A continuous galvanized pipe painting production process and equipment, the process includes the following steps: a passivation step, a cleaning step; a painting step; a curing step, a drying preheating step is provided before the painting step, and The intervention heat temperature is the curing temperature of the outer coating, which is 20℃.
The equipment is based on the well-known equipment, and there is a drying preheating furnace in front of the dip coating tank. The process and equipment of the invention can not only perform continuous galvanized tube painting production in large quantities, but also ensure the quality of painting, no bubbles on the surface, no orange peel, and the work efficiency can be increased by two to thirty times.
