Pure Graphite Gasket
01
Product Description
It is braided from low sulfur expanded graphite yarn reinforced with cotton yarn or fiberglass. This packing provides good thermal conductivity, chemical resistance, and high flexibility. Additionally, it does not damage shafts and spindles due to its low friction coefficient.
Corrosion Prevention Graphite Packings
The corrosion inhibitor provides cathodic protection to valve stems and stem covers against corrosion.
02
Application Areas
Graphite packings have a wide range of usability throughout a facility. This material is used where sealing is extremely important under high pressure and high temperature conditions, such as:
- In hydroelectric power plants
- In paper mills
- In power plants
- In valves used in refineries and industry
- In pumps
- In expansion joints
- In mixers operating at high temperatures.
