HP silicon nitride ceramic rod
Specifications
Usage:
Electrical industry, ceramic industry, oil industry, food industry, medical industry, chemical industry etc.
Characteristic:
Resistance to strong acid, strong alkali, salt and gas of deleterious, long life, high hardness, resistance to wear, especially resistance to hydrofluoric acid.
Silicon nitride ceramic rod, is wear resistant, anti-corrosion, resistant to high temperature, and can endure impact. Silicon nitride ceramic rod has a service life about 7~10 times longer than metal rod. As critical part in rod pump, silicon nitride ceramic rod is widely used in electrical industry, ceramic industry, oil industry, food industry, medical industry, chemical industry etc. to replace metal rod.
It is shown that by applying silicon nitride ceramic rod in oil industry, production capacity of oil could be largely improved as well as the cost could be cut down.
Our silicon nitride ceramic rod is produced by cold iso-static pressing and assembled with our unique method. The rod has excellent properties and never drops off.
Our production range is 3~140mm diameter and 10~300mm length.
If you are interested in this product or just want to know more about ceramic products, never hesitate to contact us.
