1. What is the primary purpose of a pipefitter’s pipe wrench?
A. Cutting pipe
B. Measuring pipe
C. Gripping and turning threaded pipe and fittings
D. Flanging pipe
Answer: Gripping and turning threaded pipe and fittings
Rationale: A pipe wrench is designed to provide a strong adjustable grip for
turning threaded pipe and fittings during installation or removal.
2. Which tool is commonly used to cut steel pipe cleanly?
A. Cold chisel
B. Pipe cutter
C. Ball-peen hammer
D. Screwdriver
Answer: Pipe cutter
Rationale: A pipe cutter produces a controlled, generally square cut and is
commonly used when preparing pipe for threading or joining.
3. What is the main purpose of pipe threading?
,A. To reduce pipe diameter
B. To polish the pipe
C. To create threads for joining threaded fittings
D. To remove corrosion
Answer: To create threads for joining threaded fittings
Rationale: Threading forms helical grooves that allow compatible threaded
fittings to be securely connected to the pipe.
4. Which fitting is used to change the direction of a piping run?
A. Union
B. Coupling
C. Elbow
D. Bushing
Answer: Elbow
Rationale: Elbows redirect piping, commonly by 45 or 90 degrees, while
maintaining the flow path.
5. What is the function of a pipe union?
A. To permanently weld two pipes
B. To allow a pipe section to be disconnected without rotating the entire pipe
C. To increase water pressure
D. To reduce pipe temperature
Answer: To allow a pipe section to be disconnected without rotating the entire
pipe
Rationale: A union provides a separable connection that is especially useful
when equipment or piping sections must be serviced.
6. What fitting is normally used to connect pipes of different diameters?
,A. Elbow
B. Cross
C. Reducer
D. Cap
Answer: Reducer
Rationale: A reducer transitions between different pipe sizes while maintaining
a connected flow path.
7. What is the primary function of a pipe support?
A. Increase pipe pressure
B. Support the pipe’s weight and control movement
C. Increase pipe velocity
D. Change fluid chemistry
Answer: Support the pipe’s weight and control movement
Rationale: Proper supports prevent excessive sagging, stress, vibration, and
movement of piping systems.
8. Why are pipe hangers important in a hospital piping system?
A. They eliminate the need for valves
B. They safely support piping and help maintain proper alignment
C. They increase electrical voltage
D. They replace insulation
Answer: They safely support piping and help maintain proper alignment
Rationale: Hospital piping requires reliable support to maintain system integrity
and prevent damage or unsafe movement.
9. What is the purpose of pipe insulation on a hot-water line?
A. Increase corrosion
B. Reduce heat loss and protect personnel from hot surfaces
, C. Increase pipe weight
D. Increase water contamination
Answer: Reduce heat loss and protect personnel from hot surfaces
Rationale: Insulation conserves energy and reduces the risk of burns from
exposed hot piping.
10.What does a pressure gauge measure?
A. Pipe length
B. Flow direction
C. Pressure within the system
D. Pipe wall thickness
Answer: Pressure within the system
Rationale: A pressure gauge indicates the pressure exerted by the fluid or gas
within the connected piping system.
11.What is the purpose of a shutoff valve?
A. Increase pipe diameter
B. Stop or isolate flow through a piping section
C. Measure temperature
D. Filter electricity
Answer: Stop or isolate flow through a piping section
Rationale: Shutoff valves allow sections of piping and equipment to be isolated
for maintenance, repair, or emergencies.
12.Which valve is commonly used where reliable isolation is required in a
piping system?
A. Check valve
B. Gate valve
