Metal corrugated gaskets are engineered for demanding sealing applications where standard flat or spiral wound gaskets are insufficient. Their unique corrugated structure provides spring-like elasticity, ensuring long-lasting sealing even under high pressure, extreme temperatures, or thermal cycling. Ideal for valves, pumps, flanges, heat exchangers, and critical equipment in petrochemical, power, aerospace, and cryogenic industries.
Adaptive Sealing: Corrugated metal design offers elastic spring effect, compensating flange separation caused by temperature cycles, pressure fluctuations, or vibration.
Stable Sealing Stress: Maintains effective sealing even under low bolt loads, reducing flange deformation risk and providing uniform stress distribution.
Extreme Temperature: -250°C to +1000°C (depending on material), suitable for cryogenic and high-temperature applications.
Pressure Versatility: Effective from ultra-high vacuum to pressures above 25 MPa, ideal for reactors, high-pressure heat exchangers, and turbines.
Коррозионная стойкость: Material options (304/316L stainless steel, Inconel, Hastelloy) resist acids, alkalis, solvents, and corrosive media.
Dual Sealing Mechanism: Corrugated metal provides mechanical support, while graphite or other overlay fills micro-gaps, ensuring extremely low leakage rates.
Blowout Protection: Corrugations fit tightly with flange grooves or surfaces, preventing blowout or vacuum-induced dislodgement.
Longevity & Low Maintenance: Excellent creep and relaxation resistance reduces downtime and replacement frequency, lowering total cost of ownership.
Hydrocracking, catalytic reforming reactors, heat exchangers, high-temperature high-pressure valve flanges.
Gas turbines, steam turbines, boiler feedwater pumps, and critical flange connections in nuclear power plants.
Methanol synthesis, ethylene cracking, polypropylene units, high-temperature heat-transfer and process pipelines.
LNG equipment, air separation towers, low-temperature tanks, and piping systems.
Propulsion systems, fuel systems, and test rigs under extreme operating conditions.
Non-standard sizes, special flange designs, corrugation density, number of layers, and overlay materials can all be customized.
Flexible Graphite: Enhanced sealing and high-temperature resistance, suitable for most non-oxidizing media.
PTFE: Excellent chemical inertness for corrosive media.
Ceramic Fiber: For extreme high-temperature and oxidative environments.
CNC forming ensures uniform corrugation and high geometric precision for reliable sealing.
Full inspections from raw materials to finished gaskets, including dimensional checks, hardness tests, and optional helium leak testing, ensure compliance with standards.
