SHS-self-propagating Process Overview:

The ceramic layer is formed by molten alumina at a temperature above ***0 degree Celsius. 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.

Features:

• High abrasion resistant: Vickers hardness of the corundum lining is HV***0 to***0, as high as that of tungste-cobalthard alloys, and the abrasion resistance is *0 times as carbon steel pipes. Its rigidity is the highest among all oxides.
• Corrosion resistant: Corundum is a neutral material, and is ac-proof and foulingfree.
• Heat resistant: The pipe can work under circumstances of **0 to **0 degrees Celsius.
• Convenient installation: It is much lighter than any other types of composite pipes, and can be welded or connected through flanges.
• Cost effective: 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.

Application:

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.
