Hot dipped galv.seamless steel pipes advantage

The hot dip galvanized seamless steel pipe has marvelous corrosion resistance because of its galvanized coating. By making molten metal react with the substrate to create an alloy layer, the product offers secure bonding between the coating and the substrate, and the coating thickness is uniform as well. 

Hot dipped galv.seamless steel pipes application

water, gas, and oil conveyance
petroleum, chemical
construction industries to be used as the oil well pipe, the petroleum pipeline, the supporting bracket for trestles and underground tunnels, as well the pipeline for oil heaters, 
cooling systems, and so on.
Therefore, hot dip galvanized seamless steel pipes can be used in industrial, agricultural, and oceanic climate conditions, and its service life increases with the increase of the zinc coating thickness.

Manufacturing processes:

Firstly, the seamless tube undergoes acid washing so as to remove the iron oxides. Then, the product is washed in the aqueous solutions of ammonium chloride, or zinc chloride, or the mixed aqueous solution of ammonium chloride and zinc chloride. Finally, it is sent to the hot dipping tank to be galvanized.
