PIPEFITTER JOURNEYMAN LICENSURE EXAM
PRACTICE STUDY TEST WITH QUESTIONS AND
ANSWERS| LATEST UPDATED VERSION WITH
VERIFIED SOLUTIONS - ASSURED PASS
1. Which of the following materials is most commonly used for high- pressure steam piping?
a) PVC
b) Carbon steel
c) Copper
d) Aluminum
Rationale: Carbon steel is preferred for high-pressure steam systems due to its strength and heat resistance.
2. What is the standard pipe schedule for a 2-inch nominal diameter pipe used for steam service?
a) Schedule 10
b) Schedule 20
c) Schedule 40
d) Schedule 80
Rationale: Schedule 40 is commonly used for standard steam service piping; higher pressures may require Schedule
80.
3. Which welding process is most often used for joining carbon steel pipes in industrial applications?
a) MIG welding
b) TIG welding
c) SMAW (Stick welding)
d) Oxy-acetylene welding
Rationale: SMAW is widely used for carbon steel pipe welding due to portability and adaptability in field conditions.
4. What is the purpose of a pipe hanger?
a) To insulate the pipe
b) To connect pipe sections
c) To support the pipe and maintain alignment
d) To measure pressure in the pipe
Rationale: Pipe hangers support piping systems and prevent sagging or misalignment.

Rationale: Cutting oil reduces friction and prevents damage to threads during threading.
5. What is the minimum clearance required between steam pipes and combustible materials?
a) 1 inch
b) 2 inches
c) 18 inches
d) 24 inches
Rationale: Steam pipes must be installed with adequate clearance to prevent fire hazards; 18 inches is
standard in many codes.
6. What type of joint is most commonly used for copper piping in water service?
a) Welded joint
b) Threaded joint
c) Soldered (Sweat) joint
d) Flanged joint
Rationale: Copper water piping typically uses soldered joints for secure, leak-free connections.
7. Which tool is used to measure the thickness of pipe walls?
a) Pipe wrench
b) Vernier caliper
c) Micrometer
,3|Page
d) Torque wrench
Rationale: Micrometers precisely measure pipe wall thickness to ensure compliance with specifications.
8. Which valve type is best suited for throttling flow?
a) Gate valve
b) Globe valve
c) Ball valve
d) Check valve
Rationale: Globe valves allow precise flow control and are ideal for throttling applications.
9. What is the purpose of a pressure relief valve in a piping system?
a) To increase pressure
b) To prevent leaks
c) To release excess pressure and prevent system failure
d) To measure pressure
Rationale: Pressure relief valves protect piping systems from overpressure conditions.
10. In which situation should a pipe be annealed after bending?
a) When using PVC pipe
b) When threading galvanized pipe
c) When bending high-carbon steel pipe
d) When connecting flanges
, 4|Page
Rationale: Annealing relieves stress and prevents cracking in high- carbon steel after bending.
11. What is the standard angle for an elbow used to change pipe direction?
a) 30°
b) 45°
c) 90°
d) 120°
Rationale: 90° elbows are the most common for changing direction in piping systems.
12. What type of pipe supports vertical piping runs in a multi-story building?
a) Clevis hanger
b) Wall strap
c) Base support
d) Riser clamp
Rationale: Riser clamps secure vertical pipes and prevent movement between floors.
13. Which of the following is a common defect in welded pipe joints?
a) Corrosion
b) Porosity
c) Bending
