Product Description
The lining of alumina ceramic for coal powder conveying pipeline is a kind of lining pipeline designed for high wear and high corrosion conditions. It uses high-performance alumina ceramic material as the lining and is supported by steel pipes on the outside. Its unique structural design enables it to show excellent wear resistance and corrosion resistance in coal powder conveying, mining, power, and other industries.
Uses
Coal powder transportation: used in coal powder transportation systems in power plants, cement plants, etc. to reduce pipeline wear.
Mining industry: used to transport highly abrasive media such as slurry and tailings.
Chemical industry: used for pipelines for corrosive media.
Metallurgical industry: used for the transportation of high-temperature dust and granular materials.
Application
Power industry: coal powder conveying pipelines, coal mill outlet pipelines.
Cement industry: raw material and clinker conveying pipelines.
Mining industry: slurry and tailings conveying pipelines.
Chemical industry: corrosive medium conveying pipelines.
Metallurgical industry: high-temperature dust and granular material conveying pipelines.

FAQ
Q: How high a temperature can ceramic pipes withstand?
A: Alumina ceramic pipes can withstand 1200℃, and silicon carbide ceramic pipes can withstand 1600℃.
Q: How smooth is the inner wall of the ceramic pipe?
A: The inner wall smoothness Ra≤0.4μm, which significantly reduces the transportation resistance.
Q: How long is the service life of the ceramic pipe?
A: Under the condition of coal powder transportation, the service life can reach more than 10 years, which is 10 times that of ordinary steel pipes.
Q: How to install ceramic pipes?
A: Flange connection, welding, or quick connector can be used, which is easy to install and supports on-site cutting.
Q: Is the ceramic pipe easy to break?
A: The ceramic lining has a high-toughness design, and the external steel pipe provides support and excellent impact resistance.
Q: Does it support non-standard customization?
A: It supports customization of pipe diameter, length, ceramic thickness, and other parameters according to customer needs.
