LEADING METAL GASKETS MANUFACTURER, EXPORTER & SUPPLIER
Manufacturer, Exporter & Supplier of Copper-Nickel, Stainless Steel & Alloy Industrial Gaskets
Multiple Sealing Lines for Pressure Vessels, Heat Exchangers & Low-Bolt-Load Flanges
Corrugated Metal gaskets are manufactured by forming a thin metal sheet into a series of concentric corrugations — creating multiple raised contact ridges across the gasket face. When compressed under bolt load, these ridges bite into the flange surface and deform slightly, creating multiple independent sealing lines that significantly enhance leak tightness compared to a flat gasket of the same material.
Corrugated metal gaskets can be supplied plain or with a soft overlay layer — typically flexible graphite or PTFE — which further enhances conformability and surface fill for improved sealing performance, in any of our seven manufactured alloys.
Available Materials: Copper-Nickel · Stainless Steel · Copper · Brass · Inconel · Monel · Hastelloy
Sunflex Metalloy manufactures Corrugated Metal Gaskets in seven premium alloys, so you can match the gasket material precisely to your process fluid, temperature, and corrosion requirements.
Copper-Nickel (Cu-Ni 90/10 / 70/30) is one of the most requested materials for corrugated metal gaskets, offering outstanding seawater & biofouling resistance, with a maximum operating temperature of 400°C and a typical pressure rating of Class 150–2500 — making it the benchmark choice for marine, offshore & desalination duty.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
Stainless Steel (SS 304 / 316 / 316L) is one of the most requested materials for corrugated metal gaskets, offering excellent general & chemical corrosion resistance, with a maximum operating temperature of 600°C and a typical pressure rating of Class 150–2500 — making it the most versatile, cost-effective all-round choice.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
Copper (C11000 / ETP) is one of the most requested materials for corrugated metal gaskets, offering good ductility & soft-sealing conformability, with a maximum operating temperature of 250°C and a typical pressure rating of Class 150–1500 — making it low-to-medium pressure sealing with excellent conductivity.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
Brass (CZ108 / C36000) is one of the most requested materials for corrugated metal gaskets, offering moderate corrosion resistance, good machinability, with a maximum operating temperature of 200°C and a typical pressure rating of Class 150–900 — making it economical general-duty & instrumentation sealing.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
Inconel (600 / 625 / 718) is one of the most requested materials for corrugated metal gaskets, offering exceptional oxidation & high-temperature resistance, with a maximum operating temperature of 1000°C+ and a typical pressure rating of Class 150–2500 — making it extreme heat, cryogenic & superalloy-grade service.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
Monel (400 / K-500) is one of the most requested materials for corrugated metal gaskets, offering outstanding resistance to acids & seawater, with a maximum operating temperature of 480°C and a typical pressure rating of Class 150–2500 — making it hydrofluoric acid & chemical processing duty.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
Hastelloy (C276 / C22) is one of the most requested materials for corrugated metal gaskets, offering extreme resistance to highly corrosive/oxidizing media, with a maximum operating temperature of 1000°C+ and a typical pressure rating of Class 150–2500 — making it the premium choice for the harshest chemical environments.
Best For: Marine heat exchangers · Pressure vessels · Glass-lined or fragile equipment flanges · Process columns · Low bolt load flange connections
