Black steel pipe is the uncoated steel and is also called as black steel.
黑暗的颜色来自于氧化铁形成its surface during manufacturing. When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe.
Galvanized steel pipe是钢,覆盖着一层啊f zinc metal. During galvanizing, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Galvanized pipe is covered with a zinc material to make the steel pipe more resistant to corrosion.
The primary purpose of black steel pipe is to carry propane or natural gas into residential homes and commercial buildings. The pipe is manufactured without a seam, making it a better pipe to carry gas. The black steel pipe is also used for fire sprinkler systems because it is more fire-resistant than galvanized pipe. The primary use of galvanized pipe is to carry water to homes and commercial buildings. The zinc also prevents the buildup of mineral deposits that can clog the water line. Galvanized pipe is commonly used as scaffolding frames because of its resistance to corrosion.
The zinc on galvanized pipe flakes off over time, clogging the pipe. The flaking can cause the pipe to burst. Utilizing galvanized pipe to carry gas can create a hazard. Black steel pipe, on the other hand, corrodes more easily than galvanized pipe and allows minerals from water to build up inside it.
