Alumina Ceramic Lined Elbow
Product Description
Alumina ceramic lined elbow is an ideal pipeline for conveying granular materials, grinding and corrosive media. The elbows are installed onto the internal surface of the pipe properly by welding, pasting or inter-locking system. Due to its superior mechanical and thermal characteristics it can withstand heavy erosion and corrosion. Alumina Ceramic liners are the perfect solution when there is need to reduce or eliminate erratic material flow challenges. Alumina ceramic lined elbow is widely used in oil, electric power, metallurgy, mine, etc.
Advantages
Alumina ceramic lined elbow is an ideal corrosion resistant pipeline. It has high temperature resistance, wear resistance, impact resistance, acid and alkali corrosion and easy construction. The leakage caused due to the abrasion can be avoided and enhance the service life. Alumina ceramic lined elbow can also be used in all parts of the concrete pump, which has the advantages of light weight and avoids the blockage in the process of concrete transportation.
Characteristic
Excellent wear resistance: not easy to wear and tear, strong durability
High hardness: 88-96.5 mosh
Good heat resistance: high mechanical strength, can be used in high temperature environment.

Details of alumina ceramic elbow
The coal will bring great impact to the equipment during transportation in the coal handing system of power station, so the alumina ceramic tiles s not available and they will fall of by large area.
The valve in the desulfurization system can change the follow during the switching process, sot he slurry with grain at high speed will wear out the pipe at the ends of valves. The liquid in the tube contains much sulfite which is very corrosive, so usually nonmetallic pipes like rubber tubes and PVC pipes are used to avoid corrosion, but the wear resistance of these tubes are poor that the straight pipe at the ends of valves always worn out. The alumina ceramic lined tube/elbow is one piece, the slurry couldn’t permeate through it, moreover, the alumina tube/elbow has high hardness and the process by isostatic pressing dry power is favorable to the uniformity of ceramic crystal structure, so its wear resistance is better than ceramic tiles with the same materials.
The weakest place is the gap between each sticked tiles during material handing. The material grains not only wear the pipe but also have impact on it. This is why the pipelines lined by tiles are easily worn out and fallen off.
The experiment shows that the service life of ceramic tube/elbow is at least 5 times longer than ceramic tiles of the same thickness.
