For improving sealing performance on double jacketed gaskets, graphite adhesive tape is usually applied on both faces of the gasket.
During this application, the tape needs to be bent to follow gasket circumference; this manual bending deformation becomes even more difficult time by time when the gasket sealing surface width increases and gasket diameter decreases.
VED complies with standard ASME PCC-1 ed. 2019 [P-4.5.1]
“Field application of graphite tape to conventional double-jacketed gaskets is not recommended and is not as effective as purchasing a gasket with graphite facings specified as part of the inherent gasket design”, and for that reason VED supplies a new solution, allowing at the same time a field application and a final result like a purchased gasket:
GRAFACE, the circumference shaped adhesive tape along gasket diameter, avoiding manual deformation during the application.
By using GRAFACE the deformation, to be applied on the adhesive tape, will be ten times less allowing a more regular gasket cover, without ripples and/or creases.
This particular shaped adhesive tape is supplied in various widths according to specific gasket diameters.
It is important to remember: do not use a tape width exceeding the gasket one, and to follow indications, inside the box, on how to cut the tape in making junctions.
