GRAPHITE PACKING BEST CHOICE FOR HIGH TEMPERATURE AND HIGH PRESSURE APPLICATIONS
Graphite Packing is made of reinforced graphite. The reinforcing materials are various fibers or wires including steel wire, copper wire, nickel wire, carbon fiber, pre-oxidized wire, glass yarn and other reinforced graphite wire.
Graphite packing resists all chemicals across the entire pH range (except fuming sulfuric acid, aqua regia, fuming nitric acid and fluorine). It also has great lubricity and excellent thermal conductivity.
It is widely used in acid and oil production industries Its resilience makes it the perfect sealant for the fuel, chemical, and gas industries.

Graphite packing This packing is manufactured from high purity flexible graphite that is expanded and formed into a braidable yarn and then braided without binders or wire reinforcement. It also contains corrosion inhibitor to prevent the electrical-chemical reaction. The finished product retains all the inherent benefits of flexible graphite: heat resistance, chemical inertness, low friction, self lubrication, and conforms readily. The outstanding properties of gh-110 make it a truly multi-service packing capable of a wide variety of uses throughout a plant. It may be used in valves, pumps, expansion joints, mixers and agitators in the hostile environments of hydrocarbon processing, pulp and paper, power generation, metal-working and other industries where effective sealing is vital. 2kg or 5kg per spool

High- quality combination of PTFE with incorporated graphite and reinforced edges from armada yarn to prevent gap extrusions within the high pressure and temperature range. Good sliding velocity and thermal conductivity. It is recommended for piston pumps up to 500 bar long service live. It can be used to seal water. Sewage water. Hot water. Oils. Greases. Gases. Weak acids and alkaline solutions
Ptfe graphite packing Interlock braid, using ptfe/graphite yarn and a high temperature break-in lubricant yarn is formed from expanded ptfe in which fine particles of pure graphite have been encapsulated. The resulting packing combines the chemical resistance of ptfe with the heat dissipation characteristics of graphite, thus allowing much higher shaft speeds than conventional ptfe packings. It is chemically inert over the entire 0-14 ph range with these exceptions: molten alkali metals, flourides, aleum, fuming nitric acid, aqua regia, and other strong oxidizing agents. Gh-120 is an excellent general service and corrosive service packing. It is commonly used in pumps, valves, rotating and reciprocating shafts, mixers and agitators, and is especially designed for services involving surface speeds and temperatures higher than those that can be handled by pure ptfe packing. 2kg or 5kg per spool
