A continuous galvanized pipe painting production process and equipment. The process includes the following steps: passivation step, cleaning step; painting step; curing step. Before the painting step, there is a drying and preheating step, and the drying step The intervention heat temperature is the curing temperature of the exterior coating ±20°C. The equipment is based on the well-known equipment, and is equipped with a drying and preheating furnace in front of the dipping tank. The process and stamping equipment of the present invention can not only carry out continuous painting production of galvanized pipes in large quantities, but also ensure the quality of painting auto sheet metal parts, without bubbles and orange peel on the surface, and the work efficiency can be improved by twenty to thirty times.
