Question

When steam is first being introduced into a piping system, it is important that:

A. All valves be wide-open
B. All drains be closed
C. All valves be closed
D. All condensate water is drained
E. All bypass valves are closed

Answer 1

During the initial introduction of steam into a piping system, it is important to have all valves closed to prevent any dangerous release of steam.

Step-by-step explanation:

When steam is first being introduced into a piping system, it is important that all valves be closed. This is because during the initial introduction of steam, there may be high pressure and temperature, and if the valves are open, it can cause an abrupt and potentially dangerous release of steam. Once the system is stable and operating within the desired parameters, the valves can be gradually opened to control the flow.
