First From the production process, it can be seen that the interior of the wear-resistant ceramic composite pipe is an alumina ceramic pipe, and the exterior is a steel pipe, so it can give full play to the advantages of steel pipe and ceramics: steel pipe has high strength, good toughness, impact resistance, and good welding performance. , Corundum ceramics have high hardness, high wear resistance, corrosion resistance, and good heat resistance, which fills the weaknesses of steel pipes with low hardness, poor wear resistance, and poor toughness of ceramics.

Second You can observe the appearance: the wall thickness of the good-quality wear-resistant pipe is uniform without deviation, the ceramic layer on the inner surface is smooth and uneven, and there is no gap between the ceramic layer and the steel pipe. This is a superior product.

Good-quality wear-resistant ceramic composite pipes are uniform in composition, look very regular on the cutting head, and feel smooth to the touch instead of burrs. Therefore, if it is a defective material, it will be uneven on the cutting head, and the entire steel pipe will look dull. If it is a fake and inferior wear-resistant ceramic composite pipe.

Third. There is also the fact that the cross-section of the fake and inferior wear-resistant ceramic composite pipe is not circular, may be oval or other shapes, this is the result of manufacturers saving materials and cutting corners, so this is not suitable Specification of external dimensions. There is also the appearance of scarring, which is not allowed to appear on high-quality wear-resistant ceramic composite pipes, but it is easy to see this phenomenon on inferior wear-resistant ceramic composite pipes.
