Metallic and Semi-Metallic Gaskets

Metallic and semi-metallic gaskets are crucial for industrial applications where high pressures and high temperatures are commonly found. Metallic and Semi-Metallic gaskets are those trusted in the most critical and rigorous sealing environments including, aircraft, aerospace, oil and gas production, and hazardous chemical processing. 

Metallic and Semi-Metallic Gaskets Include:

• Ring Type Joint (RTJ) Gaskets: Common in oil and gas, petrochemical, and energy industries, they utilize a wedging action to create a high-integrity seal in high-pressure/high-temperature conditions.

• Corrugated Metal Gaskets: Feature corrugated metal faced with a soft material like flexible graphite or PTFE, providing conformability and recovery.

• Kammprofile Gaskets: Have a solid metal core with machined serrations and a soft facing material (flexible graphite, mica, or PTFE), providing durability and sealing at high temperatures and pressures.

• Metal Jacketed Gaskets: A soft filler material is partially or wholly encased in a metal jacket, with the inner metal overlap acting as the primary seal.

• Spiral Wound Gaskets (SWG): Comprise alternating layers of metal strips and filler material (typically flexible graphite or PTFE) wound together. They offer resilience and a robust seal even under fluctuating conditions. Often include inner and/or outer rings for better sealing and stability.

   

Selecting the appropriate metallic or semi-metallic gasket depends on the specific operating conditions, including temperature, pressure, the media being sealed, and the mechanical characteristics of the joint. Consult with our experts to ensure you choose the right gasket for your application. We’ll guide you through the selection process, referencing manufacturer data sheets to guarantee optimal performance and safety.
