1. Wear resistance: The inner ceramic layer of the ceramic wear-resistant tube is corundum, and the Vickers hardness is 1300-1500HV, which is equivalent to HRC90 or above, so it has high wear resistance to electricity and any medium conveyed by the mine.
2. Corrosion resistance and anti-scaling performance: Because the corundum lining is a neutral material, it has strong acid, alkali, tank corrosion and seawater corrosion resistance, and has anti-scaling performance at the same time.
3. Low loss of running resistance: The ceramic wear-resistant pipe has been tested for the resistance characteristics of powder conveying, slag conveying and ash conveying by Beijing Science and Technology. The results are as follows:
Because the inner surface of the ceramic wear-resistant pipe is smooth and does not rust, the resistance coefficient of clean water is smaller than that of the seamless pipe of the same specification, so the running resistance is small and the running cost can be reduced.
4. Good temperature resistance: The ceramic wear-resistant pipe can be used normally for a long time in the temperature range of -50~900℃, and the linear expansion coefficient of the material is 6~8×10-6/℃. Therefore, it has better thermal shock stability.
5. Engineering cost and service life: The ceramic wear-resistant pipe is light in weight and reasonable in price. The project cost is equivalent to that of cast stone pipes, 20-30% lower than that of wear-resistant alloy cast steel pipes, and the service life is 15-20 times that of ordinary steel pipes, and 8-10 times that of cast stone pipes. Ceramic wear-resistant pipes, It is 2 to 3 times that of the wear-resistant alloy tube, and the maintenance cost is reduced.
6. Easy installation and maintenance: The ceramic wear-resistant pipe is light in weight, which is 1/3 of the weight of the cast stone composite pipe with the same inner diameter, 20-30% lighter than the wear-resistant alloy cast steel pipe, and has good impact resistance and welding performance. Using welding, flange and flexible joints and other connection methods, installation and maintenance are particularly convenient.
1. High hardness
As measured by the Shanghai Institute of Silicate, Chinese Academy of Sciences, the Rockwell hardness of ceramic wear-resistant pipes is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.
2. Wear resistance
According to the measurement of the Institute of Powder Metallurgy of Central South University of Technology, the wear resistance of ceramic wear-resistant pipes is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.
According to our customer follow-up survey for more than ten years, under the same working conditions, the ceramic wear-resistant pipe can increase the service life of the equipment by at least ten times.
3. lightweight
The density of the ceramic wear-resistant pipe is 3.5g/cm3, which is only half of that of steel, which can greatly reduce the equipment load.
4. Wide range of applications
Including coal conveying, material conveying system, pulverizing system, ash discharge, dust removal system and other mechanical equipment with large wear and tear in thermal power, iron and steel, metallurgy, machinery, coal, mining, chemical industry, cement, port and other enterprises, it can also be used for There are different types of products to choose freely according to different market demands.
