A good rule of thumb is to install pipe hangers at ___________ intervals along a pipe.

The recommended interval for installing pipe hangers is typically at 3 meters (or 10 feet) along a pipe. This guideline helps ensure that the pipes are adequately supported, preventing sagging, excessive bending, or stress that can lead to joint failure or other damage.

Sufficient support is crucial, especially in refrigeration systems where temperature fluctuations can cause materials to expand and contract. Properly spaced hangers help distribute the weight of the pipes and the fluid within them, allowing for safe operation and maintenance.

While smaller distances, such as 1 meter or 1.5 meters, may offer even more support, they can be impractical in terms of installation time and cost. Distances greater than 3 meters may increase the risk of sagging and other mechanical issues. Therefore, using 3 meters as a standard provides a good balance between structural integrity and practicality in installation.
