1. Which of the following materials is most commonly used for highpressure
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
,2 PIPEFITTER JOURNEYMAN LICENSURE EXAM PRACTICE

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?

service?
a) Welded joint
b) Threaded joint
c) Soldered (Sweat) joint
