Is a professional manufacturer of ceramic wear-resistant products series of high-tech enterprises, focusing on industrial anti-wear technology research and development and application, the main production wear-resistant ceramic pipes, ceramic composite pipe, ceramic patch pipe, ceramic lined composite pipe, Ceramic elbow, self-propagating ceramic composite pipe, steel pipe lined with ceramic, wear-resistant ceramic pipe, wear-resistant ceramic, wear-resistant ceramic liner, wear-resistant ceramic shaped parts, wear-resistant ceramic products are widely used in thermal power, steel, cement , Smelting, coal, mining, chemical, port and other industries wear serious equipment.
Wear-resistant ceramic lining composite pipe using the main technology is the centrifugal casting composite ceramic technology. This technology is mainly used in the processing of ceramics is a high-temperature technology, in the conditions of high temperature in the elbow out of a layer of fine and uniform wear-resistant ceramic, wear-resistant lining ceramic composite pipe cast ceramic and Steel pipe to form an integrated structure, so when we use this wear-resistant ceramic elbow inside the ceramic and outside things are one, even if the use of a long time do not have to worry about the ceramic layer off.
Wear-resistant ceramic-lined composite pipe performance which?
1 Physical and mechanical properties
The self-propagating technology makes the ceramic composite steel pipe has a unique structure, which determines the excellent mechanical and mechanical properties of ceramic pipe, which not only wear resistance, corrosion resistance, high temperature, but also high hardness, strength and good resistance to mechanical shock and Thermal shock of the comprehensive performance.
2 excellent wear resistance
Ceramic-lined composite pipe with the traditional steel pipe, wear-resistant alloy steel pipe, steel tube, etc. have a fundamental difference. Ceramic steel pipe is the outer layer, the inner layer is dense a type of aluminum oxide (corundum). Corundum layer Vickers hardness of up to 1100-1500 (Rockwell hardness of 90-98), equivalent to tungsten cobalt cemented carbide. Wear resistance than carbon steel pipe is more than 20 times higher than it is usually bonded corundum grinding wheel performance is much better ceramic wear resistance is mainly by the inner layer of corundum layer, the Mohs hardness of 9, second only to Diamond and silicon carbide
3 excellent corrosion resistance
Ceramic tube containing more than 90% of aluminum oxide, aluminum oxide is neutral oxide, and acid, alkali, salt, not from the chemical reaction, acidity 96-98%, with high corundum porcelain acidity, At the same time, aluminum oxide is an inorganic substance, in the light, heat, oxygen and other natural environment long-term effect, there is no deterioration (ie, aging) problem. Ceramic layer can be acid, alkali and electrochemical corrosion, the determination of ceramic pipe corrosion resistance than stainless steel ten times.
4 running resistance is small
Ceramic-lined steel pipe as the inner surface of the smooth, and will never corrosion, nor as the surface of the seamless spiral pipe convex convex, the authority of the unit running ash resistance test, the water resistance coefficient of 0.0193, drag coefficient is less than ordinary steel pipe, Can reduce pipeline running resistance, reduce operating costs.
5 anti-fouling performance and reliable
6 high mechanical impact resistance
