Hot-dip galvanizing is a form of galvanizing. This is the process of applying a thin layer of zinc to iron or steel and passing the steel through a molten zinc bath at a temperature of approximately 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. This is a dark gray, fairly strong material that in many cases prevents further corrosion and protects the underlying steel from the influence of elements. The hot-dip galvanizing process uses a series of different iron-zinc alloys to form a metallurgical bond between zinc and steel. Galvanized pipe has long been one of the most widely used building materials in the world. For decades, designers, builders, and consumers seeking long-term structural performance for outdoor applications of tuff have turned to galvanized steel pipes. Galvanized pipe can resist the erosion of wild salt, water and road salt. If it is galvanized steel, it is covered with a layer of zinc metal. During the galvanizing process, the steel is immersed in a molten zinc bath to ensure the formation of a tough, uniform barrier coating. Zinc's natural anti-corrosion properties provide long-term protection, even in outdoor environments. In addition to preventing water corrosion, it is equally effective in dry and indoor environments.
Galvanized steel pipes are covered with a layer of zinc and are mainly used for structural applications. Various sizes and shapes can be provided according to customer requirements. Hot-dip galvanized steel pipes are formed by high-quality welded pipes and advanced galvanizing technology and equipment, with smooth inner and outer surfaces without black spots and bubbles. It has high corrosion resistance and is widely used in electrical pipelines under harsh conditions.
