When full loops are to be fitted in a confined space, ... The expansion loop can be fabricated from lengths of straight pipes and elbows welded at the joints (Figure 10.4.9). An indication of the expansion of pipe that can be accommodated by these assemblies is shown in Figure 10.4.10. It can be seen from Figure 10.4.9...

If all the legs are the right length and the anchors and guides are placed correctly then you will not need additional methods to compensate for the expansion. 3. Expansion loops. In long straight runs of pipeways pipe expansion loops are added to compensate for the thermal expansion.

Expansion joints are used in piping systems to compensate for changes in pipe length due to piping temperature changes, particularly where spatial constraints preclude the use of expansion loops in the piping.

This system allows the use of the entire surface area of the tubing to contact the pipe increasing the heat transfer rate by 1000% or more over bare convection tracers of the same size.
