3PE winding operation line
Using the principle of electrostatic spraying, the tube body is heated to a certain temperature through a medium frequency heating chamber, and then enters the powder spraying chamber for surface spraying to form the required coating thickness; Then, use an extruder to extrude adhesive and wrap polyethylene onto the spiral advancing steel pipe.

Water Cooling System
The water cooling system uniformly and effectively cools the heated and sprayed steel pipes, ensuring that their temperature does not exceed 60 ° C when they are offline, increasing the amount of cooling water, and improving cooling efficiency. This system includes: water tank, water pump, pipelines and valves, and water tank.

Powder Spraying System
High performance circuit design enables an output voltage of up to 98KV, while the spray gun is equipped with three air intakes to ensure sufficient atomization of the coating. Reasonable spray gun layout greatly improves powder coating rate and ensures uniform coating thickness.
