Spiral Wound Gasket with Inner & Outer Ring – Description

A Spiral Wound Gasket (SWG) with inner and outer ring is a semi-metallic gasket designed for high-pressure and high-temperature sealing applications. It consists of a spirally wound combination of metal strip and soft filler material, along with two metallic rings that enhance performance, alignment, and safety.

This type is considered the most widely used gasket in critical industrial services, especially in oil & gas, petrochemical, and refinery sectors.

Construction / Design

The gasket is made of three main components:

1. Sealing Element (Spiral Winding)

• Alternating layers of:
  • Metal strip (SS304, SS316, Carbon Steel, etc.)
  • Filler material (Graphite, PTFE, Ceramic, Mica)

2. Inner Ring

• Located inside the winding
• Functions:
  • Prevents buckling and inward deformation
  • Protects winding from process media erosion
  • Reduces turbulence in flow

3. Outer Ring (Centering Ring)

• Located outside the winding
• Functions:
  • Ensures proper gasket alignment during installation
  • Controls compression limit (compression stop)
  • Identifies gasket size, class, and material (color coding as per ASME)

Key Features / Properties

• Suitable for high pressure & high temperature applications
• Excellent resilience and recovery
• Handles thermal cycling and pressure fluctuations
• Wide chemical compatibility (depends on filler)
• Prevents blowout and deformation
• Long service life with reliable sealing

Common Materials Metal Strip

• SS304 / SS316 / SS321
• Carbon Steel
• Alloy Steel / Inconel (for critical services)

Filler Materials

• Graphite (most common – high temperature)
• PTFE (chemical resistance)
• Ceramic / Mica (extreme heat applications)
