Galvanized elbow pipes are a type of elbow pipe with a zinc coating applied to the surface to enhance corrosion resistance. They are categorized into hot-dipped and electro-galvanized, with hot-dipped having a thicker zinc layer and electro-galvanized being more cost-effective but less smooth. Galvanized elbow pipes are further divided into cold-dipped and hot-dipped, with the former being banned and the latter still recommended for temporary use by the state.

In production, galvanized pipes obtained through direct sales are used, which are commonly utilized for annealing. Another process involves zinc coating after the pipes are manufactured.
