaskets are designed
for use, as a replacement maintenance item, of standard
oval and octagonal ring joint gaskets.
These gaskets are available for NPS 1/2 to 24
and pressure classes 150 to 1500.
Gasket thickness is 0.175" ( 4.5mm) and the
outer ring thickness is 0.125" (3.2mm).
Style CGI-RJ gaskets are fitted with an inner ring
O.125 (3.2mm) thick.
Flexitallic recommends CGI-RJ gaskets for pressure
classes 900 and above, and where operating
temperatures are above 572 F (300 C).
Consult our technical department for CGI-RJ gasket
dimensions.
Note:
Clearance dimensions between flange faces should be checked on close coupling pipework prior to installation
of CG-RJ and CGI-RJ gaskets to ensure that optimum compression can be achieved without over stressing bolts and
or flanges.
It is the user’s responsibility to ensure that there is sufficient clearance between the flange bore and ring groove for proper
seating of the gasket.
Dimensions are listed below for CG-RJ spiral wound gaskets. Flexitallic’s technical department should be consulted for
CGI-RJ and API gasket sizes.
