Stainless Steel Spiral Wound Gaskets are the industry standard with regards to sealing performance in high pressure and high temperature conditions. These gaskets are designed with spirally wound metallic ribs, usually high grade Stainless Steel 304, 316L, 321, Inconel or Mica, with special non-metallic filler such as Graphite, PTFE, or Mica.
The special spiral shape provides superior strength and a spring effect, which gives the gasket a tight fit despite changing thermal and mechanical forces. These gaskets have a load-bearing capacity and creep resistance that meet the critical safety requirements whether in pipelines or chemical reactors.

Types of Stainless Steel Spiral Wound Gaskets
1. Centering Gaskets (Outer Ring Only)
These feature a solid external metal ring that surrounds the spiral wound element. The outer ring acts as a compression stop and ensures the gasket is perfectly centered on the flange face, preventing blowouts.
2. Centering Gaskets with Inner Rings
Building on the standard design, these include an additional internal metal ring. This inner ring acts as a heat shield, prevents flange erosion, and minimizes turbulence in the fluid stream, significantly extending the service life of the connection.
3. Reinforced Gaskets
Designed for heavy-duty systems, reinforced gaskets use multiple metal plies at the inner and outer diameters without filler. This provides superior structural stability and enhanced compression characteristics for high-vibration environments.
4. Inner Ring with Reinforced Gaskets
This configuration combines a solid inner ring with reinforced outer layers. It is ideal for demanding fluid-handling applications where it reduces the accumulation of solids and minimizes erosion at the flange faces.
Applications of Stainless Steel Spiral Wound Gaskets
Stainless Steel Spiral Wound Gaskets are widely used in high-pressure and high-temperature environments, including heat exchangers, pressure vessels, chemical reactors, pipelines, offshore platforms, and petrochemical plants. Their robust construction, corrosion resistance, and precision make them suitable for industries where leak-proof sealing and long-term reliability are essential.
FAQ’s About Stainless Steel Spiral Wound Gaskets
What is the benefit of the inner ring in a spiral wound gasket?
The inner ring provides additional compression limiting, prevents the gasket from “buckling” inward, and protects the sealing element from direct exposure to the process media.
Can these gaskets be used with both 304 and 316L flanges?
Yes, we manufacture SS Spiral wound Gaskets in matching grades (304, 316L, 321, etc.) to ensure chemical compatibility and prevent galvanic corrosion.
What filler material should I choose?
Graphite is excellent for high temperatures (up to 550°C), while PTFE is the preferred choice for extreme chemical resistance in lower temperature ranges (up to 260°C).
