The characteristics of the wear resistant ceramic composite tube

1. Overview of wear resistant ceramic composite tube

Ceramic pipe is made of the self-propagating high temperature synthesis, centrifugation.Is put seamless pipe inside the pipe die of centrifuge, add red iron oxide and aluminum powder mixture in the composite tube, the mixture in a chemical called thermit.Centrifuge pipe die rotate after reaching a certain velocity, lit by a Mars thermit, thermit immediately their combustion, the combustion wave spread quickly, in the spread of violent chemical reaction, and gives off a lot of calories.This heat such as under the adiabatic condition, adiabatic temperature can reach 3860 k and 3600 k, it makes the composite tube original material and the products after the reaction, is the melting point is 2045 ℃ of alumina (commonly known as corundum) have all become molten.

2. The application of wear resistant ceramic composite tube

Wear resistant ceramic pipe with excellent abrasion resistance, heat resistance, mechanical and thermal shock resistance, easy to welding and installation, especially suitable for wear and erosion serious occasion, conveying, such as coal, metallurgy, coal, mining, geological materials industries such as pipelines.According to the electric power, coal, metallurgical and other industrial departments use for many years, compared with the ordinary seamless steel tube, the service life of wear resistant ceramic composite pipe into ten times growth, can replace, alloy pipe, organic material liner, etc., is a kind of ideal high wear-resisting, high temperature resistant pipe.

3. The characteristics of wear resistant ceramic composite tube

1, good abrasion resistance: ceramic corundum ceramic pipe by dry lining layer, mohs hardness can reach 9.0, the equivalent of HRC90 above, therefore to metallurgy, electric power, mine, coal and other industries transmission by the grinding media have high abrasion resistance.

2, run small resistance: ceramic pipe due to the table smooth, dense, and it will never rust, by the relevant inspection test unit internal surface roughness and water resistance properties, its degree of surface smoothness is better than that of any metal pipes, water resistance coefficient is 0.0193. A bit lower than the seamless tube.So the tube has the characteristics of running resistance small, can reduce the operation cost.

3, low engineering cost: ceramic lined composite steel pipe because of light weight, improve the service life, so as to reduce the cost, handling cost steam-water, average investment decline. Wear Resistant Ceramic pipe project total cost and cast stone pipes.Compared with wear-resistant steel pipe construction cost down 20-30%.

4, corrosion resistant, anti fouling: this product for ceramic layer (a - AlO), is a neutral substances.So the acid and alkali resistance and seawater corrosion, and at the same time has the characteristics such as scale prevention.

5, good heat resistance performance: the ceramic-lined steel composite pipes can be in - 50 ~ 900 ℃ temperature range of normal operation for a long time, material linear expansion coefficient of 6 ~ 8 x10 - / ℃.

6, convenient installation: products are light weight, and compared with other pipe diameter, can save 20 ~ 30%, steel and heat resistance and mechanical impact resistance and other good comprehensive performance, can be used welding, flange connection approaches such as rapid, convenient installation, construction can reduce the cost of installation.
