The advantage of ceramic sleeve lined pipe

Ceramic sleeve lined pipes is a type of piping component that has an outer steel shell and an inner ceramic sleeve. The ceramic sleeve is typically made of alumina ceramic or silicon carbide, which provides excellent resistance to wear and abrasion caused by high-velocity fluids, slurries, and abrasive media.

The advantages of using ceramic sleeve lined pipes include

1. Exceptional wear resistance: The ceramic sleeve lining provides excellent resistance against wear and abrasion, making it suitable for use in harsh and abrasive environments.
2. Corrosion resistance: The ceramic material used for the lining is highly resistant to corrosion from chemicals and other corrosive materials, increasing the lifespan of the entire piping system.
3. High-temperature resistance: Ceramic sleeve lined pipes can withstand high temperatures without losing their mechanical properties, making them suitable for use in high-temperature applications.
4. Reduced friction: The smooth surface of the ceramic sleeve lining reduces friction and turbulence, resulting in reduced pressure loss and increased flow rates.
5. Improved safety and reliability: Ceramic sleeve lined pipes can reduce the likelihood of equipment failure, enhancing the safety and reliability of industrial operations.
6. Customizable: Ceramic sleeve lined pipes can be customized to meet specific size and shape requirements based on the needs of the application.
7. Cost-effective: Ceramic sleeve lined pipes have a longer service life compared to traditional piping systems, reducing maintenance costs and downtime.

Overall, ceramic sleeve lined pipes are an excellent solution for industries that require reliable and durable piping systems for transporting abrasive fluids and slurries. Their high wear resistance, corrosion resistance, and long lifespan make them a cost-effective alternative to traditional piping materials.

The integrated moulding method (RHS) uses selected alumina particles to fire the inner liner pipe by various moulding methods, and then casts the integrally formed pipe inside the steel pipe with a special filler. The pipe formed by this method is different from the ceramic composite pipe formed by the self-grown combustion technology.

The utility model has the advantages that the inner wall of the pipeline is smooth and has good wear resistance, and is suitable for the slag and ash removal system with high requirements on the material of the pipeline, but the cost is high.

The coal will bring great impact to the equipment during transportation in the coal handling system of power station, so the alumina ceramic tiles is not available and they will fall off by large area. The valve in the desulfurization system can change the follow during the switching process, so the 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 integrated pipes which resist abrasion and corrosion are developed to well solve the problems of abrasion.

Because the lined ceramic tube is one piece, the slurry couldn’t permeate through it, moreover, the ceramic tube has high hardness and the process by isostatic pressing dry powder is favorable to the uniformity of ceramic crystal structure, so the its wear resistance is better than ceramic tile’s with the same material.

The weakest place is the gap between each sticked tiles during material handling. 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 is at least 5 times longer than ceramic tiles of the same thickness.
