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. It is an ideal wear-resistant and corrosion-resistant pipeline for conveying granular materials, grinding, corrosive media, etc. It is widely used in wear-resistant industries such as electricity, mining, steel, cement, and chemical industry.

[0003] For example, the utility model patent with patent number 201921086912.X discloses a ceramic lined wear-resistant pipe with a special structure, which can be fixedly connected and used through the flange end plate at the end. The fixation of the rubber ring improves the fitting and sealing of the device. The casing has high strength, good toughness, impact resistance and welding performance. The ceramic lined pipe has high hardness, high wear resistance, corrosion resistance and good heat resistance. The lining end pipe is independently manufactured with high precision.
