Expanded Flexible Graphite Braided Packing Class A Pump Valve Packing Mechanical Seal Packing Waterproof and Anti-Corrosion for Pump Gland Or Valve Stem(Size:4×4mm,Color:Length: 9.8 Feet(3m))
【High-quality materials】: the use of enhanced graphite wire as raw material, the internal increase in metal wire (steel wire, copper wire, nickel wire) woven molding, graphite does not fall off, enhanced impact resistance, smooth surface toughness.
【Advantages】: excellent thermal conductivity and chemical stability and self-lubricating. Wear resistance, high and low temperature resistance, high pressure resistance, acid and alkali corrosion resistance. High mechanical strength, small starting torque, will not cause damage to the bearing.
【Prevent leakage】: Compression packing seals protect pumps and valves from fluid leakage in static and dynamic applications. Withstands high temperatures and dissipates frictional heat away from the shaft, resulting in higher shaft speeds and reduced leakage.
【Temperature, pressure range】:Temperature range -328°f (-200°c) to 850°f (455°c) atmosphere to 1200°f (650°c) in steam,Pressure range 600 psi (41 bar) rotary to 4, 000 psi (275 bar) valves, depending on the environment.
【Widely used】: dynamic and static sealing under high temperature and high pressure conditions. Suitable for sealing chemicals, corrosive substances, gases, oils, paper materials, solvents, liquids, water, steam, boiler feed water and condensate. Widely used in: refineries, power plants, chemical plants, steel mills, pharmaceutical plants, oil and gas, wastewater and other industrial applications.
