1. The Manufacturing Process of Wear Resistant Ceramic Lined Steel Pipe and Elbows:
SHS-ceramic steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline which are produced in a way of Self-propagating High-temperature Synthetic process.
Wear resistant elbows are 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 elbow.
2.Features of Alumina Ceramic
Alumina is a cost effective and widely used material in the family of engineered ceramics. Alumina ceramics have been developed and optimized for maximum wear resistance and corrosion resistance. A high density, diamond like hardness,fine grain structure and superior mechanical strength are the unique properties that make it the material of choice for a wide range of demanding applications.Ceramic has uses similar to Cast Basalt but it has greater resistance to wear in high velocity applications and impact resistance in extreme dynamic systems .
