Product Description
Alumina ceramic sleeve pipe is a ceramic sleeve with excellent insulation, high temperature, and wear resistance. It is mainly made of high-purity alumina powder through molding, sintering, and other processes.
Materials and characteristics
The main material of alumina ceramic sleeve pipes is alumina (Al2O3), the content of which is usually above 95%, and some products even reach a high purity of 99%. This material gives the ceramic sleeve excellent electrical insulation, high temperature, and wear resistance. Alumina ceramic sleeves also have good chemical stability and can resist corrosion from a variety of acids, alkalis, and organic solvents.

Application fields
Widely used in various occasions requiring high temperature, high pressure, and high insulation performance. For example:
Electronic industry: used to make high-frequency insulating ceramic sleeves, thermocouple ceramic protection sleeves, etc. to meet the requirements of electronic products for high insulation and high-temperature resistance.
Power industry: used to make insulating sleeves for power equipment to ensure the safety and stability of power transmission.
Chemical industry: used to make wear-resistant and corrosion-resistant sleeves for chemical equipment to improve the durability and service life of the equipment.
Other fields: such as metallurgy, machinery, automobile, and other industries, there are also applications of alumina ceramic sleeve pipes.
Molding process
The main molding methods for alumina ceramic sleeve pipes include dry pressing, isostatic pressing, injection molding, and casting. Different molding methods are suitable for products of various shapes, sizes, and complex shapes. Isostatic pressing is a commonly used molding method for alumina ceramic sleeves. Its green body is strong, easy to carry, and directly machined. In addition, the green body of isostatic pressing has a uniform density in all directions, small stress in the green body, reduced defects such as green body cracking and delamination, and small deformation of sintered products.
Customized processing
Alumina ceramic sleeves support customized processing and can be designed and manufactured according to the specific needs of customers. Customized processing includes customized drawing and processing of supplied materials, which can meet customers' personalized requirements for product shape, size, precision, etc.
Precautions
When using alumina ceramic sleeves, care should be taken to avoid friction or collision with hard objects to avoid damaging their surface. When used in high-temperature environments, care should be taken to control the temperature range to avoid exceeding its high-temperature resistance limit. During storage and transportation, care should be taken to keep the alumina ceramic sleeves dry and clean to avoid moisture and contamination.
How to choose the right alumina ceramic sleeve pipe?
Choosing the right ceramic sleeve pipe requires considering factors such as the use environment, working temperature, mechanical stress, chemical corrosiveness, and electrical performance requirements. For example, in a high-temperature environment, it is necessary to choose an alumina ceramic sleeve with high-temperature stability; in a highly corrosive environment, it is necessary to choose a material with better corrosion resistance.
What are the technical advantages of alumina ceramic sleeve pipes?
Ceramic sleeve pipes have many technical advantages, including high strength, high hardness, high-temperature resistance, corrosion resistance, etc. These characteristics enable alumina ceramic sleeves to remain stable in extreme working environments and have good insulation properties. In addition, it also has excellent tensile properties, no adverse effects on the environment, and excellent thermal insulation properties. These technical advantages make it widely used in various fields and favored by users.
