Product Description
Accept customize any size of graphite ring sleeve, ODM OEM is available !
Graphite rings are widely used in various industries due to their excellent properties. The main use of graphite rings is as a sealing element in pumps and valves. They are also used in other applications such as bearings, heat exchangers, and electrical contacts. The size of graphite rings can vary depending on the specific application.
The melting point of graphite is 3652ºC~3697ºC, the boiling point is 4827ºC, and the coefficient of thermal expansion is small.The electrical conductivity of graphite is one hundred times higher than that of general non-metallic,and the thermal conductivity exceeds that of steel, iron, lead and other metal materials.Acid and alkali resistance and corrosion resistance.It can withstand changes in temperature at normal temperature without breaking.
