Clean and economical Hot Dip Galvanizing Equipment 

Carefully designed zinc dust collecting system can reduce zinc consumption and help to improve operation safety of the dust filter.

• Main Technical specification 

• Applicable pipe size 

Nominal bore: Min. 1/2” – Max. 6” 

Wall thickness: Min. 1.5mm – Max. 4.5 mm 

Pipe length:5-6m(1/2”,3/4”) 4-6m(1”-6”) 

Some kinds of squire and rectangular pipes can be treated by this line. But the line should be restricted within 2 pipes , the ratio of long and short side should be restricted within 1.5 and the min. bore dimension of pipe must be larger than 25mm.

• Galvanizing Method. 

Dry type galvanizing system；

Pipe OD under 1-1/2”(including 1-1/2”) are processed with quadruple line way;

Pipe OD 2”-4” (including 4”) are processed with double line way.

Pipe OD 5”and 6” are processed with single line way.

• Wiping of excess zinc 

Outside of pipe: By Compressed Air with outer blowing

Inside of pipe: Pipe OD 1/2”and 3/4” By Over-heated Steam inner blowing nozzle.

For pipe’s OD above 1”(including 1”) lancer plug inner blowing technique is adopted for improving the inner coating quality ,saving steam consumption and lessening the generation of zinc powder .

• Product Usage 

• For gas and water service 
• For general structure purpose 

• Standard 

This galvanizing plant is designed so that pipes can be dipped into kettle and then be withdrawn to inner-blowing station automatically.

Star wheel type dipping device is used for pipe dipping. It can help to adjust the dipping time flexibly by using different running program.

Long lancer plug inner blowing technology by using hot compressed air is used for pipe above 1”(including 1”) . The usage of this technology results in improvement on quality of inner blowing, saving steam consumption and reducing generation amount of zinc powder.
