Hot dipped galvanized pipes are an essential component in various industries, offering superior corrosion resistance and extended service life. This process involves a chemical reaction where molten metal interacts with the iron substrate to create an alloy layer, ensuring a robust bond between the substrate and the coating. In this article, we will explore the process of hot dipping, the benefits it provides, and the key parameters that define the quality of galvanization. The Process of Hot Dipping The hot dipping process starts with acid cleaning the steel pipes. This critical step removes the layer of iron oxide from the surface, preparing it for effective galvanization. After the acid pickling, the pipes undergo a washing operation in a solution that may include ammonium chloride, zinc chloride, or a combination of both. Once cleaned, the pipes are immersed in a hot dip galvanizing bath. During this immersion, a series of complex physical and chemical reactions occur between...
