Spiral Wound Gasket - Stainless Steel 304, 0.006" Thickness | High-pressure Flexibility, Fire Safe, Resistant To Extreme Temperatures

Components:

• Metallic strip - holds the filler
• Filler - flows under pressure filling the imperfections and creating sealability for the gasket.
• Guide ring-holds the filler and metallic strip in the proper position.

Materials used:

• Metallic strip - 0.006" thick, Stainless Steel 304, 304L, 316, and 316L. 'L' specifies low carbon content. Other materials are available upon request.
• Filler types -

  • Flexible graphite - temperature depending on applications:
    • Steam and hydrocarbons - 1200 F.
    • Oxygen service(if sealing element is totally enclosed) 930F
    • Oxidizing services - +600 F
    • Gasket must be enclosed.
    • Oxidizing agents are nitric acid and sulfuric acids, chromium, chlorine acids and liquid alkaline metals.
    • Fire safe.
  • PTFE - higher chemical resistance is required - 500F maximum.
  • MICA graphite - asbestos replacement - 660 F maximum.
    • Do not use in refineries, chemical plants or any flamable media
• Guide ring - carbon steel and electro-plated, standard thickness 0.125" (1/8")
  

  • Inner ring - used in high pressure applications to avoid over compression. Not standard on spiral wounds gaskets. The inner ring is made of the same type of materials as the guide ring.
