Industrial ceramic tubes

My company produced alumina thermocouple protection tube, all imported alumina by modern technology, in the 1830-degree heat made 8-hour burn fine. Products and fine texture, smooth and long-term use in the 1650-degree bend, the maximum temperature up to 1850 degrees (short term), high temperature corrosion resistance, insulation, good acid, alkali, high temperature vacuum can be long-term use. No leakage, the same type. Fast heat conduction, thermal shock resistance and long service life. Alumina content of 100 molecules 99.5-99.7. Mainly used for high-temperature sensors protect the casing. Thermocouple protection tube is mainly used for temperature measurement devices to protect, so that temperature components and isolation, reduce or prevent the temperature measuring devices in the course of the outside world, substance erosion, oxidation and collision damage. My company produced 99.7,99.5 alumina thermocouple protection tube is my company's early 2007 launch of new products and processes through the production and processing of ceramic-ceramic alumina ceramic tubes popular Europe and the United States. Japan and South Korea a user's flat, it looks Smooth, color uniformity, strength is 20 times the normal ceramic tube. in oxidizing atmosphere using automatic formation of anti-oxidation film, to prevent corrosion, thermal shock resistance is good, in 1500 - at room temperature six times does not burst, long-term use temperature of 1650 degrees maximum temperature 1850 degrees. Refractoriness 2055 the volume density of 3.92 degrees. breakdown voltage 15KV/MM, Mohs hardness 9, AL2O3 content of 99.5-99.7 per cent. Tip: Use this product must be preheated.
