Mechanical Carbon >>  Dynamic Sealing Elements
The special properties of Carbon materials have enabled them to give excellent results when used as dynamic sealing elements.

Some of these properties are:
  • High thermal resistance
  • High corrosion resistance
  • Outstanding resistance to thermal shock
  • Low thermal expansion
  • Good thermal conductivity
  • Low deformation up to extreme temperatures
  • Low neutron absorption cross-section
Carbon material can be used where any of the following special operating conditions occur:
  • Operating temperatures like outside the permissible limits for lubrications oils or greases.
  • The medium to be sealed must not be contaminated by lubricants oils or greases.
  • Seals are subjected to solvents or fluids lacking adequate lubricating properties.
  • The corrosion resistance of other materials is inadequate.
Dynamic Carbon sealing elements can be classified by their field of use as follows:
  • Sealing rings
  • Steam joint rings
  • Ball valve seats
  • Piston and guide rings
  • Piston rod seals
  • Packing rings
  • Turbine rings
  • Labyrinth rings
  • Metal-sleeved rings
  • Vanes
  • Metering rings.
