Final answer:
Piping break lines indicate interruptions in piping and are represented by a zigzag pattern in piping drawings. They show the location of valves, pumps, fittings, and other components in a piping system.
Step-by-step explanation:
Piping break lines indicate interruptions in piping. Break lines are typically represented by a zigzag pattern in piping drawings and show where the flow of fluid or gas is interrupted or diverted. They are used to indicate the location of valves, pumps, fittings, and other components in a piping system.
For example, if there is a break line in a pipe drawing, it might indicate the location of a valve where the flow of fluid can be stopped or redirected. It helps engineers and technicians understand the layout and design of the piping system.
Therefore, the correct answer is B. Interruptions in piping.
