1What does MAOP stand for on a natural-gas transmission or distribution pipeline?

A.Maximum Allowable Operating Pressure

B.Minimum Approved Operating Procedure

C.Measured Average Outlet Pressure

D.Maximum Authorized Overpressure Point

Explanation: MAOP is the Maximum Allowable Operating Pressure, the highest pressure at which a pipeline segment may be operated under 49 CFR Part 192 and ASME B31.8. It is established from design, strength test, and operating-history limits, and it must not be exceeded in normal operation.

2Which federal regulation contains the minimum safety standards for transporting natural and other gas by pipeline?

A.40 CFR Part 280

B.29 CFR 1910.120

C.49 CFR Part 192

D.49 CFR Part 195

Explanation: 49 CFR Part 192 is the PHMSA gas-pipeline safety rule covering design, construction, welding, testing, corrosion control, and operation of gas transmission and distribution systems. ASME B31.8 is the aligned industry piping code used to design and install those systems.

3Under 49 CFR 192.5, a Class 1 location is a class-location unit that has how many buildings intended for human occupancy?

A.More than 10 but fewer than 46 buildings

B.46 or more buildings

C.10 or fewer buildings

D.Any area with a four-story building

Explanation: A Class 1 location is an offshore area or any one-mile class-location unit with 10 or fewer buildings intended for human occupancy. Class location sets design factor, test factor, and cover, so counting occupied buildings correctly is a core gas-piping skill.

4What is the minimum cover, in normal soil, for a buried gas transmission line in a Class 1 location under 49 CFR 192.327?

A.18 inches

B.24 inches

C.30 inches

D.48 inches

Explanation: 49 CFR 192.327 requires at least 30 inches of cover in normal soil for a buried transmission line in a Class 1 location. Consolidated rock may reduce that cover to 18 inches. Class 2, 3, and 4 locations, and public-road drainage ditches and railroad crossings, require 36 inches in normal soil.

5What minimum cover, in normal soil, is required for a buried gas transmission line in a Class 3 location?

A.24 inches

B.30 inches

C.36 inches

D.42 inches

Explanation: In Class 2, 3, and 4 locations, 49 CFR 192.327 requires 36 inches of cover in normal soil and 24 inches in consolidated rock. The same 36-inch soil cover applies in drainage ditches of public roads and at railroad crossings.

6Except where a state or local rule allows less cover with extra protection, what is the minimum cover for a buried gas distribution main?

A.12 inches

B.18 inches

C.24 inches

D.36 inches

Explanation: 49 CFR 192.327(b) requires at least 24 inches of cover on a buried main unless an underground structure prevents that cover and additional protection is provided, or a state or municipal law sets a lesser cover for common-trench utility work. Transmission lines in populated class locations need more cover than this main-line minimum.

7Why is a tracer wire or equivalent locating device installed with buried plastic gas pipe?

A.To carry cathodic-protection current to the plastic wall

B.To provide an electrically locatable path so the nonmetallic pipe can be found later

C.To increase the hoop-stress rating of polyethylene pipe

D.To serve as the required grounding electrode for the gas meter

Explanation: Plastic pipe is not electrically conductive, so 49 CFR 192.321 requires a means of locating it after burial. An insulated tracer wire, or another approved locating method, is laid with the pipe so later 811 locates and maintenance work can find the line without guesswork.

8What is the primary purpose of an external coating on buried steel gas pipe?

A.To raise the specified minimum yield strength of the steel

B.To electrically isolate the pipe from the soil and reduce corrosion current

C.To replace the need for a strength pressure test

D.To increase the internal flow capacity of the pipe

Explanation: An external dielectric coating such as fusion-bonded epoxy, extruded polyethylene, or coal-tar enamel isolates the steel from soil electrolyte so corrosion current cannot easily leave the pipe. Coating works with cathodic protection; holidays (coating defects) are the points CP must protect.

9What is the purpose of cathodic protection on a buried coated steel gas pipeline?

A.To heat the pipe so wax and moisture cannot form hydrates

B.To make the steel surface a cathode so soil-side corrosion is suppressed

C.To raise MAOP above the design pressure

D.To replace coating on the entire pipeline

Explanation: Cathodic protection, by sacrificial anodes or an impressed-current system, forces the steel to be the cathode of the electrochemical cell so metal loss at coating holidays is suppressed. 49 CFR Part 192 Subpart I requires coating plus CP on new buried steel pipe, generally applied within one year after construction.

10What does SMYS mean when selecting steel pipe grade for a gas pipeline?

A.Specified Minimum Yield Strength

B.Standard Measured Yearly Stress

C.Safe Maximum Yield of Steel

D.Seam Mill Yield Specification

Explanation: SMYS is the Specified Minimum Yield Strength of the pipe steel, in pounds per square inch. API 5L grades such as X42 and X52 have SMYS of 42,000 psi and 52,000 psi. Design pressure and percent-SMYS hoop stress are calculated from that value.

About the NV A-19B Gas Pipelines Exam

The Nevada A-19B Pipelines and Conduits for Gas Contractor Examination is the official Nevada State Contractors Board trade or management examination administered by PSI Services LLC. The official exam has 40 scored questions. Passing is 70% (28 of 40 points) in 1.5 hours. The examination is open book. Approved center references include NFPA 30 Flammable and Combustible Liquids Code, 2018 (allowed in center). PSI lists USD 95 for one examination portion and USD 140 if taken with CMS; otherwise USD 95 per trade exam (Candidate Information Bulletin updated 3/25/2026). NSCB requires a separate CMS examination for most new applicants, plus a USD 300 application fee and a USD 600 biennial license fee. This English-language MCQ bank is a study aid, not an official PSI form. It does not replace required trade experience, board approval, fingerprints, bonding, or the official examination.
