Aluminum Oxide Ceramic Pipe
My factory looking for distributors.
Alumina ceramic tubes have a wide range of applications, involving high-temperature testing and analysis equipment in various industries, such as coal testing and analysis equipment, metallurgical powder testing and analysis equipment, and chemical and glass industry testing and analysis equipment.
Alumina ceramic tubes are mainly sold to: the United States; Europe; Southeast Asia; South Africa and other countries.
The factory can adjust the outer diameter and inner diameter of the alumina ceramic tube to fit the supporting products.
Alumina ceramics advantages:
Aluminum oxide ceramic pipe takes high-purity alumina as the main raw material, the aluminum oxide ceramic pipe has the characteristics of high temperature resistance, corrosion resistance, good heat conduction, oxidation resistance, no deformation and no shrinkage after high-temperature firing.
Aluminum oxide ceramic pipe can effectively prevent high-temperature solution from corroding electric heating elements (silicon carbide rod and electric furnace wire) and greatly prolong the service life of products. Widely used in glass kilns, electric furnace products, non-ferrous metal smelting, zinc and aluminum plants and other industries.
Instructions for use
When using alumina furnace tubes, it is best to control the heating and cooling rate to 5 degrees / minute, the slower the better.
Rapid cooling and rapid heating are one of the main reasons for the rupture of the alumina furnace tube. Our products have good resistance to quenching and heating.
Please keep the alumina furnace tube clean at all times, do not leave some samples in the alumina furnace tube, one side chemical reaction and cracking of the alumina furnace tube. It is recommended to put the test sample into the crucible and alumina furnace tube.
During lofting and sampling, it is best to be within 200 degrees and slowly push from the edge to the middle. High temperature sample delivery and sampling is also the main reason for corundum tube rupture.
Make sure to place mullite plugs on both sides of the alumina furnace tube to prevent heat radiation from damaging the silicone ring in the flange. The crucible should be placed in the middle of the alumina furnace tube.
