That portion of the steam drum, containing a manhole for internal access to the drum, for the purpose of cleaning, inspecting, and carrying out repairs, is called the __________.

🔍 Key Concepts

• Steam drum construction – understand what each part (wrapper, tube sheet, drumhead, end plate) actually is on a boiler/pressure vessel • Purpose of a manhole – why you need it and where it is usually placed for internal access, cleaning, and inspection • Pressure‑retaining parts vs. tube connections – which parts are mainly for enclosing the drum ends, and which are for supporting tubes

💭 Think About

• For a steam drum, which part forms the main cylindrical shell, and which parts close off the ends? Match those ideas to the terms in the choices. • Which term is most commonly associated with having a large opening (manhole) built into it so a person can enter the drum? • Think about where the tubes actually enter the drum—what is that surface called, and is that usually where a full-size manhole is located?

✅ Before You Answer

• Be sure you know the difference between a shell/wrapper (the curved side) and the ends of a drum. • Confirm which term is typically used for the flat or slightly dished plate that closes the drum end and may contain a manhole. • Verify which term, if any, is specifically associated with supporting or securing tubes rather than providing personnel access.
