Spiraltherm Graphite 9584 spiral wound gaskets are made of a V-shape profiled stainless steel tape with spiral wise winded graphite filler tapes. Both ends of the steel tape are spot-welded. These metallic gaskets are manufactured in several combinations of materials with a wide range of dimensions and geometry. Spiraltherm Graphite 9584 spiral wound gaskets are widely used in refineries, the chemical and petrochemical industry as well as in the power generation industry.
  • Solid construction
  • Easy handling
  • Excellent load distribution
  • Easy installation
  • Exceptionally high operating reliability
  • Great resilience (approx. 10 % of un-compressed height)
  • Stability and sealability even under severe conditions
  • Stable and reliable sealing performance even under frequent pressure cycle
Pressure: p = up to 400 bar (Class 2,500 lbs) for flanges according to EN or ASME standard
Temperature: t = -200 °C … +550 °C
(higher temp. possible in inert atmosphere)
Chemical resistance: pH = 0 … 14
Optimised roughness grade: RZ = 12.5 - 30 µm
Metal winding:
Stainless steels - most common are: AISI 316L, 316, 304, 304L, 321 (1.4541), 316 Ti (1.4571), 347…
Windings are also available e.g. in Monel®, Incolloy®, Hastelloy®, Titanium…
Filler materials: To prevent oxidation at elevated temperatures, a high quality graphite with oxidation inhibitor can be offered.
