Spiral Wound Metallic Gasket: High-Performance Sealing Solution

Spiral Wound Metallic Gasket are precision-engineered to provide reliable sealing solutions in high-pressure and high-temperature applications. These gaskets are essential for industries that require durable and resilient seals under extreme conditions, such as in piping systems, heat exchangers, vessels, and boilers. Their sophisticated construction ensures exceptional mechanical strength, corrosion resistance, and thermal stability, making them suitable for a broad range of industrial applications.

Product Construction:

• Sealing Element:
  The gasket’s sealing element is made of spirally wound V-shaped metal strips combined with a soft filler material like PTFE or expanded graphite. This construction offers flexibility, resilience, and the ability to recover and maintain a tight seal under fluctuating pressure and temperature conditions.

• Soft Filler Materials:

  • PTFE (Polytetrafluoroethylene): Ideal for use in chemical and corrosive environments due to its chemical inertness.
  • Expanded Graphite: Suitable for high-temperature applications with excellent thermal conductivity and stability.

Key Features:

1. Material Versatility:
   The gaskets are available in a variety of materials to suit different operational conditions, including high and low temperature extremes. Common materials used for the metal winding include stainless steel (SS304, SS316, SS316L, SS321, SS347) and more specialized alloys like Monel 400, Inconel, and Alloy 20.

2. High-Pressure Sealing:
   These gaskets are designed to seal high-pressure environments reliably, making them a trusted choice for demanding industrial applications where internal pressures can fluctuate significantly.

3. Thermal Cycling Resilience:
   Spiral wound gaskets maintain their sealing integrity under thermal transients and cycling conditions (when systems undergo rapid heating and cooling). This resilience minimizes leakage and ensures long-term reliability.

4. Corrosion Resistance:
   Depending on the material choice, these gaskets resist corrosion even in aggressive media environments, ensuring that the seal remains intact in applications dealing with chemical exposure or hydrocarbons.

Application Guidelines:

• High-Pressure & Vacuum Applications:
  Suitable for sealing systems that operate under high-pressure or vacuum conditions, ensuring safe and effective operation in sensitive environments.

• Piping and Flange Sealing:
  Ideal for use as flange gaskets in piping systems, ensuring a secure seal between connected pipe sections and preventing fluid or gas leaks.

• Heat Exchangers & Vessels:
  These gaskets excel in heat exchangers, boilers, reactors, and vessels, where high temperatures and pressures are common.

• OEM Equipment:
  Custom-engineered gaskets can be used in OEM (Original Equipment Manufacturer) applications, designed to meet specific equipment requirements.

• Chemical, Steam, and Hydrocarbon Industries:
  The gaskets are especially well-suited for sealing systems in the chemical, steam, and hydrocarbon industries, where high-pressure and corrosive conditions are prevalent.
