1. Pipelines that require high wear resistance: thermal power generation, ash (slag) transportation in thermal power plants, coal powder transportation pipelines, tailings transportation and concentrate transportation pipelines in mineral processing plants, port slurry and sediment transportation pipelines, coal powder slurry transportation pipelines, etc.
2. For the transportation pipeline of clean coal in heavy medium selection (washing) coal plants, high corrosion resistance is required for the transportation pipeline of desulfurization slurry for thermal power generation.
3. Molten aluminum liquid transportation pipeline.
4. Various processes that require high wear resistance, high corrosion resistance, and high temperature resistance.
   The market for various applications of ceramic lined composite steel pipes

Power industry
① At present, China's power industry is in a period of rapid development. The country's newly installed capacity is 15 million kilowatts per year, of which about 12 million kilowatts are thermal power units, and thermal power generation is still the main source. Due to national environmental requirements, the ash and slag from coal powder combustion in thermal power plants need to be transported to a dedicated ash yard outside the plant area, with a transportation distance generally within 3-10 kilometers.
② The elbows of coal injection and slag discharge pipelines in thermal power plants and thermal power plants are severely worn parts. Currently, most of them use cast steel and cast stone pipes, which generally require major repairs and replacements after 2-3 years of use. Each steam furnace with a capacity of 300000 kilowatts requires 40-60 tons of elbows. If old power plants are included for major repairs and replacements, at least 500 companies in the country need to undergo major repairs and replacements. Every year, the electrical system alone requires over 10000 tons of wear-resistant elbows. In addition, the estimated annual demand for direct pipelines is also between 3000-4000 tons.

Metallurgical and mining industry
Among the unemployed in metallurgical mines, it is mainly used for the transportation pipelines of tail (independent) mines such as Panzhihua, Daye, Taihe Three Mines, Inner Mongolia Bailun Ebo and other mines. Due to high-strength wear and tear of the pipelines, they need to be repaired and replaced within one or two years. It is understood that the annual consumption of each mine is over 40 tons, and there are more than 20000 mines of various sizes in China, with an annual demand for wear-resistant pipes of approximately 500000 tons or more. In addition, the coal industry and other types of mines have not conducted detailed investigations, and it is estimated that their usage is also considerable.
