1Under the West Virginia Contractor Licensing Board definition, which work belongs to the Piping Contractor classification rather than the Plumbing Contractor classification?
A.Installing process, power-plant, air, oil, gasoline, or chemical piping and boilers or pressure vessels joined by thread, weld, solvent weld, or mechanical methods
B.Extending a private water-service line and building drain that serve only plumbing fixtures
C.Setting plumbing appliances and fixture trim adjacent to a dwelling
D.Installing water closets, lavatories, and building sanitary vents inside a residence
Explanation: The Board defines a Piping Contractor as a person whose principal business is process, power-plant, air, oil, gasoline, chemical, or other piping plus boilers and pressure vessels, using thread, weld, solvent-weld, or mechanical joints. Plumbing covers fixtures, vents, and water-supply systems within or adjacent to a building. They are separate West Virginia classifications, and this trade exam is not the plumbing exam.
2Which joining methods does the West Virginia Piping Contractor classification expressly include?
A.Fusion of polyethylene gas service only
B.Lead-and-oakum caulked joints only
C.Soldered copper DWV and hub-and-spigot cast-iron soil pipe only
D.Thread, weld, solvent weld, or mechanical methods
Explanation: The Board classification lists thread, weld, solvent weld, and mechanical joints for process, power-plant, and similar piping and for boilers and pressure vessels. Those four methods are the scope language candidates should expect on this open-book trade exam. Plumbing-only joint types such as hub-and-spigot soil pipe are not the piping classification.
3Which ASME piping code is the usual standard for process and chemical plant piping?
A.ASME B16.5 Pipe Flanges
B.ASME B31.1 Power Piping
C.ASME B31.3 Process Piping
D.ASME B31.9 Building Services Piping
Explanation: ASME B31.3 is the Process Piping code used for petroleum, chemical, pharmaceutical, and similar process plants. B31.1 covers power piping in electric-generation and similar plants. B16.5 is a flange-dimension standard, not a piping-system design code. Matching the fluid service to the right B31 book is a core standards skill in NCCER pipefitting.
4Which ASME code governs power piping such as boiler-external steam and feedwater lines in a generating station?
A.ASME B31.3 Process Piping
B.ASME B31.4 Liquid Pipeline Transportation
C.ASME B31.1 Power Piping
D.ASME B31.8 Gas Transmission
Explanation: ASME B31.1 Power Piping covers piping in electric power-generating stations and similar power services, including boiler-external steam and feedwater. B31.3 is process plant piping. B31.4 and B31.8 are cross-country pipeline transportation codes, not in-plant power piping.
5In North American pipe specifications, what does NPS stand for?
A.Normal Pressure Series
B.National Pipe Standard
C.Nominal Pipe Size
D.Non-Pressurized System
Explanation: NPS is Nominal Pipe Size, a dimensionless size designation. For NPS 12 and smaller it only approximates the inside diameter. For NPS 14 and larger, NPS equals the outside diameter in inches. It is not a pressure rating and is not the same as the actual measured ID or wall.
6For common carbon-steel pipe, which wall designation matches Schedule 40?
A.Standard wall
B.Extra-strong (XS) wall
C.Double extra-strong (XXS) wall
D.Thin-wall / light wall
Explanation: On common carbon-steel sizes, Schedule 40 is the standard-wall designation. Schedule 80 matches extra-strong (XS) on many sizes, and XXS is a still heavier wall. Schedule number is a wall-thickness series, not a pressure rating by itself; allowable pressure also depends on material, temperature, and code.
7A gate valve on a process line is intended primarily for which service?
A.Automatic prevention of reverse flow
B.Relieving overpressure to a flare or drain
C.Fine throttling at a mid-stroke disc position
D.Full-open or full-closed isolation with a nearly unobstructed bore
Explanation: A gate valve is an isolation (block) valve. When fully open the gate lifts out of the flow path and pressure drop is low. Throttling on a partially open gate erodes the disc and seats. Globe valves throttle; check valves stop reverse flow; relief valves limit pressure.
8Which valve type is the usual choice when a piping specification calls for manual throttling or regulating of flow?
A.Gate valve
B.Swing check valve
C.Globe valve
D.Blind flange
Explanation: A globe valve's disc moves relative to a seat so the flow area can be set anywhere between shut and open. The change of direction through the body creates pressure drop but gives controllable regulation. Gate and ball valves are mainly on/off. A check valve is automatic and not a throttle.
9What is the function of a check valve in a process or power piping system?
A.To isolate a line for blinding during a turnaround
B.To mix two process streams in a controlled ratio
C.To allow flow in one direction and automatically stop reverse flow
D.To reduce downstream pressure to a set value
Explanation: A check valve opens with forward flow and closes if flow reverses, protecting pumps, boilers, and process equipment from backflow. Common types include swing, lift, and dual-plate wafer checks. It is not a mixing, pressure-reducing, or isolation device.
10Which fitting changes pipe size on a straight run?
A.Coupling
B.Union
C.Reducer
D.90-degree elbow
Explanation: A reducer (or reducing coupling/swage) joins two different diameters on the same centerline or on an offset centerline. Concentric reducers keep the centerline; eccentric reducers keep a flat top or bottom. Couplings and unions join same-size pipe. An elbow changes direction, not size.
