What is the available size range for unprotected, soft, annealed copper tubing used for refrigerants?

The size range for unprotected, soft, annealed copper tubing used for refrigerants is typically between 6-35mm. This range is significant because it reflects the industry standards for the types of copper tubing that are suitable for refrigerant applications.

Soft, annealed copper tubing is preferred for refrigerants because it is pliable and can be bent easily, which is essential for fitting within the constraints of the refrigeration system. The specified size range offers a variety of tubing diameters that can accommodate different refrigerant flow requirements and system designs.

Understanding this size range is crucial for refrigeration operators when selecting the appropriate tubing for installations, ensuring compatibility with fittings and other components, and maintaining system efficiency and safety.
