Hot dipped galvanized line for pipe

Introduction of the hot-dip galvanizing

Hot-dip galvanizing is a form of galvanization. It is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements.

The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. Galvanized Pipes & Tubes has long been one of the most used building materials in the world. For decades, designers, builders & consumers seeking long term structural performance, in the tuff outdoor applications, have turned to zinc coated steel pipes. Galvanized Pipes resist the attack of wild, water & road salts. Galvanized Steel if the one, that's been covered with a layer of zinc metal. During galvanizing, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Zinc's natural corrosion resistance provides long-term protection, even in outdoor environments. Apart from preventing water corrosion, it is equally effective in dry & indoor environment.
