Journeyman?
A) Designing piping layouts from scratch
B) Ensuring adherence to project specifications and quality workmanship
C) Manufacturing piping components
D) Conducting chemical analyses of fluids
Answer: B
Explanation: A journeyman process pipefitter's duties include installing piping per
specifications, ensuring quality workmanship, and following safety and industry
standards.
4. Why is adherence to ethical conduct important for a process piping journeyman?
A) To meet licensing requirements only
B) To ensure safety, quality, and professional reputation
C) To avoid manufacturing defects
D) To reduce project costs
Answer: B
Explanation: Ethical conduct ensures safety, quality, and professionalism, which are
essential for successful project completion and safety compliance.
5. Which OSHA regulation addresses trenching and excavation safety?
A) 29 CFR 1910
B) 29 CFR 1926
C) 29 CFR 1910.1200
D) 29 CFR 1926.650
Answer: B
Explanation: 29 CFR 1926 covers safety standards for construction, including trenching
and excavation safety practices.
6. Which type of pipe material is most resistant to corrosion and commonly used in
chemical processing?
A) Carbon steel
,B) Stainless steel 316
C) Copper
D) PVC plastic
Answer: B
Explanation: Stainless steel 316 offers excellent corrosion resistance, making it ideal for
chemical applications.
7. What type of fitting is used to connect two pipes at a 90-degree angle?
A) Tee
B) Elbow
C) Reducer
D) Cap
Answer: B
Explanation: Elbows are fittings designed to change the direction of piping, with 90°
elbows being common.
8. Which valve type is best suited for rapid shutoff in a piping system?
A) Globe valve
B) Ball valve
C) Gate valve
D) Check valve
Answer: B
Explanation: Ball valves allow quick opening and closing, making them suitable for
rapid shutoff.
9. What is the primary function of a flange gasket?
A) To provide a decorative finish
B) To ensure a leak-proof seal between flanged joints
C) To connect flanges mechanically without sealing
D) To act as a support bracket
Answer: B
, Explanation: Gaskets fill imperfections between flange faces, preventing leaks and
ensuring a tight seal.
10. Which material is commonly used for high-temperature, high-pressure gasket
applications?
A) Non-metallic rubber
B) Spiral wound gasket
C) Paper gasket
D) Cloth gasket
Answer: B
Explanation: Spiral wound gaskets are designed for high-pressure, high-temperature
environments due to their durability.
11. In flange facing, why is proper bolt-up and torqueing sequence critical?
A) To ensure even gasket compression and prevent leaks
B) To make installation faster
C) To reduce the number of bolts used
D) To prevent flange rotation
Answer: A
Explanation: Proper bolt torque sequencing ensures uniform gasket compression,
preventing leaks and ensuring joint integrity.
12. Which threading standard uses pipe threads that form a seal without additional
sealing compounds?
A) BSPP
B) NPT
C) BSPT
D) Metric
Answer: B
Explanation: NPT threads are tapered and designed to seal through thread
deformation, often used with thread sealant or Teflon tape.
