Black steel pipe is a pipe which is not galvanized. Why do manufacturers choose “black” as its name?

In 1825, Comelius Whitehouse invented how to form butt-weld, which laid solid foundation for the progress of contemporary tubes. In 1911, John Moon improved the pipe-making process based on the Whitehouse's way. His innovation got a warm welcome by those manufacturers. And there were great demands for the metal pipes. Nowadays, with the development and progress of modern technology, more and more manufacturers begin to combine the traditional producing method with modern technology. Therefore, the production efficiency as well as the quality gets great improvement. ?What's more, the application of X-ray gauges makes sure that every pipe has the uniform wall thickness.
