Hot Dipped Galvanized Steel Pipe

Hot-dip galvanized steel pipes are first pickled on the steel parts. In order to remove iron oxide on the surface of steel parts, after pickling, they should be cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Hot-dip galvanized steel pipe is to make the molten metal react with the iron matrix to form an alloy layer, so that the matrix and the coating are combined. The zinc layer of hot-dip galvanized steel pipe is relatively thick, with a thickness of more than 10um. Although the surface is shiny, it is relatively rough and sequins will appear.

    Introduction

    Hot dip galvanized steel pipe (HDG) has been dipped in a protective galvanized or zinc coating to prevent corrosion and rust. Also, there are mainly three shades; yellow for BS-S, blue for BS-M, red for BS-H, and green for special types.
    Hot-dip galvanized pipe is galvanized on round steel pipe. It starts with hot-rolled coils, which go through a process of slitting, forming tubes, and dipping into a galvanizing bath consisting of at least 98.5% pure molten zinc. The bath temperature was maintained at about 450°C. In general, the thickness of the galvanized layer is at least 320 gm/m² and will increase according to the thickness of the metal (Base Metal)
    The specifications of the hot-dip galvanized steel pipe are atmospheric corrosion resistance and rust prevention, electrochemical and physical protection. This steel pipe is widely used in a variety of applications requiring advanced corrosion protection, such as outdoor offshore, irrigation piping, water mains, and power applications. In addition, it can be used for flower pot hangers in nurseries and structural molding works that require high durability, easy installation, and protection from steel corrosion.
