Main Equipment

1. Enclosed pre-treatment equipment with acid proof tanks 
○ Latest materials and technology for environmental protection 
○ Acid resistance treatment for the full construction 
○ Controlled air flow to maintain negative internal pressure 
○ System designed to work automatically with the scrubber. 
○ Hoists with he workpiece run according to the process inside the enclosure. 

2. Drying equipment
○ Reduce the happenings of zinc blast, and less zinc consumption
○ By making full use of the recycled heat, the workpieces get the proper temperature before dipping into the zinc kettle, less dipping time is needed, the capacity efficiency is increased.
○ Heat circulation blower is adopted, it gives even temperature inside the drying furnace.

3. Heating furnace
○ World-class technology in heat transfer design in the furnace, widely used in more than 200 projects 
○ Good insulation and fuel saving. 
○ Uniform temperature inside the furnace. Even heating of the zinc kettle is key to extend the zinc kettle lifetime. 
○ Quick response to the temperature control, high efficiency and economical operation.
○ The kettle change is simply and convenient, low furnace maintenance cost.

4. Zinc kettle
○ The kettle plate is made specially for liquid zinc, low carbon and silicon, corrosion proof 
○ Professional welding skills, the lifetime of the welding seam is longer than the mother steel plate
○ Various zinc kettle geometric structures, different steel plate thickness, accurate dimensions.

5. Gear Disk Type Galvanizing Machine
○ With different disk tooth numbers and gear changing, the galvanizing coating thickness can be controlled flexibly.
○ A single galvanizing machine can produce a wide range of pipe diameter and length.
○ High degree of automation and convenient operation.

6. Draw-out and Draw-up equipment
○ Big magnetic force from the magnetic rolls, it ensures the smooth pick up of the pipe out of the zinc kettle.
○ Several pipes are galvanized simultaneously, stable pipe separation treatment, long time continuous running smoothly.
○ Well designed roller arrangement, smooth roller surface, even rotation speed, good pipe appearance quality is achieved.

7. Inner blow equipment
○ Guiding rod inner blow is adopted, very clean and smooth inner pipe surface, liquid zinc inside the pipes are recovered back to the zinc kettle, high utilization efficiency of zinc, less zinc dust, and lower blowing noise.
○ Electro-magnetic obsorbing clamping is adopted, this technology can decrease the damage to the galvanized surface.
○ Inner blow for one single pipe available, as well for multiple pipes simultaneously.

8. Water cooling equipment
○ Automatic equipment conveying pipes into the water in order
○ Automatic pipe discharge equipment out of water.

9. Color belt and logo marking equipment
○ Alternative color belt painting equipment for option. Printer with magnetic color belt frame can paint 1 pipe a time, no limitation of the pipe diameter.   Point topping printer is suitable for multiple pipes a time of smaller pipe diameter.
○ Satisfying the demands of single color of single belt and multiple colors of multiple belts 
○ Options with spray printing and roller marking 
○ Clear marking, adjustable content , and convenient operation. 

10. Passivation equipment
○ Automatic passivation equipment, the passivation chemical is recycled, safety and environmentally friendly.
○ Chain type drying is adopted after passivation, the passivation film is fasten and stable.

11. Automatic bundling and strapping equipment
○ Based on different workship size, special pipe conveying mode (vertical or horizontal) is designed.
○ Automatic bundling equipment can achieve different bundle shapes (square/hexagon/other shapes), intensity of labor is greatly decreased.

12. Zinc pump
○ Big flow capacity, long lifetime and easy operation.
