Abrasion has always been a factor that influences the safety of the civilized production. With the development of science, technology and the continuous innovation of materials, alumina ceramic linings is one of wear resistant linings which occupy 80% market share and has been most widely used in the world, featured by high hardness, good corrosion resistance and abrasion resistance, as well as high temperature resistance. It can be divided in to the following:
Product | 92 | 95 |
Al2O3% | ≥92 | ≥95 |
Fe2O3% | ≤0.2 | ≤0.15 |
Mohs' hardness | 8 | 9 |
Water Absorption (%) | ≤0.02 | |
Bulk Density(g/cm3) | ≥3.60 | ≥3.65 |
Abrasion(%) | ≤0.02 | |
Pipe linings of alumina ceramic cylinders have the following advantages:
Cold isostatic pressing makes long lifetime.
Maintenance-free operation makes no operation interruption and production losses.
Good corrosion resistance to strong sour and alkali
Smooth surface to achieve good flowability and to avoid plugs.
Application:
Flyash pipework lined with alumina ceramic tubes
Pulverized coal pipework lined with alumina ceramic pipes
