Introduction to ceramic composite abrasion-resistant lining tube

Ceramic pipe full name the ceramic-lined steel composite pipes, pipe, is to use high technology production process, since the high temperature combustion clutch synthesis manufacture.The pipe from inside to outside, respectively by three layer, transition layer and steel corundum ceramics, ceramic layer is above 2200 ℃ high temperature to form dense alumina porcelain (AL2O3), with steel tube forming strong through the transition layer.

Pipe has good abrasion resistance, heat resistance, corrosion resistance and mechanical shock and thermal shock resistance, good weldability and comprehensive performance.Is conveying grain material, grinding, corrosive medium such as ideal wear-resisting, corrosion resistant pipelines.And according to the electric power, coal, metallurgical and other industrial departments use for many years, compared with ordinary seamless steel tube, the service life of the lining of ceramic composite abrasion-resistant lining tube into 15 times growth, can replace cast stone pipe, alloy pipe, organic material liner, etc., is a kind of ideal wear-resisting pipe.

Ceramic composite wear-resistant liner pipe with the traditional steel, wear-resistant alloy cast iron pipe, cast stone and steel model, such as steel, rubber tube has essential difference.Ceramic tube outer steel tube, the inner layer is corundum.Corundum vickers hardness high: 1100 ~ 1500 (los) hardness is 90 ~ 98, the equivalent of tungsten cobalt hard gold.Wear resistance than high carbon steel tube more than 20 times, more than the usual binder of corundum grinding wheel is much more superior performance.

Ceramic composite abrasion-resistant lining tube features below:

(1) good abrasion resistance, lining of ceramic composite wear-resistant tube layer for corundum ceramic, mohs hardness above 9.0, the equivalent of HRC90 above, so on electric power, coal, metallurgy, mining transport medium has high wear resistance;

(2) the lining of ceramic composite wear-resistant pipe can in - 50 ~ 900 ℃ temperature range is a long timeOften run, linear expansion coefficient of the material (6 ~ 8) x 10-6 / ℃;

(3) small resistance loss;

(4) the project cost is low;

(5) easy installation and construction.

Ceramic composite abrasion-resistant lining tube in addition to the application in the coal-fired power plant ash, slag discharge pipe, powder, powder back outside, also widely used in mining, metallurgical and other industries.In these high wear work environment, this kind of pipe manufacturing products but also embodies the incomparable advantages of similar products, wear-resistant ceramic tube inherited the characteristics of the steel tube, due to the nature of the ceramic-lined steel composite pipe play, so it has high strength, good at the same time, impact resistance, welding performance to continue and develop the characteristics of steel pipe.

The ceramic-lined composite pipe in combination with the characteristics of the wear resistant ceramic, because of the wear resistant ceramic has good wear resistance, on the wear resistant ceramic lined composite steel pipe also has good performance, the wear-resisting ceramics also have high temperature resistant and bonding properties, so the ceramic-lined steel composite pipes has the same these features.
