What is the function of device "A" shown in...

🔍 Key Concepts

• Study the location and shape of device "A" on the shell top and compare it with the other structural parts (supports, hinges, and piping). • Think about how heavy components like tube bundles are normally removed from a condenser shell for maintenance. • Consider the difference between pressure‑carrying piping and simple structural lifting/handling fittings on machinery shells.

💭 Think About

• Does device "A" look more like a piece of piping that could carry feedwater, or like a structural attachment used with rigging gear? Why? • When the unit needs major maintenance, what large internal part has to be withdrawn from the shell, and what kind of external fitting would help you do that safely? • If the shell were to hinge open, where would you logically expect the hinge points to be located relative to the supports, and does "A" match that location?

✅ Before You Answer

• Verify whether "A" is open to the inside of the condenser (like a pipe or nozzle) or is a solid padeye/lug. • Compare "A" with the parts that are clearly piping connections (inlet/outlet nozzles) and with those that are clearly supports/hinges. • Ask yourself if the description "only used during installation" really makes sense for normal maintenance and tube-bundle removal operations on this type of equipment.

What is the function of device "A" shown in the illustration? Illustration MO-0110

It aids in removing condenser tube bundles.

It provides a conduit for incoming feed water.

It is only used as a lifting beam during installation.

It serves as a hinge for ease of opening the shell.
