Classification of Metal Gaskets
1. Solid Metal Gaskets: Power of Single-Piece Metal
Crafted from a single, robust metal piece chosen for its resilience to temperature and pressure, solid metal gaskets excel in high-pressure and high-temperature applications, boasting enduring durability and shape retention.
2. Ring Joint Gaskets (RTJ): Symphony of Engineering Excellence
Precision-engineered for high-pressure sealing, RTJ gaskets find prominent usage in the oil and gas industry and the petrochemical sector, specifically in high-pressure pipeline systems and wellhead equipment.
3. Spiral Wound Gaskets (SWG): Resilience of Spiral Innovation
Comprising a spirally wound metal strip with a filler material, SWG offers resilience and compressibility, making them ideal for sealing high-temperature, high-pressure flange connections in power plants and chemical processing facilities.
4. Semi-Metallic Gaskets: Defying Extremes in Aggressive Environments
Blending metallic and non-metallic materials, semi-metallic gaskets cater to diverse applications, including high temperatures, pressures, and aggressive media.
5. Metal Jacketed Gaskets: Armored Guardians of Critical Equipment
Featuring a compressible filler material enclosed in a thin metal jacket, metal jacketed gaskets are prevalent in the petrochemical and refining industries, sealing heat exchanger connections, flanges, and critical equipment.
6. Kammprofile Gaskets: Mastering Challenges with Serrated Excellence
With a serrated metal core and compressible sealing material, Kammprofile gaskets excel in challenging applications with high temperatures and pressures, commonly used in refineries and chemical plants.
7. Composite Metal Gaskets: Fusion of Metals for Superior Strength
Bonded from different metals, composite metal gaskets offer a synergy of materials, providing enhanced strength, temperature resistance, and corrosion resistance.
