Description

Technical Field

[0002] The full name of wear-resistant ceramic pipe is metal ceramic lined composite pipe. Wear-resistant ceramic pipe is manufactured by high-tech production process - self-propagating high temperature clutch synthesis method. The pipe is composed of three layers from inside to outside, namely corundum ceramic, transition layer and steel. The ceramic layer is formed by dense corundum porcelain at a high temperature above 2200℃, and forms a firm bond with the steel pipe through the transition layer. The composite pipe fully utilizes the high strength, good toughness, impact resistance, good welding performance of the steel pipe and the high hardness, high wear resistance, corrosion resistance and good heat resistance of the corundum porcelain, overcoming the characteristics of low hardness, poor wear resistance of the steel pipe and poor toughness of the ceramic. Therefore, the composite pipe has good comprehensive properties such as good wear resistance, heat resistance, corrosion resistance, resistance to mechanical shock and thermal shock, and good weldability.

[0003] Currently, wear-resistant ceramic tubes are generally installed by flanges or welding. However, wear-resistant ceramic tubes sometimes need to be docked with other pipe bodies during installation. Due to different sizes of flanges, they cannot be used and temporary welding is required, which reduces the installation efficiency.
