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 high-efficiency 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.
The processing methods for Shenyang purple copper threaded pipes generally include twisting method, rolling method, extrusion method, and rolling method. They are usually used to process large-diameter wall thickness threaded pipes, and the processing accuracy is not high. For small heat exchangers, the use of small-diameter, thin-walled stainless steel threaded tubes with poor rigidity and small volume clearly cannot be processed through traditional methods. Therefore, a new type of thread machining process was proposed, and a thread automatic machining control system based on PLC and servo system was designed. The control system has high reliability and automation level, large output, satisfactory machining accuracy, and simple and convenient operation
Single and bimetallic finned tubes:
Our company can provide over a hundred commonly used specifications of single, bimetallic rolled finned tubes and various special specification sheets to our customers. Bimetallic rolled finned tube. Copper and aluminum rolled finned tubes are made by rolling copper or aluminum tubes as a whole, with no contact thermal resistance, high strength, resistance to thermal and mechanical vibrations, good thermal expansion performance, and a considerable expansion heat transfer surface. Heat exchangers made of this finned tube have excellent performance

Our company can provide over a hundred commonly used specifications of single, bimetallic rolled finned tubes and various special specification sheets to our customers. Bimetallic rolled finned tube. Copper and aluminum rolled finned tubes are made by rolling copper or aluminum tubes as a whole, with no contact thermal resistance, high strength, heat resistance to shock and mechanical vibration, good thermal expansion performance, and considerable expansion heat transfer surface. Heat exchangers made of this finned tube have better performance than those made of string or wound heat exchangers. Widely used as heating, drying, condensing, and cooling equipment in the process of petroleum, chemical, metallurgical, textile, electromechanical, light industry, pharmaceutical and other industries.
The overall rolled fins are smooth and free of burrs, wrinkles, and easy to clean. When wet cooling is used in heating and air conditioning projects, condensed water on the outer surface of the fins is easily removed, and dust and scale are not easily formed in drying, heating, and other heat exchange situations.
The aluminum rolled finned tubes and copper rolled finned tubes produced by our factory have undergone anodizing treatment on their surfaces, resulting in a beautiful and elegant color that can effectively prevent surface corrosion.
Process principle (taking copper and aluminum as an example):
Rolled on specialized copper or aluminum tubes using specialized machine tools, it has no contact thermal resistance, high strength, resistance to thermal and mechanical vibrations, good thermal expansion performance, and a considerable expansion heat transfer surface. It is corrosion-resistant, easy to clean, and has a beautiful appearance. The heat exchanger made of this type of finned tube has a considerable expansion of heat transfer area, and its performance is superior to that of string or wound heat exchangers. The product is suitable for working environments with hot air temperatures below 250 degrees Celsius
