The graphite packing with antioxidant outer crocheted Inconel wire is reinforced by specially treated graphite strips and each metal mesh with Inconel wires outside, which is woven to form a dense and soft packing. The packing is treated with lubricant to reduce the friction on the rod, with stable chemical properties, easy molding, good lubrication performance and high thermal conductivity. It is not easy to harden and is inert to chemicals. There is no danger of extrusion and deformation of packing at high temperature, and the leakage control is consistent, which is suitable for seals of high temperature and high pressure valves.
1. Product Feature
This high-performance packing adopts high-purity antioxidant flexible graphite core, with outer crocheted Inconel alloy wire reinforcement. With professional antioxidant treatment, it delivers ultra-high temperature resistance, excellent anti-oxidation stability and outstanding structural toughness. The Inconel wire layer effectively prevents extrusion, deformation and carbon oxidation loss under long-term high-temperature oxidation environments, featuring stable compression recovery, low friction coefficient and greatly extended service life.
2. Applicable Equipment
Suitable for ultra-high temperature and high-pressure rotary pumps, reciprocating pumps, boiler valves, high-temperature pipeline expansion joints, industrial furnace equipment and heavy-duty stirring devices. It can be used independently or matched with other soft packings to improve anti-extrusion capability and overall sealing stability.
3. Applicable Industries
Widely used in thermal power generation, metallurgy, petrochemical, nuclear industry, high-temperature boiler manufacturing, aerospace and other heavy industrial fields with high-temperature and oxidative harsh working conditions.
4. Compatible Media
Applicable to water, superheated steam, high-temperature hot oil, air, flue gas, and mild acid and alkali media. It keeps stable sealing performance for a long time in high-temperature oxidative gas and non-strong corrosive liquid environments.
5. Typical Working Conditions
Specially developed for extreme working conditions with ultra-high temperature, high pressure, continuous operation and severe oxidation. It effectively solves the problem of easy oxidation and failure of ordinary reinforced graphite packing in high-temperature oxidative environments, and is suitable for working scenarios with frequent temperature fluctuations and long-term oxidative erosion.
