The metal mesh significantly enhances extrusion resistance, resilience, and pressure-bearing capacity, making it ideal for demanding applications involving high pressure, high temperature, or particulate media.
Application media: high-temperature/high-pressure steam, hot water, hot oil, ammonia, hydrogen, organic solvents, weak acid/alkali solutions, and corrosive fluids containing trace solid particles.
Application Areas: Widely used for dynamic and static sealing in high-temperature, high-pressure valves, pump shafts, and agitator shafts across power (steam turbines, boiler valves), petrochemical (reactors, high-pressure pumps), fertilizer, metallurgy, and other industries. Ideal for conditions with pressure fluctuations, thermal cycling, or minor wear.
