Seamless Steel Pipe

Seamless steel pipes (SMLS pipe) are manufactured through hot-rolling or cold-drawing processes, where solid steel billets are pierced and formed into pipes in a single piece. The tube body has no weld seams or weld points. This production method significantly reduces stress, resulting in uniform wall thickness and relatively high overall strength. Therefore, seamless steel pipes are highly suitable for high-temperature, high-pressure working environments, as well as corrosive extreme environments. Seamless steel pipes are produced using various manufacturing processes, including hot-rolled, cold-rolled, and cold-drawn, and are available in different materials such as carbon steel, stainless steel, and alloy steel. Due to their excellent mechanical properties, they are widely used in fields such as energy transmission, oil extraction, and industrial manufacturing.
