1. What is the primary purpose of an industrial pipe support?
A. To prevent corrosion
B. To support pipe weight and maintain alignment
C. To increase flow rate
D. To regulate pressure
B. To support pipe weight and maintain alignment Pipe supports are
designed to hold the pipe in place, maintain alignment, and prevent sagging
or stress on joints.
2. Which type of pipe fitting is used to connect two pipes of different
diameters?
A. Elbow
B. Tee
C. Reducer
D. Coupling
C. Reducer A reducer fitting allows for a smooth transition between pipes of
different diameters.
3. What is the standard material for industrial steam piping?
A. PVC
B. Copper
C. Carbon steel
D. Aluminum
, C. Carbon steel Carbon steel is commonly used for high-temperature and
high-pressure steam applications due to its strength and durability.
4. What does the term "schedule" refer to in pipe specifications?
A. Wall thickness
B. Diameter
C. Length
D. Material type
A. Wall thickness Pipe schedule indicates the wall thickness, which affects
the pressure rating of the pipe.
5. Which welding method is commonly used for high-pressure industrial
piping?
A. Gas tungsten arc welding (GTAW)
B. Shielded metal arc welding (SMAW)
C. Resistance welding
D. Brazing
B. Shielded metal arc welding (SMAW) SMAW is widely used in industrial
piping due to its adaptability for field conditions and high-pressure
applications.
6. A flanged joint requires which type of sealing?
A. O-ring
B. Thread tape
C. Gasket
D. Welding
C. Gasket Gaskets are placed between flanges to prevent leakage under
pressure.
7. What is the primary hazard associated with cutting or welding pipes
containing flammable substances?
A. Corrosion
B. Fire or explosion
C. Vibration
D. Water hammer
, B. Fire or explosion Residual flammable gases can ignite during welding or
cutting, posing serious safety risks.
8. What is the purpose of a pipe elbow?
A. To reduce pressure
B. To change the direction of flow
C. To join two pipes of different diameters
D. To vent air
B. To change the direction of flow Elbows are used to alter the flow path of
piping systems.
9. What is a common inspection method for welds in industrial piping?
A. Visual inspection
B. Ultrasonic testing
C. Radiographic testing
D. All of the above
D. All of the above Weld inspections may involve visual, ultrasonic, or
radiographic methods depending on the code and application.
10.Which valve is designed to prevent reverse flow?
A. Gate valve
B. Globe valve
C. Check valve
D. Ball valve
C. Check valve Check valves allow flow in one direction and automatically
prevent backflow.
11.What does NPT stand for in threaded piping?
A. National Pipe Taper
B. National Pressure Thread
C. Nominal Pipe Thickness
D. Non-Pressure Thread
A. National Pipe Taper NPT is a standard for tapered threads that seal
pressure-carrying pipes.
