Ultra-high temperature packing is woven from high-quality synthetic fiber with stainless steel wire, nickel wire, and nano-graphite. It has a fine structure and has the advantages of good high temperature and high-pressure resistance, low thermal conductivity, and non-combustibility. Under certain circumstances, the instantaneous max. temperature resistance can reach 1400°C. Ultra-high temperature packing is widely used in water, steam, and other media in harsh environments with ultra-high temperatures and high pressure. It is used for thermal insulation, fire protection of pipelines, etc., and static sealing of containers, heaters, manholes, furnace door heaters, high-temperature flanges, etc. It performs well under high-temperature working conditions in steel plants and is recommended for blast furnace combustion valves in steel plants.

Produktintroduktion:
High-Temperature Nano-Graphite Gland Packing is composed of ultra-fine graphite powder, nano-scale graphite particles or high-purity graphite fiber and other reinforcing materials (such as PTFE, aramid, carbon fiber, etc.). Through fine nanotechnology treatment, the graphite particles have better lubricity and stronger high temperature resistance, thereby significantly improving the sealing, corrosion resistance and wear resistance of the filler.
Main features
High temperature tolerance: Suitable for extreme high temperature environments, the temperature can reach 550°C (conventional graphite filler) to 1000°C (high-purity nanographite filler), and has good stability during long-term use.
Corrosion resistance: Graphite itself has good acid, alkali and oxidation resistance, so the filler can be adapted to a variety of chemical media.
Low friction coefficient: Nano-graphite material has an extremely low friction coefficient, which can effectively reduce wear and heat accumulation during the sealing process.
Strong sealing: The microstructure of nanographite makes the filler have stronger sealing performance, which can effectively prevent fluid leakage and reduce energy loss.
Pressure resistance: Maintain stable sealing performance under high pressure conditions to prevent leakage and system failure.
Excellent anti-oxidation performance: It can adapt to oxidizing gas or liquid environments without graphite shedding or corrosion.
Specific parameters
Temperature range: -200°C to 1000°C (varies based on material and design).
Sealing pressure: Can withstand pressures up to 100 MPa (customized according to equipment requirements).
PH range: Generally suitable for media with pH 1-14.
Friction coefficient: Usually between 0.05-0.15, depending on usage conditions.
Linear sealing: Excellent sealing, effectively preventing fluid leakage.
Expansion coefficient: Graphite material has a small expansion coefficient, so it is suitable for environments with large temperature differences.
