Abstract

The invention relates to a method for preparing a composite anticorrosion, wear-resistant, and high-temperature-resistant pipe, which comprises the following steps: 1) making porcelain tiles: according to the proportion, select raw material powders with a particle size of 50 μm, mix them evenly, and mix the evenly mixed The powder is made into a green body of ceramic chips, and then sintered at high temperature to make ceramic chips; 2) Making ceramic tubes: according to the size of the pipe diameter, select an appropriate number of ceramic chips and splice them into a circular ceramic ring. Bonding with a high temperature and corrosion resistant adhesive, and then bonding the ceramic ring with a high temperature and corrosion resistant adhesive to form a ceramic tube; 3) Prepare a composite tube: coat a layer of inorganic layer in the metal tube body, and When it is not solidified, insert the ceramic tube into the metal tube body to ensure the seamless bonding of the ceramic tube and the inorganic layer. After the inorganic layer is solidified, a composite anti-corrosion, wear-resistant, and high-temperature-resistant tube is produced. The invention can process the metal composite ceramic tube with good corrosion resistance, wear resistance, high temperature resistance and impact resistance, and the production process is simple and the cost is low.

Description

technical field [0001] The invention relates to the technical field of special pipes, in particular to a method for preparing a composite anti-corrosion, wear-resistant and high-temperature-resistant pipe. Background technique [0002] Special pipes are pipes used in special environments. Different from ordinary pipes, the use environment of special pipes determines that they need to have special properties, such as high temperature resistance, wear resistance, impact resistance, etc. For example, the tertiary air pipe of a cement kiln is a special pipe used in a cement kiln. When the cement kiln is running, the temperature inside the pipe changes greatly, the wind speed inside the pipe is high, and the hot air flow contains a large number of fine clinker particles. Scouring and erosion of dusty hot air. Another example is oil pipelines, which are used to transport crude oil and work under high pressure and corrosion conditions for a long time. These special scenarios requ...
