Industrial ceramic tubes

99.7 9.95 alumina ceramics, is my company launched in early 2007, after the new product manufacturing process of glass-ceramics microcrystalline alumina ceramic tube euro-american. Japan, it's good user's appearance, strength, colour and lustre smooth porcelain pipe is 20 times. In oxidation atmosphere using automatic forming oxidation film, prevent corrosion, thermal shock resistance, good at 15-6 times no room temperature crack, long-term use of 165 degrees highest temperature 1850.
