Hot Dip Galvanized Steel Tube
/ Pipe
As the galvanization technology helps to enhance the corrosion resistance and prolong the life span of the tube, our HDG or hot dip galvanized steel tube or pipe is coated with the zinc layer. Apart from being used as the pipeline for transmitting the low pressure fluid like water, coal gas and oil, our product is also applied in petroleum industry, especially as oil well pipe, oil pipeline in the marine oil field. It is suitable for oil heater, condensate cooler, coal distillation wash oil exchanger in the chemical coking equipment, as well as trestle pile, support frame tube for mining tunnel, etc.
