Production Process of Copper Tube

Copper tube is a common metal material that is widely used in many fields, such as construction, manufacturing, electronics and so on. The following will introduce the production process of copper tube.

The production process of copper pipe can usually be divided into the following steps:

Copper preparation: first of all, you need to prepare the copper material, which is usually made by using pure copper billets. These copper billets are usually obtained by methods such as electrolysis, casting or smelting.

Hot rolling of the billet: After preheating the copper billet, the billet is continuously rolled through a hot rolling mill to give it the desired shape. This process requires a number of heating and cooling cycles to achieve the desired size and hardness.

Cold Rolling: Cold rolling is done to change the inner and outer diameter dimensions and wall thickness of copper tubes and to improve the surface quality of copper tubes. During the cold rolling process, the copper billet is rolled and stretched several times through a series of rolls to form the copper tube of the required size.

Cleaning and surface treatment: Cold rolled copper tubes usually have some oxides and other impurities that need to be cleaned and treated. A common type of cleaning is through water or acid washing to remove the surface dirt from the copper pipe to improve its surface quality.

Pipe forming: after the previous process, copper pipe can be further formed. Usually, cold-forming, bending, soldering and other methods are used to bend the copper pipe into the required shape, and multiple copper pipes are connected together through soldering or other connection methods.

Heat treatment: For some applications requiring high copper tubes, such as high strength and high thermal conductivity Inspection and quality control: Throughout the production process, copper tubes need to be subjected to a variety of

Inspection and testing are required throughout the production process to ensure that the quality meets the requirements. Common testing methods include chemical composition analysis, physical property testing, dimensional measurements and so on.

Finally, after the above series of process treatment, the copper tube can be made. Copper tube has good thermal conductivity, corrosion resistance and other characteristics, widely used in manufacturing industry, such as refrigeration equipment, petrochemical and other fields. The production process of copper tube not only requires mastery of various material processing techniques, but also good quality control and testing methods to ensure the quality and performance of copper tube.
