Graphite Rings
Manufactured by molding flexible graphite or flexible graphite braided foil, HPMS
graphite rings are designed to provide excellent sealing functions for valves, pumps,
compressors and chemical instruments.
Characteristics:
* Excellent thermal stability: Resistant to low
and high temperatures (-200 to 650 degree
C) in oxidation environment and 3000
degree C in inert or reducing environment.
* Chemically inert: Resistant to fluids with pH
range of 0-14 (except strong oxidizers
such as nitric or sulphuric acid).
* Low coefficient of friction
* Easy of installation
Applications:
* High temperature, high pressure steam
* Hot water, oil, heat exchange fluids
* Low temperature liquids
* Organic and inorganic fluids except strong
oxidizer such as nitric or sulphuric acid
* High temperature and pressure liquid valves
* High temperature and pressure gas valves
* High temperature joints
* Packing rings, turbine rings and piston rings
* Special vacuum furnace applications
Availability:
* Carbon content 98% to 99.5%
* OD: 2-1100 mm
* Thickness: 0.006” to 0.8”
* Density: various densities up to 1.6 g/cc
