Refrigeration lines should be secured every how many inches?

In the context of securing refrigeration lines, the requirement for spacing relates to ensuring that the lines remain stable and do not experience undue stress or damage caused by movement or vibrations. Proper support of refrigeration lines is critical to prevent sagging, which can lead to kinks, leaks, or other failures within the system.

The correct answer indicates that refrigeration lines should be secured every 48 inches. This spacing is typically based on standard practices and compliance with industry guidelines, which help ensure the integrity and efficiency of the refrigeration system. Proper support spacing allows the lines to expand and contract as needed without the risk of damage due to inadequate support.

While closer spacing (like 12", 18", or 24") may provide additional support and might be seen in certain situations based on specific applications or local codes, the general standard for many installations allows for 48 inches as a safe and effective distance for securing refrigeration lines. This provides an appropriate balance between sufficient support and practical installation considerations.
