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.
Carbon steel pipe (CS pipe) is a durable material made of carbon steel, a steel alloy of iron and carbon in which the carbon content is less than 2 percent steel. Carbon steel can be further divided into low carbon steel, medium carbon steel and high carbon steel, mainly depending on the carbon content in the steel. Due to its strength and ability to withstand pressure, carbon steel pipes are used in a variety of heavy industries such as infrastructure, ships, stills, and fertilizer equipment.
Carbon steel meets the requirements of sustainable development due to its high recyclability and renewability. Waste carbon steel materials can be recycled through smelting and reprocessing, reducing resource consumption and environmental impact.
As a basic industrial material, carbon steel plays an important role in various fields. Through continuous research and improvement of its performance, its irreplaceability in modern industry is ensured. With the advancement of technology and the strengthening of awareness of environmental protection, the production and application of carbon steel will pay more attention to efficiency and sustainability.
