Features

Statotherm R profile rings R901/B are made from permanently elastic, expanded graphite (purity >99.85 %) without binders or fillers. Therefore these profile rings are almost maintenancefree, for severe temperature changes and /or extreme temperatures, which cannot be handled by elastomeric O-rings.

Advantages

  • Good deformability
  • Permanent resilience
  • Long-term flexibility
  • Good structural strength

Operating range

Temperature: t = -200 °C … +500 °C
steam: +550 °C
Chemical resistance: pH = 0 … 14
Ash content: < 0.15 %
Chloride content: < 20 ppm
Density (raw material): 0.7 or 1.0 g/cm3
Resistant to almost all organic and inorganic acids, alkalis, oils and solvents Optimised roughness grade: RZ = 10 - 40 µm

Standards and approvals

  • TA-Luft

Variants

R901/B5: density 1.3 g/cm3
R901/B6: density 1.4 g/cm3

R901/B8: density 1.8 g/cm3
R904/...: reduced sulphur content < 200 ppm

Notes

The deformation of Statotherm profile rings is permitted in axial direction only. The construction of groove must be designed to avoid any radial deformation of the sealing ring as this may destroy it.
