ASME ASME Piping Systems B31 Codes 1 — Questions and Answers
Question 1: Which ASME B31 code governs the design of process piping in industrial facilities?
- B31.1
- B31.3 (Correct answer)
- B31.4
- B31.5
Correct answer: B31.3
ASME B31.3 covers process piping used in petroleum refineries, chemical plants, and similar industrial facilities.
Question 2: ASME B31.1 applies primarily to which type of piping system?
- Gas transmission pipelines
- Refrigeration piping
- Power piping in electric generating stations (Correct answer)
- Building services piping
Correct answer: Power piping in electric generating stations
ASME B31.1 covers power piping found in electric generating stations, industrial plants, and institutional facilities.
Question 3: What is the minimum design margin factor on ultimate tensile strength used in ASME B31.3 allowable stress calculations?
- 2.0
- 3.0 (Correct answer)
- 4.0
- 5.0
Correct answer: 3.0
ASME B31.3 uses a safety factor of 3 on ultimate tensile strength to establish allowable stresses.
Question 4: Which ASME B31 code covers liquid pipeline transportation systems?
- B31.2
- B31.4 (Correct answer)
- B31.6
- B31.8
Correct answer: B31.4
ASME B31.4 governs pipeline transportation systems for liquid hydrocarbons and other liquids.
Question 5: In ASME B31.3, Category M fluid service refers to fluids that are:
- Non-flammable and non-toxic
- Potentially harmful in minute quantities (Correct answer)
- High-temperature steam
- Cryogenic liquids below -100°F
Correct answer: Potentially harmful in minute quantities
Category M fluid service in B31.3 designates fluids where a single exposure can cause irreversible harm even in very small quantities.
Question 6: What does the ASME B31.8 code specifically cover?
- Slurry transportation pipelines
- Gas transmission and distribution piping systems (Correct answer)
- Refrigeration piping
- Cryogenic storage systems
Correct answer: Gas transmission and distribution piping systems
ASME B31.8 covers the design, fabrication, installation, and testing of gas transmission and distribution piping.
