Advantages thermal conductivity, chemical stability and selflubrication Good sealing, wear resistance, and resistance to temperature, low temperature and pressure mechanical strength, low starting torque, and no damage to bearings materials Enhanced graphite wire as raw material Internal metal wires braided molding; graphite does not fall off Improved impact resistance Surface contains an oxidized overlay; acid and alkali corrosion resistance Smooth and tough Temperature and pressure ranges Temperature range: 328 degrees Fahrenheit to 850 degrees Fahrenheit in atmosphere; up to 1472 degrees Fahrenheit in steam Pressure range: 600 psi rotary to 4,000 psi valves, depending on environment Prevents leakage Compression packing seals protect pumps and valves from fluid leakage in static and dynamic applications Withstand temperatures and dissipate frictional heat away from the shaft, thereby increasing shaft speed and reducing leakage Use scenarios In chemical processing pumps handling hot and corrosive fluids, where reliable sealing and selflubrication are critical In steam line valve assemblies in refineries or power plants, where temperature and pressure demand robust leakage protection In oil and gas equipment with thermal cycling and vibration, where low starting torque and bearing protection are important
