CN2252927Y - Ceramic Composite Tube - Google Patents

Abstract

The utility model discloses a ceramic composite pipe can regard as thermal power factory lime-ash conveying line, mine slay conveying line etc.. The utility model is characterized in that the outer layer 1 is a metal layer, the inner layer 2 is a ceramic layer, and the middle layer 3 is a filling layer. Because the pottery has wear-resisting corrosion-resistant advantage, therefore, this novel wear resistance that has is good, corrosion resisting property is high, long service life, use cost low grade advantage.

Description

Ceramic Composite Tube

The utility model relates to a ceramic composite pipe, which can be used as ash and slag conveying pipelines in thermal power plants, mine slag conveying pipes and the like.

At present, steel pipes are generally used in the ash and slag conveying pipelines of thermal power plants and mine slag conveying pipelines. Due to poor wear and corrosion resistance, it needs to be replaced frequently, usually once every 3-4 months. Therefore, the use cost is high.

The purpose of the utility model is to provide a wear-resistant and corrosion-resistant ceramic composite pipe. It does not need to be replaced frequently, has a long service life and low cost of use.

The purpose of this utility model can be achieved like this: it is a kind of ceramic composite pipe, and its outer layer 1 is a metal layer, and its inner layer 2 is a ceramic layer, and its middle layer 3 is a filling layer.

The filling layer of the above-mentioned ceramic composite pipe may be a cement mortar layer.

The filling layer of the above-mentioned ceramic composite pipe may be a cement layer.

Compared with the prior art, the utility model has the following advantages and practical effects: due to the composite layer structure, the outer layer 1 is a metal layer, which is convenient for transportation; the middle layer 3 is a filling layer, which can prevent the ceramic layer from falling off; The inner layer 2 is a ceramic layer, and ceramics have the advantages of wear resistance and corrosion resistance. Therefore, the utility model has the advantages of wear resistance and corrosion resistance. According to tests, its wear resistance is more than 20 times that of metal steel pipes.

The accompanying drawings and descriptions of the drawings are as follows:

The utility model will be described in further detail below in conjunction with the accompanying drawings:

Accompanying drawing 1 and accompanying drawing 2 have provided the embodiment of cylindrical ceramic composite pipe of the present utility model. Its outer layer 1 is a round metal steel tube, and its inner layer 2 is a round ceramic tube. The round ceramic tube can enter the round metal copper tube. There is a gap between the two, and the middle layer 3 is in this gap. The middle layer 3 is The filling layer can be a cement mortar filling layer or a cement filling layer. Cement mortar is used as the filling layer, and it must be filled when the cement mortar is wet, and it must be tightly filled. When cement mortar is wet, its volume is small; when it dries, its volume increases. Therefore, as long as the cement mortar is tightly filled when it is wet and the cement mortar is dry, the outer layer 1 and the inner layer 2 of the utility model can be tightly combined, and the ceramic layer is not easy to fall off. Clay is used as a filling layer, and it must be filled tightly when the clay is wet. The clay filling layer not only sticks to the metal outer layer 1, but also sticks to the ceramic inner layer 2, and the ceramic layer is not easy to fall off.

Claims (3)

1. A ceramic composite pipe, characterized in that its outer layer (1) is a metal layer, its inner layer (2) is a ceramic layer, and its middle layer (3) is a filling layer. 2. The ceramic composite pipe according to claim 1, characterized in that said filling layer is a cement mortar filling layer. 3. The ceramic composite pipe according to claim 1, characterized in that said filling layer is a clay layer.
