Ceramic wear tube

- Aug 07, 2019-

The ceramic wear-resistant tube is a kind of ceramic composite steel pipe.

It adopts high-tech production process--manufactured by high-temperature clutch synthesis method.

Application

Because the tube has wear resistance, corrosion resistance and heat resistance, it can be widely used in electric power, metallurgy, mining, coal, chemical and other industries as conveying abrasive materials such as sand, stone, coal powder, ash and aluminum liquid. And corrosive media, is an ideal wear-resistant pipe.

1. Applications in metallurgy and power industry

The transportation of pulverized coal, ash, mud, lime gypsum slurry, etc. in the metallurgical and electric power industries requires a large amount of metal pipes to be consumed each year. The ceramic composite pipe is used to replace other pipes, and has the characteristics of high wear resistance, long service life, convenient installation and remarkable economic benefits. Its operating life is ten or even dozens of times that of steel pipes.

2. Application in mining and coal industry

(1) Mine: Mine filling, concentrate powder and tailings transportation cause serious wear on the pipeline, which can increase the service life by about 5 times.

(2) Coal: The coal transportation and long-distance pipeline coal transportation are generally carried out by wet method. The conveying pipe is required to be both wear-resistant and corrosion-resistant. The pipe can be used as a long-life conveying pipe with considerable economic benefits.

Process characteristics

Patch wear-resistant ceramic pipe: aluminum heat-centrifugation method is used to combine ceramic and metal organic, and aluminum heat-centrifugation method is used to prepare lining ceramic steel pipe. The reaction product is melted by high temperature generated by self-heating reaction and separated under centrifugal force. Forming a steel tube lined with alumina ceramics.

Self-propagating composite pipe: ceramic powder + iron oxide powder + magnesium oxide powder mixed in proportion (mainly iron oxide, black), seal the ends of the pipe, add powder, pipe rotation, electronic ignition, sintering in the pipeline by centrifugal method Inner wall.

Integral calcined ceramic pipe: According to the mold, the ceramic powder is sintered into a ceramic pipe and then combined with the steel pipe. The outer wall of the ceramic tube and the inner wall of the steel pipe are assembled by casting a special filler (cement or epoxy resin) inside the steel pipe, and then isostatically pressing.
