Carbon steel pipe is most commonly used in critical engineering applications. It can also be used in automotive applications or structural applications. Carbon steel piping is important in applications ranging from oil and gas to control lines or power lines. Determine whether you need seamless carbon steel pipe or welded carbon steel pipe based on the job at hand.
Welded carbon steel pipe is made from otherwise flat carbon steel. This piece of carbon steel is rolled and welded to create a weld that runs a long distance along the carbon steel pipe or pipe. Welds are formed by melting localized metals together using a high-energy source. Therefore, a weld is formed when pressed together. You’ll notice that the welds are weld beads. This will be a step up from the rest of the carbon steel pipe. You’ll find some seams treated to be more flush with the pipe, while others are sold “as welded,” meaning they stay welded and require no further work on the carbon steel.
