Our grooved metal, Kammprofile-type gaskets comprise a metal core with concentric grooves on either side. They usually have a soft layer of sealing material bonded to both grooved faces.
Flanges of high temperature/pressure pipework and vessels where operating conditions can fluctuate. They are also recommended for heat exhangers.
•Suits vast ranges of operating conditions.
•Line temperatures and pressures up to 650°C or 25MPa/250bar.
•Undamaged cores can often be fitted with new soft faces to reduce maintenance costs.
•Metakamm® gaskets with facings of graphite or PTFE are certified as meeting TA-Luft emission control requirements.
•Products are manufactured in accordance with all relevant gasket standards to suit flange designations: ASME B16.5, BS1560 (only part 3.2 is still current), ASME B16.47 Series A (MSS-SP44), ASME B16.47 Series B (supersedes API605), BS EN 1092 (supersedes BS4504), DIN, JIS and NF.
