First many appreciate for the guidance provided by the customer of a century-old Japanese chemical company we cooperated with on the important data of our product performance. Through in-depth communication between our technical personnel, we found that there were the errors in the expression of the leakage rate in the performance index and changed it in time.

The reason why wear-resistant alumina ceramic tubes are called good ceramics is that they are not only wear-resistant, corrosion-resistant and high-temperature resistant, but also widely used in electric power, high-temperature furnace, vacuum furnace, electrode tube, chemical industry and other industries.

Alumina industrial ceramic insulation materials are widely used in the walls and roofs of various high temperature furnaces, which are both resistant to high temperature and heat preservation.

Due to its high temperature insulation, alumina industrial ceramics are used as the thimble and protective tube of thermocouples. The insulation used in atomic reactors is still excellent. In addition, the loss is small and the dielectric constant is small.

Due to its high temperature resistance, corrosion resistance, high strength and other properties, alumina industrial ceramics are used as steel casting sliding nozzle, crucibles and utensils for smelting rare and precious metals, special alloys, high-purity metals, glass wire drawing, and various high-temperature furnaces.

99%~99.9% alumina ceramics are only used for occasions with particularly high performance requirements.

99 alumina industrial ceramic tube refers to engineering ceramics with alumina content higher than 99%. According to the national standard GB/T5593-1999, alumina ceramic materials have high hardness, high strength and low expansion coefficient.

The advantage of alumina industrial ceramic pipe is its thermal mechanical properties, including expansion coefficient, thermal conductivity, thermal capacity, aging under the influence of thermal cycle and the ability to withstand higher temperatures.

Alumina ceramic tubes have the advantages of high mechanical strength, high hardness, low high-frequency dielectric loss, etc. Because of their wide source of raw materials, relatively low price, and mature processing technology, they are widely used in electronics, electrical appliances, machinery, textiles, aerospace and other fields.
