Seamless pipes are cylindrical, square, or rectangular steel tubes with a hollow center and no visible seams around the circumference. These pipes are manufactured by piercing a solid steel billet or tube, and then shaping it through hot rolling, cold rolling, or cold drawing processes. Due to their hollow structure, seamless pipes are widely used for transporting fluids such as water, gas, and oil. Compared to solid steel sections like round bars, seamless pipes offer the same torsional strength but with significantly less weight, making them an economical choice in structural and mechanical applications. They are commonly used in industries such as oil drilling (for drill pipes), automotive (drive shafts), bicycle manufacturing (frames), and construction (steel scaffolding).
In simple terms, seamless pipes are created by first drilling a hole into a solid steel rod to form a tube blank, then finishing the shape through cold drawing or hot rolling. However, not all pipes that claim to be "seamless" are truly seamless. Many fake seamless tubes on the market are actually welded pipes that have been either directly welded or expanded. Most of these welded pipes have thin walls, which makes the so-called "fake seamless" tubes generally thinner and less durable.
