Ceramic-Lined Steel Composite Pipe

The combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features as an abrasion resistant, heat resistant and corrosion resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry etc.. It has many advantages over steel pipes, cast stone pipes, and steel-plastic compound pipes.

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 the normal steel pipe.

It is the ideal product instead of steel or rubber lined pipe and elbow.

Wear-resisting comparative table of ceramic lined pipe

Advantages:

Good abrasion resistance
The liner is High quality wear ceramic with 95% Al2O3 which are sintered under 1700 ℃and the hardness are up to 85HRA which is 271.5 times of manganese steel or 1700 times of chrome steel plate. Special composite method and toughening formula ensure the ceramic not being too fragile to resist the impact of normal blocks.

Little loss during running

Low project cost
Light weight and longer lifetime to save the cost of support structure and handling charges. The charges is similar to basalt piping project, or 20-30% less than wear steel piping project.

Good thermal stability
-50 ~600 degree C is the ideal temperature.

Easy and fast to fix on site
Welding, flange, flexible joint are available.
