The definition of Black Steel Pipe
Black steel pipe is made of steel without the galvanized treatment. The reason why it is called black steel pipe is that it has a dark surface due to the dark-colored iron oxide coating.

The history of Black Steel Pipe
William Murdock is the person who mades the breakthrough in the modern process of pipe welding area. In 1815, he invented a coal burning lamp system and wanted to make it to be used in all of London. He created a continuous pipe which can deliver the coal gas to the lamps with  barrels from discarded muskets. In 1824 James Russell patented a fast and inexpensive way to make metal tubes. He made a tube by joining the ends of flat iron pieces together and then welded the joints with heat. In 1825 the "butt-weld" process is improved by Comelius Whitehouse and it forms the basis for modern pipe making.

The development of Black Steel Pipe
In 1911, John Moon developed the Whitehouse's method again. The improvement allowed manufacturers to create continuous streams of pipe. He employed his technique in the machinery  that he built and the skill is also adopted by many manufacturing plants. Then there is the need for seamless metal pipes. Initially, people by drilling a hole through the center of a cylinder to produce Seamless pipe. However, it was difficult to make sure the holes with the precision needed uniformity in wall thickness. An 1888, with the further development and improvement of the technology
, it allowed for greater efficiency by casting the billet around a fire-proof brick core. The hole will leave in the middle when the brick was removed.
