Wear-resistant ceramic ash and pulverized coal pipelines are used to transport solid particulate materials such as ash and pulverized coal. The following describes their structure, features, and applications:

Structural Composition

Ceramic Lining: Typically made of Alumina ceramics, these materials offer excellent wear resistance. These ceramics possess high hardness, wear resistance, corrosion resistance, and heat resistance, with a Mohs hardness of approximately 9, effectively resisting the erosion and wear of materials such as ash and pulverized coal.

Transition Layer: Located between the ceramic lining and the outer steel pipe, this layer acts as a connector and buffer, ensuring a secure bond between the ceramic layer and the steel pipe and alleviating stress caused by the different thermal expansion coefficients between the two layers.

Outer Steel Pipe: Typically constructed of ordinary carbon steel or stainless steel, this layer provides strength and toughness, enabling it to withstand the pressure and external forces during transportation and facilitating installation and connection.

Performance and Characteristics

High Wear Resistance: The ceramic lining's high hardness makes its wear resistance several or even dozens of times greater than that of ordinary steel pipes. It effectively resists the erosion and wear of particles such as ash and pulverized coal, significantly extending the pipe's service life. Good Corrosion Resistance: Ceramic materials have excellent chemical stability and are resistant to corrosion from media such as acids and alkalis. They are also highly resistant to acids and other corrosive components that may be present in ash, ensuring the structural integrity of the pipe.

High-Temperature Resistance: They maintain stable performance in high-temperature environments and can withstand high temperatures without deformation, meeting the requirements of conveying pulverized coal, ash, and other materials at high temperatures.

Low Operating Resistance: The inner surface is smooth and rust-resistant, surpassing the smoothness of any metal pipe. The drag coefficient is 0.0193, slightly lower than that of seamless pipe, reducing operating costs.

Excellent Shock and Thermal Expansion Resistance: The viscose adhesive has a thermal expansion coefficient between that of steel and ceramic, effectively accommodating the impact of thermal expansion mismatches between steel and ceramic. Furthermore, the addition of various flexible fibers to the adhesive maximizes the ability of the ceramic to withstand long-term operation without dislodging in environments with vibration and frequent thermal expansion and contraction.

Easy Installation: The pipe is lightweight and has excellent weldability. It can be installed using welding, flanges, and quick-connects, making it easy to install and reducing installation costs. Applications

Power Industry: In thermal power generation, it can be used in pulverized coal conveying systems and ash discharge pipelines. It effectively resists erosion from pulverized coal and ash, reduces pipe wear and corrosion, and improves pipe wear resistance, ensuring stable power generation, reducing maintenance costs and downtime, and significantly improving power generation efficiency.

Metallurgical Industry: Suitable for high-temperature slurry conveying pipelines and conveying pipelines in ore crushing systems. It can withstand the erosion of large amounts of metal ions, solid particles, and corrosive media in high-temperature slurries, resisting the high-speed impact and friction of ore, extending pipeline service life and improving production efficiency.

Mining Industry: It can be used in slurry, tailings, and other conveying pipelines, resisting the wear of ore particles, reducing the frequency of pipe replacement, and lowering operating costs.
