Self-spreading ceramic composite pipe is manufactured by self-spreading high temperature synthesis - centrifugal method. Is to put the steel tube in the centrifuge tube mold, in the steel tube to add iron red and aluminum powder mixture, this mixture in the chemical known as aluminum thermite, when the centrifuge tube mold rotation reaches a certain speed, by a spark ignited aluminum thermite, aluminum thermite immediately combustion of their own, the combustion wave spreads rapidly, in the spread of the violent chemical reaction.
Self-spreading ceramic composite pipe performance characteristics:
1. Good wear resistance
Self-spreading ceramic composite pipe lined with corundum ceramic (a-AL2O3), Mohs hardness up to 9.0 equivalent to HRC90 or more. Therefore, metallurgy, electric power, mining, coal and other industries have high abrasion resistance to the transport of abrasive media. Confirmed by the industrial operation: its wear-resistant life is ten times or even dozens of times the quenched steel.
2. Small running resistance
Self-spreading ceramic composite pipe due to the smooth inner surface, and never rust, not like seamless steel pipe inner surface with convex helix exists.
3. Corrosion resistance, anti-scaling
Self-spreading ceramic composite pipe due to the steel ceramic layer (a-AL2O3), is a neutral quality. Therefore, it is acid and alkali resistant and seawater corrosion resistant, and at the same time has the characteristics of anti-scaling.
4. Good temperature resistance
Self-spreading ceramic composite pipe due to the corundum ceramic (a-AL2O3), a single stable crystalline organization. Therefore, the composite tube can be in the -50 - 700 ℃ temperature range of long-term normal operation.
5. Easy installation and construction
Self-spreading ceramic composite pipe due to the light weight of the pipe, and good welding performance. Therefore, it can be welded, flanged, fast coupling, etc., construction and installation is convenient, and can reduce installation costs.
