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
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.
square pipe
20*20mm;25*25mm;30*30mm;40*40mm,50*50mm;60*60mm;75*75mm;80*80mm;90*90mm;100*100mm;120*120mm;127*127mm.
rectangular pipe
13*26mm;20*40mm;25*50mm;30*60mm;40*80mm;50*100mm;60*120mm;70*140mm;80*160mm;50.8*101.6mm
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.
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 .
- For gas and water service
- For general structure purpose
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kettle and then be withdrawn to inner-blowing station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.
