Black steel pipe is uncoated steel, also known as black steel. The dark color comes from iron oxide that forms on its surface during manufacturing. When the steel pipe is forged, a black oxide skin is formed on its surface, giving it the finish seen on this type of pipe.

ASTM A120 black steel pipe is uncoated steel, also known as black steel. The industry uses black pipe as a term to distinguish plain mild steel pipe from galvanized steel pipe. Therefore, black pipe generally refers to any ungalvanized steel pipe.The dark color comes from iron oxide that forms on its surface during manufacturing. When the steel pipe is forged, a black oxide skin is formed on its surface, giving it the finish seen on this type of pipe. Black steel pipe is sometimes called black pipe, black iron pipe, industrial pipe. As mentioned earlier, welding is possible because the product is made of mild steel. But because of the various names used, some people mistook the black pipe for iron, mistakenly believing that welding was difficult.
