Electro-galvanizing(EG):it is to remove the oil, pickle, and then put into the solution of zinc salt by electrolysis equipment,
and connect the negative electrode of the electrolysis equipment, place the zinc plate on the opposite side of the pipe fitting,
and connect When the positive electrode of the electrolysis device is turned on, a layer of zinc is deposited on the pipe by the
directional movement of the current from the positive electrode to the negative electrode, and the cold-plated pipe member is
processed and then galvanized.
