Shenyang White Steel Threaded Pipe Editor introduces that threaded pipes, also known as low ribbed pipes, mainly rely on external ribbed pipes (ribbed coefficient of 2-3) to expand the heat transfer area. They are generally used in situations where the heat transfer coefficient inside the pipe is more than twice that outside the pipe. For condensation and boiling outside the tube, it also has a good strengthening effect due to surface tension.
As the core heat exchange element of a heat exchanger, heat exchange tubes are of great significance in improving their heat transfer performance, controlling their volume and mass, saving materials, and improving the efficiency and reducing costs of heat exchangers. The heat exchange tube technology has widely adopted threaded tubes, which have the advantages of high heat transfer efficiency, less scaling, small volume, and material saving compared to traditional smooth tubes. Threaded pipes work in harsh environments such as high temperature, high pressure, and corrosive gases for a long time, which requires high corrosion resistance and stability. At the same time, considering the difficulty of production methods and processing techniques, copper and aluminum are usually selected as materials for threaded pipes. Although aluminum tubes are cheaper than copper tubes, they have disadvantages such as poor welding processing technology, poor heat transfer performance, and are easily damaged by metal expansion heads during tube expansion, and have not been widely used. In recent years, with the continuous increase in copper prices and the significant decrease in stainless steel prices, the production process of stainless steel pipes has been constantly improving. Stainless steel threaded pipes, as a substitute material with superior performance and lower cost, have broad application prospects.
