AI Technical Summary

Technical Problem

Existing shot blasting processes can easily damage the zinc layer when treating the surface of galvanized steel pipes, leading to a reduction in the corrosion resistance and service life of the galvanized steel pipes.

Method used

The system employs a positioning mechanism, a feeding mechanism, and a surface treatment mechanism. It uses first and second grinding wheels to finely grind the surface of the galvanized steel pipe to form a textured structure. Combined with a lifting mechanism, it avoids over-grinding. A guide component is used to achieve automated movement, adapting to steel pipes of different outer diameters.

Benefits of technology

It improves the smoothness of the galvanized steel pipe surface and the adhesion of protective materials, enhances corrosion resistance and service life, while also improving processing efficiency and reducing the difficulty of manual operation.
