Is it necessary to have a compensation device between the two fixed supports?

Is it necessary to have a compensation device between the two fixed supports? Compensation devices include natural bends, π-shaped compensators, bellows compensators, etc.
If the length of the pipeline exceeds 30 meters, a compensator is required. The distance between the two fixed supports depends on the specific situation. Moreover, why need two fixed supports? One fixed support and one guide support would be sufficient.
I didn’t understand what the person above meant. According to the specifications, only one metal bellows compensator is allowed between two fixed supports. For L-shaped and π-shaped compensators, is it possible to have multiple compensators between the fixed supports?
Specifically, stress calculations can be performed to determine whether compensation is needed; for example, if the distance between the two fixed supports is very short, compensation may not be required
It needs to be installed; otherwise, fixed brackets and guides alone will suffice.
Use software to do the calculation, such as CAESAR II
It depends on the piping layout and temperature; compensation is necessary only when the temperature is high or when there are long straight sections of pipe. By calculating the stresses, it becomes clear whether compensation is needed. Natural compensation can also eliminate stresses. The compensation device mentioned by the original poster seems to refer specifically to expansion joints, and this should be determined based on stress calculations
