Ultrafine ceramic and metal composite pipe and preparation method thereof

Abstract

The invention relates to an ultrafine ceramic and metal composite pipe which comprises a metal pipe body, wherein the diameter of the metal pipe body is less than 10 cm; a ceramic pipe is arranged inthe metal pipe body in a sleeving manner; the ceramic pipe is fixed with the metal pipe body through an inorganic layer; the ceramic pipe is formed through splicing multiple tiles; and every two adjacent tiles are glued and fixed through a high temperature and corrosion resistant adhesive. The invention further provides a preparation method of the ultrafine ceramic and metal composite pipe. The preparation method comprises the following steps: 1, manufacturing tiles; 2, manufacturing a ceramic pipe; and 3, manufacturing the composite pipe. The ceramic pipe manufactured in the step 2 is inserted in the metal pipe body to ensure seamless gluing of the ceramic pipe and the inorganic layer, and after the inorganic layer is solidified, the ultrafine ceramic and metal composite pipe is manufactured. The ultrafine ceramic and metal composite pipe can resist corrosion, wear and high temperature, is high in shock resistance, and is simple in producing process and low in cost.

Description

Technical field [0001] The invention relates to the technical field of special pipes, in particular to an ultra-fine ceramic and metal composite pipe and a preparation method thereof. Background technique [0002] Special pipes are pipes used in special environments. Unlike ordinary pipes, the use environment of special pipes determines that they need to have special properties such as high temperature resistance, wear resistance, and impact resistance. For example, the tertiary air duct of a cement kiln is a special type of pipe used in cement kilns. When the cement kiln is running, the internal temperature of the pipe changes greatly, the wind speed in the pipe is relatively high, and the hot airflow contains a large number of small clinker particles. Erosion and erosion of dusty hot air currents. Another example is oil pipelines, which are used to transport crude oil and work under high pressure and corrosive conditions for a long time. These special scenes all require speci...

AI Technical Summary

Problems solved by technology

However, the preparation process of the existing ceramic composite pipe is complicated, the processing of the ceramic pipe is difficult, and the cost is extremely high

Secondly, the existing ceramic composite pipes have poor impact resistance, the inner ceramic wall is easy to break, damage and fall off, and the service life is short

Finally, the current ceramic composite pipes generally have large diameters, and composite pipes with diameters below 10 cm are extremely difficult to produce, and composite pipes with diameters below 5 cm cannot be produced, and ultra-long seamless composite pipes cannot be produced at present.
