What is the minimum distance between support clamps for refrigerant piping?

The minimum distance between support clamps for refrigerant piping is 48 inches. This requirement is established to ensure proper support and stability for the piping system. When refrigerant lines are adequately supported, it helps prevent issues such as sagging or vibration, which can lead to wear and tear or even failure of joints and connections over time.

Supporting refrigerant piping at the correct intervals also allows for thermal contraction and expansion that occurs with temperature fluctuations in the system. Adequate support is crucial because improper spacing may result in increased stress on the piping, which can lead to refrigerant leaks or system inefficiencies.

It's important to adhere to this guideline in marine environments, where movement and vibrations from the sea can further compromise the integrity of the refrigerant piping if not properly supported. Thus, following the 48-inch rule not only aligns with best practices but ensures the reliability and efficiency of the cooling system in maritime applications.
