VINER Industrial Alumina Ceramic 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 1 or 2 or 4 or 6 holes in the tubes. The size ranges from 6mm to 180mm for OD, and the length is from 10mm to 3000mm.
Selection of a variety of high-quality ceramic materials, hot, dry-pressed or injection molding, from high-temperature sintering of alumina ceramic tubes (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.
