What does seamless mean in piping?

In piping, "seamless" means that the pipe has been manufactured without any weld or seam along its length. This is achieved by extruding or drawing a solid steel billet into a hollow tube without any welding or joining of pieces, creating a continuous structure with no visible joints. Because of the lack of a welded seam, seamless pipes tend to have better strength, uniformity, and pressure-handling capabilities compared to welded pipes, making them especially suitable for high-pressure applications such as oil and gas transportation, chemical processing, and high-temperature environments.

Seamless pipes are often preferred in situations where safety, durability, and performance are critical due to their structural integrity, as they do not have the potential weak points that welded seams might introduce.
