1. What is the primary responsibility of a supervising pipefitter on a large
mechanical installation?
A. Perform only material deliveries
B. Supervise pipefitting work, personnel, safety, quality, and proper installation
C. Operate hospital elevators
D. Perform only administrative paperwork
Answer: Supervise pipefitting work, personnel, safety, quality, and proper
installation
Rationale: A supervising pipefitter is responsible for coordinating workers,
ensuring proper installation, enforcing safety procedures, inspecting
workmanship, and maintaining efficient operations.
2. Which device is commonly used to prevent reverse flow in a piping system?
A. Gate valve
B. Check valve
C. Globe valve
D. Pressure-reducing valve
Answer: Check valve
,Rationale: A check valve permits flow in one direction and automatically closes
when flow attempts to reverse.
3. What is the primary purpose of a steam trap?
A. Increase boiler pressure
B. Remove condensate and non-condensable gases while minimizing steam loss
C. Increase water temperature
D. Reduce pipe diameter
Answer: Remove condensate and non-condensable gases while minimizing
steam loss
Rationale: Steam traps discharge condensate and air from steam systems while
retaining live steam under normal operating conditions.
4. What type of valve is generally preferred when full-flow, low-resistance
shutoff is required?
A. Gate valve
B. Needle valve
C. Check valve
D. Float valve
Answer: Gate valve
Rationale: A gate valve provides relatively unrestricted flow when fully open
and is commonly used for isolation rather than throttling.
5. What is the purpose of a pressure-reducing valve in a steam system?
A. Raise downstream pressure
B. Maintain a lower controlled downstream pressure
C. Remove condensate
D. Increase pipe size
Answer: Maintain a lower controlled downstream pressure
,Rationale: A pressure-reducing valve automatically regulates higher upstream
pressure to a controlled lower pressure downstream.
6. What is water hammer?
A. A type of pipe cutting tool
B. A pressure surge caused by sudden changes in fluid flow
C. A boiler cleaning process
D. A method of pipe insulation
Answer: A pressure surge caused by sudden changes in fluid flow
Rationale: Rapidly stopping or changing flowing fluid can create pressure waves
that produce banging, vibration, and potentially severe piping damage.
7. What is the main purpose of pipe insulation on a steam line?
A. Increase heat loss
B. Reduce heat loss and protect personnel from hot surfaces
C. Increase pipe weight
D. Prevent all pipe expansion
Answer: Reduce heat loss and protect personnel from hot surfaces
Rationale: Insulation conserves energy, maintains system temperature, and
reduces burn hazards from hot piping.
8. Which instrument is commonly used to measure pressure in a piping
system?
A. Thermometer
B. Pressure gauge
C. Level rod
D. Tachometer
Answer: Pressure gauge
, Rationale: Pressure gauges are designed to indicate the pressure within a piping
system or vessel.
9. What should be done before opening a pressurized pipe connection?
A. Strike the pipe with a hammer
B. Isolate, depressurize, drain, and verify zero energy
C. Increase system pressure
D. Remove insulation immediately without checking the system
Answer: Isolate, depressurize, drain, and verify zero energy
Rationale: Stored pressure and hot fluids can cause severe injuries. Proper
isolation and verification are essential before breaking containment.
10.What is the purpose of a union in piping?
A. Permanently weld two pipes together
B. Allow a piping section to be disconnected for maintenance
C. Increase system pressure
D. Prevent all thermal movement
Answer: Allow a piping section to be disconnected for maintenance
Rationale: A union provides a removable mechanical connection that facilitates
equipment replacement and maintenance.
11.What is the function of a flange?
A. Measure temperature
B. Provide a bolted connection between piping, valves, or equipment
C. Reduce electrical voltage
D. Remove air from a boiler
Answer: Provide a bolted connection between piping, valves, or equipment
Rationale: Flanged connections allow piping and equipment to be joined and
later separated for inspection or maintenance.
