Carbon steel tube making machine

A tube making machine (welded pipe production line) is primarily used to continuously form, weld, size, and cut metal strips, such as steel strips, into various specifications of metal tubes. Its working principle involves several key steps: first, the steel strip is fed into the forming section through an uncoiler, where a series of rollers gradually bend it into a tubular shape. Then, in the high-frequency welding section, the tube edges are rapidly heated and pressed together using high-frequency current, forming a seamless weld. The weld bead is then removed by an external or internal scraper, and the tube passes through a sizing section to achieve the final dimensions. After cooling and straightening to ensure precision and surface quality, a length-cutting system cuts the tubes into required lengths, which are then collected or packaged through a conveyor system.

Tube making machines are widely used in various industries, including construction, automotive manufacturing, oil and gas transportation, home appliances, and agricultural machinery. In the construction industry, they produce square, rectangular, and round pipes for structural support. In automotive manufacturing, welded pipes are used in vehicle frames, exhaust systems, and other components. In the energy sector, they are used for producing pipelines to transport oil, gas, and water. Additionally, stainless steel tube making machines are applied in the food processing, chemical, and medical industries to produce corrosion-resistant fluid transport pipes. With their high efficiency and continuous production capabilities, tube making machines play a crucial role in modern manufacturing.
