Properties
1. Strong corrosion resistance: high-aluminum ceramic tube has strong corrosion resistance and can operate stably for a long time in the corrosive environment of chemical media.
2. Good high temperature resistance: high-aluminum ceramic tube can maintain long-term stability and performance in high temperature environment without degradation.
3. High mechanical strength: high aluminum ceramic tube has very good mechanical strength and can remain stable under high pressure, heavy load and other conditions.
4. Good insulation performance: high-aluminum ceramic tube has good insulation performance, so that it can be widely used in high temperature and high voltage electrical equipment.
5. Long service life: high aluminum ceramic tube has high wear resistance and wear resistance, long service life, reduces the frequency of replacement and maintenance, and reduces the cost of use.
6.Wide application: high aluminum ceramic tubes are widely used in transportation, storage and production in petrochemical, electric power, metallurgy, mining and other industries
Application
- Metallurgical industry: high-aluminum ceramic pipe can be used in the smelting process of non-ferrous metals such as iron, steel, copper, and aluminum, as pipelines, throats, liners, sheaths, etc.
- Chemical industry: In chemical production, due to the nature of the medium and its related process requirements, conventional materials are difficult to meet, so high-aluminum ceramic tubes need to be used.
-Power industry: high-aluminum ceramic tubes are widely used in the manufacturing process of electronic ceramics, optical ceramics, solid electrolytes and other products in the power industry.
- Petroleum industry: high-alumina ceramic tubes are widely used in oil exploration and exploitation. For example, for storage tanks, oil storage towers and other pressure-bearing equipment, high-aluminum ceramic tubes can be used as liners or bushings.
-Construction industry: high-aluminum ceramic tubes can also be used in the construction industry in terms of fire prevention, heat insulation and wear resistance. For example, furnace shells and sliding parts for buildings.
- Machinery manufacturing industry: high-aluminum ceramic tubes can be used to manufacture some very special machine parts, such as bearings, mechanical seals, ceramic tools and ceramic bushings for locomotives and ships.
-Casting industry: high-alumina ceramic tube can also be used in precision casting and accurate measurement aspects in the metal casting industry, for example, for casting pellet materials and molds and templates in superalloys.
