SHS-self-propagating ceramic composite steel pipe and fittings, the new generation of wearable and corrosion resistant engineering pipeline, belongs to "863" Hi-tech Plan products. It is mainly used as grindable granule and corrosives in electric power, metallurgy, mining, coal, and chemical industry when transporting sandstone, coal fines, clinker, and aluminum liquid, etc. It is the ideal wearable and corrosion resistant engineering pipeline, with wear resistance 15 times higher than common steel pipe, smooth inner surface, and favorable liquor resistance.The composite pipe is composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500℃. The molten alumina produced from the reaction Fe2O3+2Al=2Fe+Al2O3 spreads on the inside wall of the steel pipe under the influence of a centrifugal force, then solidifies, so the ceramic layer has high density and smooth surface and bonds to the steel pipe.The ceramic-lined steel pipes have numerous exceptional properties including good resistance to abrasion, heat, mechanical and thermal shocks. The pipes are easy to weld and fixing. They are very suitable for the transport of abrasive materials and thus can replace cast ceramic pipes, alloy pipes, and resin-lined steel pipes. They have a wide variety of application in mining, power plants, water conservation and metallurgical, coal, petroleum, and building material industries.[b]Features:[/b]

[b]High abrasion resistant:[/b]

Vickers hardness of the corundum lining is HV1100 to1500, as high as that of tungsten-cobalt　hard alloys, and the abrasion resistance is 20 times as carbon steel pipes. Its rigidity is the highest among all oxides.

[b]Corrosion resistant:[/b]

Corundum is a neutral material, and is acid-proof and fouling -free.

[b]Heat resistant:[/b]

The pipe can work under circumstances of -50 to 800 degrees Celsius.

[b]Convenient installation:[/b]

It is much lighter than any other types of composite pipes, and can be welded or connected through flanges.

[b]Cost effective:[/b]

Ceramic-lined composite steel pipe can take the place of expensive stainless steel, titanium, nickel, cast stone or alloy pipes. Extended service life can also reduce maintenance cost.
