Classification:

  • Type: Metallic Gaskets
  • Application: Used in applications where high temperature and high-pressure resistance is required, such as in pipelines, pressure vessels, heat exchangers, and flanged connections. Common in industries like oil & gas, chemical processing, petrochemical, power generation, and marine applications.
  • Materials: Carbon Steel, Stainless Steel (SS304, SS316), Inconel, Monel, Copper, etc.
  • Pressure Rating: Typically rated for Class 150, Class 300, Class 600, Class 900, Class 2500, or even higher for extreme pressure applications.
  • Temperature Range: Ranges from -200°C to +1000°C, depending on the specific material and type of gasket.

Description:

Metallic Gaskets are engineered for high-pressure, high-temperature applications where traditional soft gaskets (like rubber or elastomeric) might fail. These gaskets are designed to provide a reliable, leak-proof seal between mating flanges and other pipe fittings under demanding conditions.

Types of Metallic Gaskets:

  • Ring Type Joint (RTJ) Gaskets: These gaskets are typically used in high-pressure and high-temperature environments, such as oil and gas pipeline systems. The gasket is made from metal and shaped in a ring form that fits into a groove in the flange. It provides excellent sealing under high pressure.
  • Spiral Wound Gaskets: These consist of a combination of metal and filler material wound in a spiral pattern. They offer flexibility and compressibility while maintaining a reliable seal. These gaskets are widely used in heat exchangers and pressure vessels.
  • Kammprofile Gaskets: A metal core gasket with an elastomeric sealing layer or metal sealing facing, providing a tight seal in high-pressure applications. The Kammprofile gasket offers high mechanical strength and excellent sealing properties.
  • Solid Metal Gaskets: These are made from a single piece of metal, usually stainless steel, and are used in applications where extremely high temperatures and pressures are encountered.
  • Metal Jacketed Gaskets: A combination of metal and non-metallic materials (like graphite or asbestos), where the metal provides structural strength and the non-metallic material acts as the sealing material.

Applications:

  • Oil & Gas: Used in pipelines, pressure vessels, and flanged connections in both offshore and onshore systems.
  • Chemical Processing: Metal gaskets are used in reactors, distillation columns, and piping where high temperatures or pressures are involved.
  • Power Generation: Found in steam and gas turbines, heat exchangers, and boilers where they seal critical components.
  • Marine & Aerospace: Used in exhaust systems, engines, and turbines where high-temperature resistance is crucial.
  • Food & Beverage Industry: Metal gaskets are sometimes used in high-temperature food processing equipment.

Advantages:

  • High Pressure and Temperature Resistance: Metallic gaskets are designed to handle extreme conditions that would damage other types of gaskets.
  • Durability: Long-lasting, even under aggressive operating conditions such as high pressures, temperatures, and chemical exposures.
  • Leak-Proof: Provides excellent sealing even in critical applications, preventing hazardous leaks in pressurized systems.
  • Versatile: Can be used in a wide range of industrial applications, including gas, steam, and chemical handling systems.
