Differences Between Hot-Dip Galvanized Pipe Fittings and Electro Galvanized Pipe Fittings
Differences Between Hot-Dip Galvanized Pipe Fittings and Electro Galvanized Pipe Fittings Galvanized pipe fittings are widely used in various industries for corrosion protection. There are two main galvanizing methods: **hot-dip galvanizing (HDG) and electro galvanizing (electro-galvanizing)**. Here are the key differences between them: 1. Process – Hot-Dip Galvanizing (HDG): – The steel pipe tube are immersed in molten zinc (around 450°C) to form a thick, durable zinc coating. – The zinc bonds metallurgically with the steel, creating a robust protective layer. – Cold-Dip Galvanizing (Electro-Galvanizing): – A thin zinc layer is applied through electroplating, where zinc is deposited on…
