Product Description
Copper is a transition metal element with the chemical symbol Cu and atomic number 29. Copper is one of the earliest metals used by humans. As early as prehistoric times, people began to mine open-pit copper mines and use the copper they obtained to make weapons, tools and other utensils. Pure copper is a soft metal with a purple-red color. It has good ductility, thermal conductivity and electrical conductivity. Therefore, it is widely used in cables and electrical, electronic components, building materials and alloys. Internally threaded copper tube is a copper tube with excellent performance, and its inner surface is designed with a spiral thread structure. Compared with smooth copper tubes, internally threaded copper tubes have the following advantages. Increase heat exchange area: The internally threaded copper tube improves the heat conduction efficiency by increasing the surface area of the inner wall. Optimize fluid flow state: The internal thread structure optimizes the flow state of the fluid, making the heat transfer more uniform and reducing the temperature gradient. Reduce pressure drop: The internally threaded copper tube reduces the pressure drop of the fluid in the pipeline and improves the efficiency of the system. Reduce the number of connections: The number of connections between copper tubes is reduced, the pipeline layout is simplified, and the cost is reduced. Corrosion resistance, high toughness: The internally threaded copper tube has the characteristics of corrosion resistance, high toughness, and is easy to cut and process.
