HIGH PURITY ALUMINA CERAMIC TUBE
My factory looking for distributors.
Insulation:
The material of alumina ceramic tube has excellent insulation properties, low frequency loss and good high frequency insulation. The heat resistance of alumina ceramic tube has small thermal expansion coefficient, large mechanical strength, and good thermal conductivity.
Alumina ceramic tube uses:
The high purity 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.
Recommended products:
Protective tube:
For thermocouple External protection tube. insulation,
High temperature resistance,Good air tightness
Ceramic boat：
Corrosion resistance, high fire resistance and good chemical stability.
Used in laboratory extraction, burning, mineral, chemical and other industries.
