Intragalvanization is a technical term used in the field of corrosion engineering. IPA phonetic transcription of intragalvanization is ˈɪn.trə.ˌɡæl.və.naɪˈzeɪ.ʃən. The word consists of three syllables: in, tra, and galvanization. The stress is on the third syllable, pronounced as /ˌɡæl.və.naɪˈzeɪ.ʃən/. The prefix "intra-" means within, while "galvanization" refers to the process of coating a metal with zinc to protect against corrosion. Therefore, intragalvanization signifies the process of applying a zinc coating within a structure to prevent internal corrosion.
Intragalvanization refers to the process of applying a protective coating or layer of zinc to the inner surfaces of hollow structures, such as pipes, tubes, or tanks, through a galvanizing process. Galvanization, in general, is the act of coating a metal or alloy with a layer of zinc to protect it from corrosion and rust formation. However, traditional galvanization primarily focuses on coating the external surfaces of objects, whereas intragalvanization focuses specifically on the internal surfaces.
The process of intragalvanization involves immersing the hollow object into a bath of molten zinc or applying a zinc-rich paint to the inner surfaces. The zinc coating acts as a sacrificial barrier, providing cathodic protection by oxidizing instead of the underlying metal, thereby preventing corrosion. Not only does intragalvanization enhance the overall longevity and durability of the structure, but it also helps maintain the flow of liquids or gases within the hollow object by reducing friction and minimizing the risk of blockages caused by corrosion or scaling.
Intragalvanization finds its applications in various industries, including water supply systems, oil and gas pipelines, automotive manufacturing, and construction. By ensuring complete protection of both the inner and outer surfaces of hollow structures, intragalvanization plays a crucial role in preserving their structural integrity and extending their lifespan, even in harsh environments or corrosive conditions.
