What is the difference between black iron and galvanized malleable iron pipe fittings?

Differences Between Black and Galvanized Pipe Fittings

Galvanized pipe fittings are zinc-coated, enhancing their resistance to corrosion and preventing the buildup of mineral deposits that could obstruct the pipe. This makes galvanized pipes suitable for water distribution in residential and commercial buildings, and they are also favored for scaffolding due to their rust-resistant properties.

Galvanized pipe fittings are widely utilized across various outdoor and industrial settings due to their exceptional corrosion and salt resistance. They are suitable for a wide range of applications, excluding underground installations. While they perform optimally with cold water systems, they can also be employed with hot water setups. The primary benefit of galvanized fittings lies in their superior rust resistance compared to black and copper fittings. It's important to note, however, that galvanized pipe fittings are not recommended for use in gas applications.

Black pipe fittings are used to make connections to black iron pipe. Black iron pipe is also most often used in fire sprinkler systems due to its high heat resistance and for water supply lines due to its resistance to water damage.

Since it has a dark color surface which is formed by iron oxide during the manufacturing process, it is called black steel pipe.

Black steel pipe is uncoated and it is widely used for transporting gas like propane and natural gas to residential and commercial buildings.
