Carbon Steel Pipes

The term carbon steel pipe is quite broad in scope and can be used to describe a wide range of metal tubular goods whose main alloying element is carbon. Although many of the same manufacturing principles apply to both carbon steel pipe and various similar alloy tubular goods, the focus of this narrative will be on the manufacturing process of mild carbon steel pipe goods commonly used for oil and gas as well as water transmission, structural applications, general purpose casing, piling, and mechanical components.

Carbon steel pipe starts out by arriving at the pipe mill in the form of either a billet (basically a large solid steel bar) or a coil (imagine a roll of toilet paper made out of steel). Depending on the manufacturing method used by the mill, these billets or coils will be processed to yield the finished end product. We will examine the various manufacturing methods used to make carbon steel pipe, but first let's look at how the carbon steel got here in the first place.

    

MANUFACTURING PROCESS

Humans have been melting iron ore through a process called smelting for thousands of years. Molten or semi-molten iron would be hammered (forged) or poured into their desired shapes and allowed to cool. People quickly discovered that the properties of the finished product (strength, ductility, longevity) could be controlled in many ways; manipulating cooling time and conditions or adding/removing certain media for example. Carbon steel was one such popular derivative of raw iron made by introducing elemental carbon into the smelting process in the form of charcoal. As useful as steel was, it was time and labor intensive to produce, thus making it generally a poor material for mass consumption. In the mid 19th century, the Bessemer process was patented where by molten pig iron (cheaply made and full of high carbon, silicon, and manganese impurities) is subject to blasts of oxygen which oxidize the impurities thus making them simple to remove from the molten steel. This method of removing excess elements was much easier and cheaper than adding alloying elements to iron, and is directly responsible for the industrial revolution and the beginning of the mass production of carbon steel. Today the technology has changed, but the same basic principles of the Bessemer Process are still the backbone for modern raw steel production.

TIME TO MAKE THE PIPE

Billets and coils are delivered to the pipe mill ready to be made into carbon steel pipe. Depending on the capabilities of the pipe mill and the end use of the final product, the casts will be formed into pipe by means of four distinct different manufacturing methods; seamless, electric resistance weld (ERW), double submerged arc weld (DSAW), or spiral weld.
