What would 1 pipe coming from a piece of building equipment be?

• A. An Expansion Tank
• B. A Storage Tank
• C. A Pressure Vessel
• D. A Condensate Tray

Answer: (A)

In many building systems, a pipe that exits a piece of equipment with only a single connection often signals an expansion/relief path for a closed loop. An expansion tank is designed to be connected by one line to the heating or cooling circuit so it can absorb the extra volume when the fluid warms and expands. This single-connection setup is the telltale sign that the component is an expansion tank, as its job is to keep system pressure stable by accommodating thermal expansion. A storage tank typically has multiple connections for filling and drawing fluid, and possibly vents. A pressure vessel is built to withstand high pressure and also usually has several penetrations for connections, safety devices, and outlets. A condensate tray collects condensate from equipment and routes it away via a drain line; while it may have a single drain, its primary role is drainage rather than serving as the expansion/pressure-relief component of a closed loop.
