Pure graphite packing
Pure graphite packing, as its name implies, is made of graphite, which has considerable flexibility.
Graphite packing has a high purity of graphite, which is mixed with two percent carbon during the process, which minimizes the fragility of the packing.
The main material of this packing is graphite fibers, which show good resistance to destructive rays such as X-rays and ultraviolet rays and have a low coefficient of friction; On the other hand, it is resistant to rust.
If you need to strengthen this packing, you can increase the pressure tolerance by adding more carbon to the packing or adding Teflon to it or combining wires such as steel wire, steel wire, nickel wire and copper wire among the packing. Be a product.
The most prominent features of graphite packing are:
Used in all environments
In an environment with steam and humidity, heat tolerance up to 650 ° C
Preservation of shape and structure at low temperatures up to -200 ° C
In dry environment can withstand temperatures up to 860 degrees Celsius, in long-term use can withstand temperatures up to 550 degrees Celsius
Resistance to chemical erosion, maintaining efficiency and good performance in alkaline and acidic environments
Ability to control pressure
Good mechanical resistance and resistant to tearing, tension and abrasion
Resistant to destructive rays such as X-rays and UV
Oxidation resistance up to 400 ° C
Good electrical conductivity
Durability and long life
