Class 5 Boiler Practice Exam

True or False: Cold springing is allowed for aligning pipe on refrigeration piping according to ASME B31.5.

1. True

2. False

3. Only for certain materials

4. Requires special techniques

The correct answer is: True

Cold springing refers to the process of aligning pipes in a way that allows for thermal expansion when the system is brought into operation. In refrigeration systems, it is common practice to utilize cold springing to accommodate the different thermal expansions that occur when the refrigeration system is operational, as these systems often face significant temperature variations. According to ASME B31.5, which governs piping systems in refrigeration applications, cold springing is indeed permitted to ensure that the pipes maintain their integrity and functionality as temperatures fluctuate. This method provides a means to pre-position piping in response to these temperature changes, enhancing the overall reliability and performance of the refrigeration system. The allowance for cold springing in refrigeration piping under ASME B31.5 reflects the understanding of how materials respond to thermal changes and the need for practical solutions in engineering design. This practice helps to mitigate stresses that could arise from expansion and contraction, thereby promoting safer and more efficient piping layouts.
