The Description of alumina ceramic tube
We make use of our technical ceramic materials to make ceramic tubes and ceramic rods by extrusion, dry pressing, hot pressing, and ISO pressing. These ceramic tubes and ceramic rods are widely used in temperature measurement equipment for the oil and gas industry primarily, additionally, other industrial heating applications. They are also used in some specialist aerospace applications.
Our ceramic rods and tubes are made from different grades of alumina, zirconia, steatite, mullite, all of which have good insulating properties and thermal conductivity, also they are resistant to chemistry.
We have been producing many selections of extruded standard tubes and rods in sizes from 0.5mm to 50m outside diameter, so we could manufacturer large diameter ceramic tubes via ISO pressed which the largest diameter up to 800mm.
With our own in-house comprehensive types of manufacturing equipment, we have capable of reach various toughest applications via high precision processing, including lapping, polishing, grinding, and CNC machining.
