Carbon steel piping is a durable material made from carbon steel, a steel alloy with iron and carbon. Because of its strength and ability to withstand stress, carbon steel pipe is used in a variety of heavy-duty industries like infrastructure, ships, distillers, and chemical fertilizer equipment.
Carbon steel pipe is a steel pipe with carbon as the main alloying element, and its carbon content is between 0.12-2.0%. According to the different carbon content, carbon steel pipes can be divided into low carbon steel, medium carbon steel and high carbon steel. Different carbon content will affect the hardness, strength and durability of the pipe. In addition, carbon steel pipes can also be classified according to the process structure and use scenario of the pipe, such as welded pipes, seamless pipes, turning pipes, pressure pipes, etc.
The carbon steel pipe can be manufactured using several different techniques, each of which produces a pipe with certain characteristics. These characteristics include strength, wall thickness, corrosion resistance, and temperature and pressure limitations. For example, pipes having the same wall thickness but manufactured by different methods may vary in strength and pressure limits. The pipe manufacturing methods include seamless, butt-welded, and spiral-welded. A seamless pipe is formed by piercing a solid, near-molten, steel rod, called a billet, with a mandrel to produce a pipe that has no seams or joints. A butt-welded pipe is formed by feeding a hot steel plate through shapers that roll it into a hollow circular shape. Forcibly squeezing the two ends of the plate together produces a fused joint or seam. A spiral-welded pipe is formed by twisting strips of metal into a spiral shape, similar to a barber's pole, and then welding where the edges join one another to form a seam. This type of pipe is restricted to piping systems using low pressures due to its thin walls.
