The automatic coating process of steel pipe anti-corrosion

Steel pipe anti-corrosion coating process 1: Adopt the curtain coating method, before coating, after coating, and in the middle of the roller conveyor, to form a coating film. Then the shift fork is transferred, the hook-shaped chain is rolled and conveyed, and the steel pipe enters the steam oven horizontally, and is heated and dried.

Steel pipe anti-corrosion coating process 2: Using the electrostatic coating method, the application of inclined roller conveyor before, after, and in the middle of coating to form a coating film. Then the screw elevator are transferred and lifted to the material rack to cool down for natural drying

Steel pipe anti-corrosion coating process 3: the steel pipe is conveyed in a straight line, using a UV coating system, vacuum coating method, and airflow scouring to form a coating film. UV radiation cures the coating film immediately after coating. The characteristic is that the formation and curing of the coating film are completed between two rollers

Steel pipe anti-corrosion coating process 4: heating airless spraying method is used for coating, roller conveyor transportation is used before coating, and segmented synchronous "V-shaped tooth" chain transportation is used after coating to form a coating film. After coating, the steel pipe is transferred from the stepper to the horizontal "V-shaped tooth" chains conveyor and enters the steam drying box of heating and drying
