The selection of wear-resistant materials is crucial in pneumatic conveying systems, as they need to be able to withstand the impact, scratching, and wear of materials on pipelines. Here are some common wear-resistant materials for pneumatic conveying:

1. Ceramic wear-resistant materials

Ceramic lined wear-resistant pipe: The ceramic lined wear-resistant pipe improves the wear resistance of the pipeline by lining a layer of ceramic material on the inner wall of the steel pipe. Ceramic materials have excellent wear resistance and chemical stability, and can withstand the impact and scratching of particle materials, gases, or liquids on the inner wall of pipelines. At the same time, the ceramic surface is smooth and not prone to frictional resistance, which helps to improve conveying efficiency. In addition, ceramic materials also have good corrosion resistance and high temperature resistance, making them suitable for various harsh transportation environments.

Corundum ceramic wear-resistant tube: Corundum ceramic wear-resistant tube uses high hardness corundum ceramic as the lining material, which has extremely high wear resistance and corrosion resistance. This type of pipeline is particularly suitable for transporting abrasive media such as coal powder, slag, etc.

2. Metal wear-resistant materials

High chromium alloy wear-resistant pipe: The high chromium alloy wear-resistant pipe is made of Q235 ordinary outer steel pipe and high chromium alloy lining material, which has good wear resistance, heat resistance, and corrosion resistance. This pipeline can transport dry ash, gangue, coal powder and other media, and is easy to install, suitable for various pneumatic conveying occasions.

Bimetallic wear-resistant pipeline: Bimetallic wear-resistant pipeline combines the advantages of two or more metal materials and is made through special processes. This type of pipeline has high hardness and wear resistance, making it suitable for pneumatic conveying systems that require high wear resistance.

3. Other wear-resistant materials

Rare earth alloy wear-resistant pipeline: Rare earth alloy wear-resistant pipeline utilizes the special properties of rare earth elements to improve the wear resistance and corrosion resistance of the pipeline. This type of pipeline has good application effects in some special working conditions.

Self propagating combustion bonded ceramic wear-resistant pipe: This pipe is cast as a whole by centrifugal casting and made of aluminum oxide material. It has good wear resistance, can withstand high temperatures, and is lightweight, making it easy to transport and install. Especially suitable for the pneumatic conveying industry.
