Gaskets and Sheet Jointings
This gasket is certified for emission control applications.
It comprises a thin corrugated steel joint with pressed concentric grooves 6mm wide. Two adjacent grooves on either side are filled with beads of expanded-graphite Supagraf® Tape - either standard or high purity grades, depending on application.
When compressed between flanges, the metal corrugations provide a sealing capability that is enhanced by the graphite beads.
Pipelines and pressure vessels with Class 150 to 2500 flanges, or equivalent.
- Thinner than a spiral wound gasket - it can usually be fitted in place of a sheet jointing gasket in a pipe run.
- Self-locating, and often easier to install than a sheet graphite gasket.
- When supplied with tapered-slot lugs, this gasket can be used on a variety of flanges with differing bolt diameters and pitch circles.
- Metcom® Type FG316L gasket is certified as meeting TA-Luft emission control requirements.
Standard metal cores in a selection of stainless steels. Other alloys are available.
