The main function of the black steel pipe is to carry propane or natural gas to residential or commercial buildings. The galvanized pipe is the steel pipe with the coating of the zinc materials. The galvanized pipe can be resistant to corrosion. Different from the black steel pipe, the galvanized pipe is mainly used to transport water. What's more, it is also one of the best choices to be used as the scaffolding frames since it can resist corrosion. The black steel pipe is made without seam, so it is better to carry gas than the galvanized pipe. And the black steel pipe is also one of the fire-resistant pipe that can be used for fire sprinkler systems.

It is not proper to use black steel pipe to carry water since the water may corrode the steep pipe actually. As we all know that black steel pipe has no zinc coating. However, it is not properly to use galvanized pipe to transport gas since it will flake off over time.

When it comes to the issue of cost, there is no doubt that the galvanized steel pipe costs more than black steel pipe. The galvanized surface will need the zinc material. While the black steel does not need the coating.
