1. What is the primary purpose of a pipefitter?
A. To design HVAC systems
B. To install and maintain piping systems
C. To inspect electrical circuits
D. To manufacture pipe materials
B. To install and maintain piping systems
Pipefitters specialize in assembling, installing, and repairing piping systems
for heating, cooling, and industrial processes.
2. What type of drawing shows the layout of a piping system?
A. Orthographic drawing
B. Flow diagram
C. Schematic drawing
D. Isometric drawing
D. Isometric drawing
Isometric drawings represent three-dimensional piping layouts, making it
easier to visualize connections.
,3. Which pipe material is most commonly used for high-pressure steam lines?
A. Copper
B. PVC
C. Carbon steel
D. Aluminum
C. Carbon steel
Carbon steel is durable and capable of withstanding high-pressure and high-
temperature steam conditions.
4. What is the standard angle for a pipe elbow used to change direction?
A. 22.5° and 45°
B. 30° and 60°
C. 45° and 90°
D. 15° and 75°
C. 45° and 90°
Elbows are manufactured mainly in 45° and 90° angles to accommodate
directional changes in piping.
5. Which welding method is most commonly used in pipefitting?
A. MIG welding
B. TIG welding
C. Stick welding (SMAW)
D. Brazing
C. Stick welding (SMAW)
SMAW (Shielded Metal Arc Welding) is widely used in pipefitting because of
its versatility and strength.
,6. A flange is used in piping systems to:
A. Measure pressure
B. Provide a removable joint
C. Support the pipe
D. Change pipe size
B. Provide a removable joint
Flanges allow sections of piping to be bolted together for maintenance and
disassembly.
7. What is the function of a pipe hanger?
A. Increase flow velocity
B. Reduce pipe weight
C. Support and secure piping
D. Connect two pipes
C. Support and secure piping
Pipe hangers support the weight of pipes and maintain alignment.
8. Which tool is used to cut steel pipe?
A. Hacksaw
B. Tubing cutter
C. Pipe cutter
D. Grinder
C. Pipe cutter
Pipe cutters are designed specifically for cutting metal pipes quickly and
accurately.
, 9. What is the primary function of a gasket in a piping system?
A. To increase flow rate
B. To provide a leak-proof seal
C. To reduce pressure
D. To support pipe joints
B. To provide a leak-proof seal
Gaskets are used between flanges to prevent leakage under pressure.
10.Which type of valve is best for throttling flow?
A. Gate valve
B. Ball valve
C. Globe valve
D. Check valve
C. Globe valve
Globe valves are designed for regulating or throttling flow, unlike gate or
ball valves which are for on/off control.
11.Which valve allows flow in only one direction?
A. Ball valve
B. Gate valve
C. Butterfly valve
D. Check valve
D. Check valve
Check valves prevent backflow by allowing flow in one direction only.
12.The term “schedule” in reference to pipes indicates:
A. Length of the pipe
