High-Purity Expanded Graphite: Manufactured from 100% pure expanded graphite foil, braided into a resilient, square cross-section. It contains no binders or fillers that could degrade at high temperatures.
Extreme Temperature Tolerance: Maintains exceptional performance from cryogenic temperatures -240℃ up to 650℃ in steam (and up to 450℃ in oxidizing atmospheres).
Universal Chemical Resistance: Virtually inert to almost all industrial chemicals and solvents across the pH range of 0-14 (except for strong oxidizers like nitric acid).
Reinforcement Options: Available in pure form or reinforced with Inconel wire, Stainless Steel wire, or Carbon fiber for enhanced blowout resistance in high-pressure valve applications.
Zero Volume Change: Unlike fiber packings, flexible graphite does not shrink or lose weight over time, ensuring the seal remains tight without constant gland adjustments.
Superior Thermal Conductivity: Efficiently transfers heat away from the stuffing box, preventing localized overheating and extending the life of both the packing and the equipment.
Low Friction & High Lubricity: The self-lubricating properties of graphite ensure low stem torque, reducing wear on valve stems and pump shafts.
Non-Aging & Non-Brittle: Does not become brittle or lose its elasticity even after years of service in high-heat environments, making it ideal for critical safety valves.
1）High-Pressure Steam Valves
The industry standard for sealing main steam lines, control valves, and bypass valves in power plants.
2）Refineries & Petrochemicals
Sealing for heat exchangers, agitators, and reactors handling aggressive hydrocarbons and thermal oils.
3）Pulp & Paper
Ideal for high-temperature liquor pumps and chemical recovery systems.
4）Soot Blowers
Capable of withstanding the mechanical stress and thermal shocks inherent in soot blowing operations.
