Fluid pipeline transportation is widely used in thermal power, metallurgy, coal, petroleum, chemical, building materials, machinery and other industries. When transporting abrasive materials in the pipeline (such as ash, coal powder, slag powder, tailings cement, etc.), there is a problem of rapid wear of the pipeline, especially the rapid wear of the elbow; when the pipeline is transported When there is a strong corrosive gas, liquid or solid, there is a problem that the pipeline is corroded and quickly destroyed; when the material with a higher temperature is transported in the pipeline, there is a problem that the use of heat-resistant steel pipe is very expensive. With the use of ceramic-lined elbows, these problems have been solved.
Ceramic-lined elbows are also called wear-resistant ceramic lined elbows in the industry, because they organically combine the high hardness, high wear resistance, and corrosion resistance of ceramics with the workability, weldability, and high strength of steel. Therefore, the ceramic-lined elbow has the characteristics of good wear resistance, high temperature resistance, erosion resistance, and low running resistance. It is widely used in electric power, metallurgy, and chemical industry, cement, building materials, steel and other industries.
The ceramic lined elbow produced by Kingcera. In practice, the ceramic elbow is opened for observation and measurement after 1-2 years of use. The composite layer has no obvious wear or shedding. In terms of pipes of the same specification and unit length, The weight of ceramic-lined elbows is only about 1/2 of wear-resistant cast steel pipes or bimetal composite pipes, and its engineering cost per meter is reduced by 30-40%; compared with cast stone pipes and rare earth wear-resistant steel pipes, the weight is only 2 About /5, the project cost per meter is reduced by more than 20%. The price of wear-resistant ceramic elbows used in corrosive or high-temperature places is only a fraction of that of stainless steel pipes and nickel-titanium pipes.
