Pure graphite packing

Some also know this type of packing as pure graphite refractory yarn. Pure graphite packing, as its name implies, is made of high quality expanded graphite fibers with a purity of over 96%. We should know that the main material in the structure of this packing is pure graphite.

Pure graphite packing
First, let's talk about the structural nature of this packing
This packing uses carbon fiber and graphite in its structure.
Graphite: Graphite is one of the other forms of carbon that is widely used in industry. The main structure of graphite is formed by the placement of 6 carbon atoms. The most important feature of graphite; Its structure is layered. Pure graphite layers are placed in parallel on top of each other so that the underlying layers are connected to the upper layers by graphite dust. This feature causes complete sealing as well as strength against high temperatures. The most important features of graphite are: high thermal resistance, anti-corrosion, tensile strength, structural stability in chemical environments, resistance to hazardous radiation, low friction and pressure resistance. The most important application of graphite is in nuclear reactors.
Carbon fiber: Carbon fiber is one of the most widely used fibers in the industry. These fibers are widely used to make composites and heat shields. Carbon fibers have a much higher tensile strength than other refractory fibers and also have a much higher coefficient of expansion. The most important properties of carbon fibers are resistance to strong acids and bases, resistance to ultraviolet and X-rays, strength to fatigue and. . . Cited . The most important use of carbon fiber in the military industry is to make resistance shields.
Pure graphite refractory packing:


Some also know this type of packing as pure graphite refractory yarn. Pure graphite packing, as its name implies, is made of high quality expanded graphite fibers with a purity of over 96%. We should know that the main material in the structure of this packing is pure graphite. This type of packing also has a very high flexibility.
Features of this type of packing
Researchers have found that the thermal resistance of this type of refractory packing is about 650 degrees Celsius. This packing is also able to maintain its stability at a temperature of minus 220 degrees Celsius. The chemical resistance of this packing is from 1 PH to 14. This product has a very low coefficient of friction and this feature has greatly increased its applications. This packing is the best type in the field of sealing and is resistant to pressure and works for installation in valves that work with steam or other liquids.
Applications of pure graphite packing
In general, this packing is very suitable for use in all environments that are accompanied by pressure or steam and is mainly used to prevent the outflow of fluids. This packing can be used in chemical compounds (except alkaline and fluorinated metals), motor shaft (low speed), piston pump, centrifuge and sealant. Therefore, this packing has a variety of uses, the most important of which are the following.
1- Use for thermal sealing of tanks of petrochemical, metallurgy, power plants and marine facilities
2- Use for sealing high pressure pumps in gas power plants
3- Used to seal all separation valves in nuclear reactors
4- Use to seal all types of laboratory tanks in chemical environments
5- Use for all kinds of applied materials, all kinds of industrial torques
