Description

Steel pipe immersion cleaning line

technical field

The invention belongs to the technical field of steel pipe processing, and in particular relates to a steel pipe immersion type cleaning line.

Background technique

Powder spraying is to use powder spraying equipment (electrostatic spraying machine) to spray powder coating on the surface of the workpiece.
