Alumina ceramic oblong tube
Aluminum oxide ceramics, silicon nitride ceramics, zirconia ceramics
Alumina ceramic pipes are lined alumina ceramic pipes prepared by the thermite-centrifugal method. The high temperature generated by the reaction itself is used to melt the reaction products and separate under the action of centrifugal force to form alumina lined ceramic pipes. The energy consumption is low and the process is easy. few.
The ceramic pipe combines the advantages of high alumina hardness, good chemical inertness and steel. It has excellent wear resistance, corrosion resistance, heat resistance, thermal shock resistance and mechanical shock resistance, and its service life is more than 15 times longer than that of ordinary steel pipes. Alumina ceramic pipes are generally white.
The characteristics of alumina ceramic long round pipe : A. Good wear resistance: the lining ceramic layer of alumina ceramic elbow is wear-resistant engineering ceramics, its hardness (HRA) ≥ 84, and its wear resistance is high chromium wear-resistant cast iron alloy More than 10 times that of pipe fittings. With a 5mm thick ceramic layer, its actual wear-resistant service life will be equivalent to 50mm thick wear-resistant cast steel. B. Corrosion resistance: Alumina ceramic materials with different contents are selected, which have excellent anti-corrosion properties for different corrosive media, and are resistant to strong corrosive media such as acids, alkalis, and salts, and halogen salt corrosion.
C. Good high temperature resistance: Alumina ceramic itself has the ability to withstand high temperatures above 1700 degrees Celsius, and is especially suitable for lining high-temperature burners and other equipment. The lining engineering ceramics have high strength, high hardness, and excellent wear resistance and corrosion resistance.
D. Reduce engineering cost: Alumina ceramic pipes are mainly used to convey liquid-solid two-phase flow substances and corrosive media with particles, and are used to replace expensive stainless steel pipes, high-chrome cast steel pipes, and hard alloy wear-resistant pipes. It can directly reduce the engineering cost and prolong the service life at the same time. The product is cost-effective, which can save the cost and time of maintenance and replacement of materials. The manufacturing process is simple; the weight is light, and the transportation and installation are convenient.
