1. What is the primary purpose of a pipe wrench?
A. Cutting pipe
B. Measuring pipe
C. Turning and gripping threaded pipe and fittings
D. Reaming pipe
Answer: Turning and gripping threaded pipe and fittings
Rationale: A pipe wrench is designed to securely grip and rotate threaded pipe
and fittings during installation or removal.
2. Which tool is commonly used to remove burrs from the inside edge of cut
pipe?
A. Pipe vise
B. Reamer
C. Level
D. Flare tool
Answer: Reamer
Rationale: A reamer removes sharp internal burrs created when pipe is cut,
improving flow and protecting seals and fittings.
, 3. What is the purpose of a pipe vise?
A. To heat pipe
B. To hold pipe securely during cutting, threading, or assembly
C. To measure pressure
D. To test electrical continuity
Answer: To hold pipe securely during cutting, threading, or assembly
Rationale: A pipe vise provides stable support and prevents the pipe from
rotating while work is being performed.
4. Which fitting is used to change the direction of a piping system by
approximately 90 degrees?
A. Coupling
B. Union
C. Elbow
D. Reducer
Answer: Elbow
Rationale: Elbows are manufactured in various angles, with 90-degree elbows
commonly used to make right-angle changes in piping direction.
5. What is the primary purpose of a union in a piping system?
A. To permanently weld two pipes together
B. To allow a section of piping to be disconnected easily
C. To reduce pressure
D. To increase pipe diameter
Answer: To allow a section of piping to be disconnected easily
Rationale: A union provides a convenient mechanical connection that can be
separated for maintenance or equipment replacement.
6. Which fitting is used to connect pipes of different diameters?
,A. Elbow
B. Reducer
C. Cap
D. Cross
Answer: Reducer
Rationale: A reducer transitions the piping system from one pipe diameter to
another.
7. What is the purpose of a pipe cap?
A. To increase flow
B. To close the end of a pipe
C. To measure pressure
D. To filter water
Answer: To close the end of a pipe
Rationale: A cap provides a closed termination at the end of a pipe or fitting.
8. Which device is used to prevent reverse flow in a piping system?
A. Gate valve
B. Check valve
C. Globe valve
D. Strainer
Answer: Check valve
Rationale: A check valve automatically permits flow in the intended direction
while preventing reverse flow.
9. Which valve is generally preferred when the primary function is full-flow
isolation?
A. Gate valve
B. Globe valve
, C. Needle valve
D. Mixing valve
Answer: Gate valve
Rationale: Gate valves are commonly used for on/off isolation because, when
fully open, they provide relatively little resistance to flow.
10.Which valve is commonly used for throttling or regulating flow?
A. Globe valve
B. Gate valve
C. Check valve
D. Foot valve
Answer: Globe valve
Rationale: Globe valves are designed to regulate flow effectively because of the
configuration of their internal passage and disc.
11.What does NPT stand for?
A. National Pipe Thread
B. New Pressure Technology
C. National Plumbing Tube
D. Normal Pipe Tolerance
Answer: National Pipe Thread
Rationale: NPT is a standardized tapered thread form widely used for
connecting piping and fittings in many applications.
12.Why are tapered pipe threads useful?
A. They eliminate all need for fittings
B. They can form a tight threaded connection
C. They increase pipe diameter
D. They prevent all corrosion
