CGG® Gasket
Description
The CGG® is a corrugated gasket with APX2 graphite facings, originally developed by Chevron for use in heat exchangers and fixed equipment. Based on exhaustive field and laboratory research, each parameter of the CGG® is finely tuned to optimize its performance and reliability in the demanding environment of heat exchangers.
Application
This gasket is for use in heat exchanger girth flanges where the width of the gasket is ½” or wider. When properly installed in code-designed flanges, the CGG gasket is suitable for service pressures to 3,000 psi. It has been successfully used in tens of thousands of heat exchangers worldwide, resulting in leak-free sealing from turnaround to turnaround.
Sealing Characteristics
- Turnaround to turnaround reliability. When properly installed, the CGG® gasket resists damage from radial shear forces, allowing it to remain tight throughout the entire service cycle.
- Replaces multiple styles of gaskets.
- Constructed of fire-safe materials.
- APX2 flexible graphite facings have extremely low oxidation rates at elevated temperatures, making the CGG® gasket suitable for services up to 1,000°F.
Chemical Compatibility
Subject to materials, CGG® gaskets can be used in a wide variety of media, with a pH range varying from 0-14.
Application/Compatibility Guide is available upon request.
Available Options
Standard core materials are available in 304 or 316 stainless steel. Other alloys available upon request. The CGG® gasket is supplied in a standard thickness of 1⁄16″. Custom configurations are also available, including double-rail and full-face designs.
Approvals & Certificates
APX2 graphite facing, as well as a metal corrugated core, are recognized as fire-rated materials. For additional information, please consult with the Engineering team.
