Jinyu High Alumina tubes are widely used in thermocouple protections and some are used in furnaces. We could design both open for two ends, and one open, the other closed. Also we could make with 2 or 4 holes in the tube. The size ranges from 3mm to 100mm for O. D., and the length is from 10mm to 3000mm. We can also design upon the customers' detailed requirements. Selection of a variety of high-quality ceramic materials, hot, dry-pressed or injection molding, from high-temperature sintering of alumina ceramic tubes, alumina ceramic rods (which can be mechanical or electronic finishing, the tolerances up to +/- 0.01mm. ), high hardness, insulation, wear-resistant, high temperature-resistant, hot and cold shock-resistant. Customers can request a special size and production. Alumina ceramic tube is mainly applied to wear, serious scour of material handling occasions, such as coal-fired power generation, metallurgy, coal, mining, industry, and other geological materials pipeline, as well as the use of electronic appliances such as insulation pipe; Alumina ceramic rods is widely used in the industry of resistance to temperature and thermostat, as a resistance ceramic matrix and two-metal thermostat used in ceramic-top column. Our factory supplys 99.7% High Purity Alumina Tubes. 1. Extreme high temperature stability under reducing, inert and high vacuum condition under high temperature up to 1800C. 2. Extreme wear and abrasion resistance. 3. Chemical corrosion resistance under high temperature. 4. High dielectric properties. 5. Gas tight for many applications to provide protective atmospheres or high vacuum at high temperature to eliminate contamination or impurity.
