ASME ASME Pressure Testing and Inspection 1 — Questions and Answers
Question 1: Under ASME Section VIII Division 1, what is the minimum required hydrostatic test pressure for a new pressure vessel?
- 1.1 times the MAWP
- 1.25 times the MAWP adjusted for temperature (Correct answer)
- 1.5 times the MAWP
- 2.0 times the MAWP
Correct answer: 1.25 times the MAWP adjusted for temperature
ASME Section VIII Div 1 requires a hydrostatic test pressure of at least 1.3 times the MAWP multiplied by the ratio of allowable stress at test temperature to allowable stress at design temperature (approximately 1.25-1.3×).
Question 2: Which ASME standard governs the inspection of pressure vessels in continued service (in-service)?
- ASME Section VIII
- ASME Section V
- API 510 (Correct answer)
- ASME Section XI
Correct answer: API 510
API 510 Pressure Vessel Inspection Code governs the inspection, repair, alteration, and re-rating of pressure vessels in continued service (not ASME, but the dominant companion standard in industry).
Question 3: In ASME nondestructive examination, which NDE method is BEST suited for detecting surface-breaking cracks in ferromagnetic materials?
- Radiographic Testing (RT)
- Ultrasonic Testing (UT)
- Magnetic Particle Testing (MT) (Correct answer)
- Liquid Penetrant Testing (PT)
Correct answer: Magnetic Particle Testing (MT)
Magnetic Particle Testing (MT) is best suited for detecting surface and near-surface defects in ferromagnetic materials, using magnetic fields to reveal discontinuities.
Question 4: Under ASME Section V, what is the purpose of a 'written procedure' for nondestructive examination?
- To record the results of each NDE examination
- To document that the NDE technician has been qualified by the employer
- To establish and control the technique variables ensuring repeatable and reliable examination results (Correct answer)
- To report indications to the Authorized Inspector
Correct answer: To establish and control the technique variables ensuring repeatable and reliable examination results
ASME Section V requires written NDE procedures to document technique variables (equipment, calibration, scanning coverage, etc.) ensuring examinations are performed consistently and reliably.
Question 5: What is the minimum required qualification level for an RT film interpreter under ASME Section V and SNT-TC-1A?
- Level I
- Level II (Correct answer)
- Level III
- Any certified level is acceptable
Correct answer: Level II
ASME Section V and SNT-TC-1A require at minimum a Level II certification for personnel interpreting and evaluating radiographic film for code compliance.
Question 6: Under ASME Section VIII, which type of weld joint receives the highest allowable efficiency (E = 1.0)?
- Single-welded butt joint without backing strip
- Double-welded butt joint with 100% radiographic examination (Correct answer)
- Single-welded butt joint with backing strip
- Full penetration corner joint
Correct answer: Double-welded butt joint with 100% radiographic examination
A double-welded full-penetration butt joint with 100% radiographic examination achieves a joint efficiency of 1.0, the maximum allowed under ASME Section VIII Division 1.
