- From the production process, it can be seen that the inside of the ceramic wear-resistant composite pipe is an alumina ceramic pipe, and the outside is a steel pipe, so it can give full play to the advantages of steel pipes and ceramics: high strength, good toughness, impact resistance, and good welding performance The steel jade ceramic has high hardness, high wear resistance, corrosion resistance and good heat resistance, which fills the weaknesses of low hardness, poor wear resistance and poor ceramic toughness of the steel pipe.
- Observe the appearance: the wall thickness of the wear-resistant pipe with good quality is uniform and without deviation, the inner surface ceramic layer is smooth and smooth, and there is no gap between the ceramic layer and the steel pipe.
The good quality ceramic wear-resistant composite pipe is uniform in composition and looks very regular on the cutting head. It is also a smooth feeling to touch, not a burr. So if it is inferior material, the cutting head is uneven, and all the steel pipes look dull.
- There is also a poor quality ceramic wear-resistant composite pipe whose cross-section is not circular, may be oval or may be other shapes, this is because the manufacturer cut corners, resulting in non-compliance with the external dimensions. There is also the appearance of scarring, which is not allowed on high-quality wear-resistant ceramic composite pipes, but it is easy to see this phenomenon on residual wear-resistant ceramic composite pipes.
