The common diameter range of copper capillary tubes is generally between 0.5 mm and 10 mm.
Smaller diameter copper capillary tubes, such as those between 0.5 mm and 2 mm, are often used in applications requiring precise flow control and limited space, such as small instruments and precision refrigeration systems, enabling accurate liquid or gas delivery.
Copper capillary tubes with diameters between 3 mm and 10 mm are suitable for applications with slightly higher flow requirements, such as some medium-sized heat exchangers and small industrial piping systems.
When selecting the appropriate copper capillary tube diameter, it is necessary to comprehensively consider factors such as the specific application scenario, the properties of the fluid, and the flow requirements. A suitable diameter ensures a good fit between the capillary tube and the entire system, guaranteeing stable and efficient fluid delivery, thereby meeting the oper
