  • galvanized steel pipe is a kind of pipe that the surface be covered by zinc .1. the hot dipped galvanized steel pipe;2. the pre galvanized steel pipe;3 cold galvanized steel pipe.

  • Hot dip galvanizing processing galvanizing also called hot dip galvanized and hot dip galvanizing: is an effective way of metal corrosion, mainly used for the metal structures and facilities.Will rust of steel parts are immersed into around 500 DEG C melting liquid zinc, steel pieces attached to the surface of the zinc layer, so as to prevent corrosion. Hot dip galvanizing process: refined picklin...

  • Manufacturers galvanize steel pipes by hot-dipping them by submerging the pipes in a bath of liquid zinc. This method is used because it gives a thicker layer of zinc over the base metal of the pipe. The hot-dip method is the most common method used for pipes, though there are other methods that can be used if a thinner coating of the zinc is needed, like electro-galvanization.The zinc protects th...
