Extruded Alumina Ceramic Tube/Pipe

My factory looking for distributors.

Advantages of alumina ceramic tubes

Alumina combines low thermal expansion, superior thermal conductivity, and high-compressive strength to make these furnace tubes thermal-shock resistant.

Alumina tube models come with elevated dielectric properties and offer a higher vacuum or protective atmosphere at an extreme temperature.

All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680

Application of alumina ceramic tubes

In more traditional industries, alumina ceramic tubes are commonly used in industrial ovens and furnaces.

Aluminum oxide ceramic tubes are insulators used for electrical connections.

Aluminum oxide ceramic tubes are used as heat-resistant brackets, sample racks, and drums for kilns.

Aluminum oxide ceramic tubes are used for spray tubes and gas nozzles.

Aluminum oxide ceramic tubes are used as protective tubes and ceramic insulators for thermocouples and RTDs.

Our alumina tubes offer:
--Extreme high temperature stability under reducing, inert, and high-vacuum condition under high temperature up to 1800°C.
--Extreme wear and abrasion resistance.
--Chemical corrosion resistance under high temperature.
--High dielectric properties.
--Protective atmospheres or high vacuum at high-temperature to eliminate contamination or impurity.
