Seamless tubes are long strips of steel with a hollow cross-section, featuring no joints around their perimeter. They are manufactured through a specific process that involves heating and rotating the billet to form the tube shape, followed by applying pressure to the billet surface to create the tube's surface. Seamless tubes can be made from carbon steel, alloy steel, or other special materials like stainless steel. Their main characteristics include high strength, excellent wear resistance, and exceptional performance under high pressure and temperature conditions. Seamless tubes are widely used in various industrial sectors, including but not limited to oil, chemicals, power, and aerospace. When selecting seamless tubes, it is necessary to decide on the material and specifications based on actual usage requirements.
