Hot dip galvanized pipe is first to acid wash the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after acid washing, through ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride mixed solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Hot rolled plates are hot rolled at high temperatures to remodel the internal structure of the steel, making the grain of the steel finer. But also can change the shortcomings of the steel structure, make the steel structure more strong and compact. Better ductility and load capacity.

The steel pipe made of hot or cold rolled steel plate or steel strip coil welding is called straight seam welded pipe on the welding equipment
More
Galvanized strip steel is cold rolled or hot rolled, long and narrow steel plate with different degrees of plating on a layer of raw materials called (zinc, aluminum). Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
