Piping systems are the lifelines of various industrial processes, transporting fluids and gases essential for operations. However, these systems face challenges like thermal expansion, contraction, vibration, and misalignment, which can lead to stress, leaks, or even failure if not managed properly.
How do expansion loops work?
With the loop, the pipe expands into the loop by bending the legs of the loop instead of squeezing the pipe axially. The longer the loop leg, the lesser the force generated in absorbing a given expansion.
Why are they essential?
The presence of expansion loops ensures the reliability and longevity of piping systems. By dampening vibrations and allowing for thermal expansion, these loops prevent costly repairs, downtime, and potential safety hazards.
Guidelines for Loop Sizing:
Position the expansion loop on the side of the hottest line for optimal performance.
Place the expansion loop in the midpoint between two anchors to ensure effective expansion accommodation.
To aid in the proper sizing and placement of expansion loops, an Excel sheet that simplifies the calculation process. It takes into account factors such as pipe material, temperature differentials and Elasticity module.
