Ceramic liner Wear-resistant tube is a high-tech production technology-self-fuel high temperature clutch synthesis method. The tube from inside to outside by corundum ceramics, transition layer, steel pipe (seamless pipe, welded pipe) Three layers, ceramic layer is in 2,200 ℃ above high temperature formation of dense corundum porcelain (Al2O3), through the transition layer with the steel pipe formed a solid combination. Because of its high strength, good toughness, impact resistance, good welding performance and high hardness, high abrasion resistance, corrosion resistance and heat resistance, the composite pipe overcomes the characteristics of low hardness, poor abrasion resistance and poor toughness of ceramic steel pipe. The outer wall is 6-16 mm thick, and the inner wall is 3-8 mm. Pipe diameter range dn20-dn1500.
Ceramic Liner Wear-resistant composite pipe due to the full use of steel pipe strength, good toughness, impact resistance, good welding performance and corundum porcelain high hardness, high wear resistance, corrosion resistance, good heat resistance, overcome the steel pipe hardness low, poor wear resistance and ceramic toughness poor characteristics. Therefore, the composite pipe has good wear-resistant, heat-resistant, corrosion resistance and mechanical impact and thermal shock, good weldability and other comprehensive performance. Is the transportation of granular materials, grinding, corrosive media, such as the ideal wear-resistant, corrosion resistance pipeline. Widely used in electric power, mining, steel, cement, chemical and other wear-like industries. Model straight pipe, elbow, bend pipe, tee, the size of the head, in addition to the production of underwear tube, the use of the effect is very ideal. Can replace the alloy tube, cast iron and so on.
Good wear resistance
Ceramic composite pipe due to the inner lining of corundum ceramic (A-al2o3), the Mo hardness of up to 9.0 of the equivalent HRC90. Therefore, the metallurgical, electric power, mining, coal and other industries to transport the grinding medium has high wear resistance. The industrial operation confirms that its wear-resisting life is 10 times times or even dozens of times times that of quenched steel.
Small Operation resistance
SHS Ceramic Composite pipe Because of the smooth inner surface, and never rust, nor like the seamless steel tube inside the surface has convex spiral. After testing the internal surface roughness and water resistance characteristics of the testing units, the smoothness of the inner surface is superior to any metal pipe, the resistance coefficient is 0.0193, slightly lower than the seamless pipe. Therefore, the tube has the characteristics of small operating resistance and can reduce the operating cost.
Corrosion resistance, scaling prevention
Because the steel ceramic layer is (A-al2o3), it is a neutral trait. Therefore, with acid and alkali resistance and seawater corrosion, and at the same time with anti-scaling and other characteristics.
Good temperature resistance and heat-resisting performance
The corundum ceramic (A-al2o3) is a single stable crystalline structure. Therefore, the composite pipe can operate in the -50--700℃ temperature range for a long time. The material linear expansion coefficient is 6-8x10-6/0c, about 1/2 of the steel pipe. The material has good thermal stability.
Low construction cost
The ceramic composite pipe is light in weight and suitable for price. than the same inner diameter cast stone pipe weight 50% lighter than the wear-resistant alloy tube weight light 20-30%, and wear-resistant, corrosion-resistant, because of long service life, thereby supporting the hanger costs, removal costs, installation costs and operating costs reduced. Compared with the engineering budget and engineering practice of the Design Institute and Construction Unit, the cost of the pipe project is equal to that of cast stone, and the project cost is about 20% lower than that of wear-resisting alloy pipe.
Convenient installation and construction
Because of the light weight of the tube, and good welding performance. Therefore, welding, flange, rapid connection, such as the installation of convenient construction, and can reduce installation costs.
