The DH-G-MG Metallic Kammprofile Gasket is a high-performance metal gasket featuring a corrugated (kammprofile) metal core and graphite/PTFE facing. Constructed from 316L stainless steel (standard) or Inconel 625 (high-temperature), it meets ASME B16.20, API 601, and ISO 22262-1 standards. Standard sizes cover DN15-DN2000 flanges (PN16-PN420), with custom profiles available for non-standard flanges; thickness ranges from 1.5mm-5.0mm (core + facing).
Temperature Range: 316L variant: -196℃ to +450℃; Inconel 625 variant: -200℃ to +650℃.
Pressure Capacity: Up to 45MPa (static), 30MPa (dynamic) – suitable for high-pressure vessel flanges.
Sealing Performance: Helium leak rate ≤ 1×10⁻⁹ Pa·m³/s (ISO 12747-2); effective on flange roughness up to Ra 1.6μm.
Facing Options:
Graphite facing: For high temp (up to 450℃), thermal conductivity 10 W/(m·K).
PTFE facing: For chemical resistance (acids, solvents), operating temp up to 260℃.
Structural Integrity: Corrugated profile provides 30% higher compression rebound than flat metal gaskets.
Oil & Gas: Wellhead flanges (40MPa), subsea pipeline connections (30MPa, -50℃).
Power Generation: Steam turbine flanges (450℃, 25MPa), nuclear auxiliary system valves.
Chemical Processing: High-pressure reactor flanges (35MPa, 300℃), autoclave doors.
Petrochemical: Hydrocracker flanges (400℃, 35MPa), amine treater vessels.
Graphite facing: Choose for temperatures > 260℃, thermal cycling applications, or when thermal conductivity is critical (e.g., steam lines).
PTFE facing: Choose for chemical service (acids, solvents), food/pharma applications (FDA-compliant), or to prevent flange adhesion.
Hybrid facing: Available for mixed service (e.g., 300℃ + chemical exposure).
Works with all standard flange types:
Raised face (RF): Optimal for PN16-PN100.
Ring type joint (RTJ): Use with Inconel core for PN160-PN420.
Flat face (FF): Requires PTFE facing and lower compression (10-15%).
Ensure flange hardness < core hardness (316L core: 180 HV; Inconel 625: 220 HV).
