Alumina ceramic tile or tube lined steel pipe is produced by welding, pasting or interlocking system. 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 used in the variety of industries.
Full range of 92% Alumina ceramic tile or tube lined steel pipe for high wear area including straight pipes, bends, elbows, tees, Y-pieces, reducers, crosses can be available from our factory.
Regarding the connection ways, we can provide with the normal way of welding or flange or to customize according to the customer's requirements.

Advantages:
1) Good abrasion resistance
As the wear surface, the alumina ceramic is 9 Mohs hardness, whose wear resistance is 10 times that of hi-chrome cast iron alloy pipes. It can make little wear loss of the pipe during running, which extend the service life of the equipment largely.
2) Good thermal stability and excellent corrosion resistance
-50-350 ℃ is ideal temperature for the ceramic lined pipe, and the inner wall of the pipe is alumina ceramic tiles which have unique chemical properties of wonderful acid and alkali resistance.
3) Light Weight
The density is 3.63g/cm³, which is only half of the steel to reduce the load of equipment largely.
4) Easy and fast to fix on site
Welding, flange, flexible joint are available for fix with the equipment. All the performance of the High alumina ceramic lined elbow pipe / lining bend for wear solution makes low project costs, the charges can be about 20-30% less than wear steel piping project.
Application:
Alumina ceramic tile / tube lined steel tee tube / pipe for high wear area are widely used for serious abrasive environments, such as chute liners, cyclone liners, conveyor skirt liners, processing piping liners, hopper or silo liners, screen equipment liners in the industries including but not limited to:
♦ Coal Preparation Plants ♦ Coal Fired Power Stations
♦ Mineral Processing Plants ♦ Cement Plants
♦ Chemical Plants ♦ Steel & Iron Plants
♦ Railway Stations ♦ Ports
