Asbestos graphite packing

Graphite packing
First, let's look at the basic structure and materials used to make this Peking.
This packing is composed of asbestos, refractory grease and graphite powder.

Asbestos: Asbestos is one of the most important minerals used to make refractories. The most important component is asbestos silicate. One of the most important properties of asbestos is the heat tolerance between 550 ° C and 650 ° C. This temperature tolerance varies depending on the conditions. Asbestos is used in most refractory materials due to its good heat tolerance and stabilization of system temperature. Of course, one of the most important issues about asbestos is; Environmental hazards and harms of asbestos. One of the diseases that asbestos dust causes in humans is lung cancer. For this reason, the use of asbestos has greatly decreased. Of course, the use of asbestos in places that humans do not deal with, is not prohibited. Another way to use asbestos is to control its dust; The same thing is done with graphite in graphite asbestos packing.
Refractory grease: Refractory grease is a combination of natural and synthetic oils that are used to further lubricate parts and industrial sealants that deal with heat. The most important properties of refractory grease can be anti-corrosion, lowering the drop point, stabilizing, strengthening and. . . Cited .
Graphite powder: Graphite is one of the carbon deformations that is used in many industries due to its softness. The most important properties of graphite are: high resistance, anti-corrosion, good heat resistance, natural lubrication, good electrical and thermal conductivity, very good chemical stability, good pressure resistance and dozens of other features. Due to these properties, this mineral is used raw in many industries. Some of the applications of graphite are: lubrication, aerospace applications, suitable coating, application as a coating layer for sealing packages, used as electrical applications, used for metallurgical applications and dozens of applications. Another important industry.

Asbestos graphite refractory packing

Refractory packing of asbestos graphite is woven from refractory asbestos fibers. In order to withstand more heat and prevent the spread of dangerous asbestos particles, oil and graphite grease have been used in their preparation and are available in two types:
1- Asbestos refractory packing impregnated with oil and graphite
2 - Asbestos refractory packing impregnated with grease and graphite
In order to maintain better strength, cohesion, sealing and sealing, in making this refractory packing, oil or grease with graphite powder is used and you can order any of these products according to your needs. Other features of asbestos graphite refractory packing include very good density and excellent flexibility of this refractory packing in seals.
Also, this product is considered as one of the asbestos green packs due to the presence of several protective layers on its asbestos yarn; This means that the risks of using it for humans and the environment are much less than pure asbestos. The temperature tolerance of this packing is 800 degrees Celsius, but the safe temperature for its use is 550 degrees Celsius. This seal is a suitable and ideal choice for use in high temperature valves, steam, butane and propane gases, oil vapor, furnace oil and so on. Asbestos graphite refractory packing is widely used in all kinds of flanges, valves and boilers, etc.
