Purpose and area of application

Sealing of mobile and fixed units of locking accessories applied in heat power engineering, water supply, plants of chemical industry instead of composite materials on fluorplastic base.

Technological features of the materials

Water-repellency treatment of graphitic fibres cords by oligomer and high-molecular components according to solution or plasma-chemical technology and provides high wear-resistance of friction pair “rod-seal”.

The sealing kits represent a collection of rings from water-repellent graphite which ensures mating sealing with cords from the top and bottom.

The rings have the designed geometrical sizes with dia in the range of 12 - 360 mm and thickness in the range of 10 - 25 mm.

Technical characteristics

  • Increase of:
    • strengh................ by 1,2-1,3 times
    • heat stability................by 150-200 0C
    • wear-resistance (in comparison with starting fibres).......by 1,5-2 times
  • Operating temperature, 0C...............up to 600
    ? (inert atmosphere), 0C..................up to 3000
  • 1000 h without special servicing
  • Stability to operating mediums including concentrated and diluted solutions of salts, acids and alkalis.
