Galvanized pipe coating a continuous production process and equipment technology, including the following steps: Passivation steps, cleaning steps; Coating step; Curing step, the steps in the painting has dried before preheating step, and the dry warm temperature is applied externally coating the curing temperature of ± . The device is based on the public to know the equipment, drying in the dipping tank with preheat oven before. The technical process and equipment can not only large quantities of continuous galvanized pipe coating production, and to ensure the coating quality, surface bubbles can not afford, can not afford orange peel, ergonomics can increase two to three times.

Galvanized pipe outside
A simple, inexpensive external galvanized pipe. The utility of new technologies outside the galvanized pipe, including the tube wall and the pipe inner wall, outer wall of the tube above a layer of zinc coating to set. The utility of new technologies set the outer tube only zinc coating, saving resources can significantly reduce costs; The utility of new technologies can be used to produce a variety of water pipeline, gas pipeline or other pipeline accessories.

Reason
Zinc chemical lively higher than iron, electrochemical corrosion occurs, the first corrosion is zinc rather than iron, zinc oxide and relatively compact, can prevent further oxidation. So, usually galvanized steel has good corrosion resistance.

To improve the corrosion resistance of steel pipe, steel pipe for general galvanizing. Galvanized and hot galvanized steel galvanized sub-two, hot dip galvanized zinc thickness, galvanized, low cost, not a very smooth surface. Oxygen blowing pipe: Used for blowing oxygen steel pipe, generally with small diameter welded steel pipe, size eight by the 3/8-2 inch. With 08, 10, 15, 20 or 195-Q235 of steel produced, in order to prevent corrosion, something to be aluminized.
