Which component should be installed near an expansion loop in a piping system?

In a piping system, an expansion loop is designed to accommodate the thermal expansion and contraction of the piping material as temperatures fluctuate. Installing an anchor near an expansion loop is crucial because it provides a fixed point that prevents unwanted movement of the pipe. This helps to maintain the integrity of the entire system and stabilizes the structure by allowing the expansion loop to effectively absorb thermal movement without imposing additional stress on the pipes or supporting structures.

An anchor is essential for controlling the axial displacement of the piping, allowing the expansion loop to function as intended. When the pipe expands due to heat, the loop will absorb this movement, but without an anchor, the pipe could potentially shift too much, leading to misalignment, increased wear, or even failure of connections and components.

In contrast, other components such as air vents, valves, and strainers serve different functions within a piping system. Air vents are primarily used to release trapped air, valves control flow, and strainers filter out unwanted debris, but they do not assist with managing the movement of the piping associated with thermal expansion. Therefore, the incorporation of anchors near expansion loops is a critical practice in piping design to ensure system stability and longevity.
