ASME ASME Pressure Testing and Inspection

Question 1

Under ASME Section VIII Division 1, what is the minimum required hydrostatic test pressure for a new pressure vessel?

Accepted Answer

1.25 times the MAWP adjusted for temperature

Answer

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)?

Accepted Answer

API 510

Answer

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?

Accepted Answer

Magnetic Particle Testing (MT)

Answer

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?

Accepted Answer

To establish and control the technique variables ensuring repeatable and reliable examination results

Answer

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?

Accepted Answer

Level II

Answer

ASME Section V and SNT-TC-1A require at minimum a Level II certification for personnel interpreting and evaluating radiographic film for code compliance.
