The large diameter ceramic patch composite pipe is composed of an outer steel pipe and an inner lining ceramic sheet. The lining ceramic sheet is made by hand. The ceramic pipe specification is lower than DN150. It is not recommended to use a ceramic patch pipe. Ring replacement, larger than DN150 specifications, such as DN200, DN250, DN300, DN350, DN400, etc., or even large-diameter DN1200, large diameter ceramic patch composite pipe If you need to choose the patch process, we can customize it according to customer needs.

Products Feature

Large diameter ceramic patch composite pipe lined with alumina ceramic sheet is a special corundum ceramic made of AL2O3 as the main raw material, rare metal oxide as a flux, and calcined at a high temperature of 1700 degrees. It is formed by dry pressing and isostatic pressing and fired at high temperatures. The Rockwell hardness is HRA88, which has the characteristics of wear resistance, impact resistance, and convenient construction, which can effectively prolong the service life of various equipment. Common specifications of alumina ceramic sheets: 10*10*3-10, 17.5*17.5*3-15, 20*20*4-20, and can also be customized according to customer requirements.

Product advantages

Wear resistance: The Al2O3 content in the ceramic lining layer of the wear-resistant ceramic tube is between 92% and 99%, and its wear resistance is ten times higher than that of the quenched medium carbon steel, which is better than tungsten carbide.

Corrosion resistance: the ceramic of the wear-resistant ceramic tube is a neutral material with stable chemical properties

Easy to weld: wear-resistant ceramic pipes can be connected by welding outer steel pipes.

Convenient transportation and installation: relatively light in weight, easy to transport and install.
