Product description
The ceramic-lined steel composite pipe has exceptional resistance to abrasion. Its service life in materials transportation with hard abrasives is more than 20 times longer than in common steel pipe.
1. Ceramic Lined Steel Pipe and Elbows:
1.1 The Manufacturing Process of Ceramic Lined Steel Pipe and Elbows:
Ceramic (Corundum: a-Al2O3) lined abrasion resistant straight pipe and fittings are lined with highly abrasion resistant ceramic by SHS -------Self-propagating High-temperature Synthetic process.
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 degree.
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. They are widely used to convey highly abrasive material such as fly ash and any other fine powder material in mine, thermo power generating, coal processing plant, metallurgy, construction, etc. The service life is 10 to 20 times longer than normal steel pipe.
