There are several differences between carbon steel piping and black steel piping. These differences also account for why these pipes are used for different applications.

Susceptibility to Erosion

One of the main differences between carbon steel and black steel is that carbon steel piping and carbon steel pipe fitting are susceptible to corrosion. Black steel piping, on the other hand, is made from non-galvanized steel and is not susceptible to corrosion.

Composition

Carbon steel, as its name suggests, has a high carbon content. On the other hand, black steel gets its name from the dark-colored iron oxide that is used to coat its surface. Apart from that, black steel piping is made using several grades of malleable iron. Unlike this technique, when making carbon steel piping, it is made in a seamless fashion. That means carbon steel pipe fitting can be used for applications that require a very high capacity to withstand pressure.

Difference in Outlooking

Black steel piping is mainly used to carry gas into commercial buildings. This pipe is seamless, and this makes it perfect for carrying gas. Also, this pipe is more fireproof than carbon steel piping. Therefore it is also used in fire sprinkler systems. Carbon steel piping, on the other hand, is mainly used for carrying water into homes and commercial properties. This pipe is susceptible to corrosion, which is why it requires galvanization. Hence, it is also used as a scaffolding frame.

Eco-friendliness

Making use of steel for pipes is both safer for people and the environment. Research shows that black steel is more eco-friendly than carbon steel when it comes to CO2 emissions during manufacturing. There are more than 100 major projects where flanges, piping, and various pipe fittings will be needed in the next five years. This means that if the environment is to be considered, most of these projects might use black steel instead of carbon steel pipe fitting due to its low carbon content.

For any offered pressure, carbon steel piping is cheaper than black steel. This is because it can be made much thinner. It also has a higher carrying capacity than black steel pipes with the exact same diameter. Also, its versatility makes it cost-effective. However, there are a lot of other considerations that are made when choosing the right type of steel piping.
