Spiral Wound Gasket For ASME Flanges 26 Inch Class 400 With 304 Stainless Steel And Flexible Graphite, Centering Ring For Precise Seating, Withstand High Temperature Variations And Thermal Cycling, 27.00 Inch ID 32.75 Inch OD Teadit By Sur-Seal
A spiral wound gasket is designed for sealing high-temperature, high-pressure joints on ASME B16.20 gaskets used with ASME B16.47 Series A flanges (Class 400). It features a centering ring that precisely locates the gasket on the flange face, adds radial strength, and acts as a compression limiter, while the sealing element combines 304 stainless steel windings with a flexible graphite filler to handle demanding thermal cycling in process piping.
✅ Sealing element: spiral wound with metal windings and flexible graphite filler
✅ Centering ring locates gasket on flange face and acts as a compression limiter
✅ Temperature range: -150 to 842 F (-101 to 450 C) and resistance to thermal cycling
✅ Windings: 304 stainless steel for corrosion resistance
✅ Dimensions: ID 27.00 in (685.8 mm), OD 32.75 in (832.0 mm) for 26 in piping
💡 What is a spiral wound gasket used for in ASME flange assemblies?
A handy overview:
- Seals high-pressure, high-temperature joints on ASME flanges with reliable seating
- Centering ring improves seating accuracy and helps prevent misalignment
- Withstands thermal cycling due to the graphite filler and spiral winding design
- 304 stainless steel windings resist corrosion in harsh service environments
