Copper tube is widely used in water heating and ventilation applications, it is strong, durable and natural rust; because copper is recyclable, it is an environmental protection solution for many applications. Although copper tubes have existed for more than half a century, many people are not familiar with their manufacturing methods. In this paper, we will discuss the manufacturing process of copper tube.


Smelting raw copper

The first step in the manufacturing process of copper tube is smelting raw copper. Raw copper is heated to more than 1300 ℃ in a large furnace, and the crude copper changes from solid to liquid.


All untreated copper contains trace impurities such as nickel and zinc. During smelting, these impurities are separated from copper, and then pure copper is transported and used to make pipes.


Forming a pipeline

The next step in the copper tube manufacturing process is forming. After the raw copper is smelted and purified by removing impurities, it is transferred to a tubular casting, which is essentially a tubular shell. The molten copper is poured into the casting, and then it is allowed to cool.


When it is still in liquid state, the molten copper will be evenly distributed throughout the casting, and with cooling, it will harden to form a pipe with the same shape and size as the casting. After this process is completed, the worker takes out the copper tube from the casting to obtain the rough copper tube.




Processing copper pipe

The last step in the copper tube manufacturing process is the sizing and cleaning. The copper tube is fed through a series of dies and cut to a specific size. Next, the copper tube is cleaned with water or solvent to make it more smooth.


conclusion

The manufacture of copper tube is divided into three basic steps: first, the crude copper is smelted in large furnace. Next, it is poured into a casting having a tube shape. After removal from the casting, it is cut and cleaned and then ready for transportation and sale. For water heating and ventilation applications, it is robust, durable and naturally rust resistant; as copper is recyclable, it is an environmentally friendly solution for many applications.
