A. Alumina tube is non-flammable, stainless, strong and not easily damaged, and has excellent performance that other organic materials and metal materials cannot match.
B. The abrasion resistance of the alumina ceramic tube is the same as that of corundum, reaching Mohs hardness level 9, and the abrasion resistance is equivalent to that of super hard alloy.
ALUMINA CERAMIC TUBE
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.
Our alumina ceramic tubes are exported to more than 30 countries. The quality of our products is deeply liked by customers. Crucible products are also purchased by many university laboratories and mining laboratories. Parts products are also ordered by many large machine companies.
Alumina ceramic tube uses
Alumina ceramic tube is mainly used for protection tube and insulation tube of thermocouple thermometer of temperature measuring instrument. Furnace tubes of industrial resistance furnaces, experimental furnaces and heat treatment furnaces; Chemical analysis of iron and steel: carbon and sulfur determination tubes; Other high temperature resistant, acid and alkali corrosion resistant insulated instrument components.
Structural type: the protective tube has two types: closed and open. There are two types of insulating tubes, round and oval, and they are divided into single-hole, double-hole and multi-hole. In addition, there are threaded pipes and prismatic pipes.
The picture is about the industrial ceramic tube of 4 bores tube.
Our company can produce the industrial ceramic tube for molti bores, the 2,4,5,6, even we produce the 12 bores. The industrial ceramic tube can maintain insulation at 1800C.
Product Features
▪ Alumina furnace tube made by 99.3%-99.7% high purity alumina
