Galvanized Steel Pipe

Introduction:

Galvanized steel pipe usually means the hot-dip galvanized steel pipe. To make the hot-dip galvanizing pipe, firstly do the pickling in order to remove the iron oxide on the surface of the steel pipe, then clean the pipes in the ammonium chloride or zinc chloride aqueous solution, and then put the pipes into Hot-dip galvanized bath, the galvanized layer can improve the corrosion resistance of steel pipe so as to extend the service life. Galvanized steel pipe is not only widely used in the field of water, gas, oil and other general low-pressure fluid pipeline, but also in chemical coking equipment such as oil heater, condensation Cooler, and the bridge piles such as mine tunnel support tube and so on.
