Galvanized Polygonal Steel Pipe
Pipe Parameters:
1. Side: Generally we can produce 8, 10, 12, 14, 16, 18, 20 with our bending machine.
2. Length of the pipe: Below 14 meters one time, we have our 3200ton Bending Machine, and it can bend 14 meters at one time, so below 14meters, we can do it.
3. Thickness of the pipe: Generally 6mm, 8mm, 10mm, 14mm, 18mm, 20mm, 25mm, and other according to your request.
4. Fabrication Process: Cutting plate(with our plasma flame cutting machine)→bending(with our 3200ton bending machine)→joint→welding(submerged-arc welding)
5. After all fabrication process, pipes are delivered to galvanization
Details of Galvanizing:
1. Degreasing of tower parts with Sodium Hydroxide solution.
2. Pickling to clean up the surface with HCl solution
3. Rinsing twice with fresh water to remove the acid content.
4. Fluxing with synth flux to prepare surface for galvanizing.
5. Drying on hot plate.
6. Dipping in zinc bath with 99.95% pure zinc at 450° C to 465° C temperature.
7. Quenching in water.
8. Dichromating.
Thickness< 5mm, galvanization thickness≥ 460G/M² (65um)
Thickness> 5mm, galvanization thickness≥ 610G/M² (86um)
All our galvanizing zinc thickness is strictly tested before delivery in view of its importance for anticorrosion.
