Substituting NDE procedures for a pressure test after major repair may be done only after:
API 510 5.8.8.1
The engineer and inspector have approved.
An example of vessels not covered by API 510 are:
API 510 1.1.1
Vessels officially retired from service and abandoned in place.
ACFM is an acronym for:
ASME SEC 5 Article 15
Alternating Current Field Measurement
A pneumatic testing precedure should be developed by whom before conducting the test?
API 510 5.8.6
Engineer
A signal of discontinuity in the material under nondestructive examination is considered:
API RP 577 3.1.36
Indication
In what type of service should vessels be evaluated for potential fatigue cracking failures and have
appropriate inspections planned?
API 510 5.4.4
Cyclic Service
Corrosion and other damage identified during inspections and examinations must be characterized,
sized, and evaluated per Section 7 (Inspection Data Evaluation, Analysis, and Recording) with
deviations from the inspection plan being approved by whom?
API 510 5.5.1
Inspector or Engineer
Inspection tasks typically associated with hot tapping or welding on in-service equipment should
include:
API 577 11.2.5
Positive Metal Identification (PMI)
Any repair welding should be performed according to a procedure accepted by the:
API 510 8.1.1
Inspector or Engineer
Welding of carbon steel with carbon contents over 0.30%
API 510 8.1.5
May need special attention and preheating to avoid weld cracking.
, Inspector recommendations can be changed or deleted after review by whom?
API 510 6.9
Pressure Vessel Engineer or Inspection
Supervision
Deposited weld metal on the face of a weld preparation or surface that will be part of a welded
joint is referred to as:
API 577 3.1.14
Buttering
Which type of ultrasonic display shows the amplitude of the signal coming from the discontinuity as a
function of time?
API 577 9.9.2.1
A-scan Display
Flame-sprayed aluminum coatings have been used on carbon steels to prevent what damage
mechanism?
API 571 4.3.3.6
Corrosion Under Insulation
What is the effect on time to failure by SSC as material strength, applied tensile stress and
environmental charging potential increases?
API 571 5.1.2.3.3
Decreases
External inspection intervals for vessels in non-continuous service are the same as continuous service
vessels because:
API 510 6.4.2
The external environment does not change.
Per API 510, inspection for CUI shall be considered for duplex stainless steel pressure vessels that
operate at temperatures between:
API 510 5.5.6.1
280°F (138°C) and 350°F (185°C)
Supplemental Essential variables must be addressed on the WPS when:
ASME SEC 9 QW-251.2
Toughness tests are required or specified.
The alternating current field measurement (ACFM) method is an electromagnetic inspection
technique which can be used to detect and size defects that:
ASME SEC 5 Article 15 T-1520
Break the surface of the material.
What form of NDE may not be effective for finding tight, scale filled cracks and should not be used as
the only means of detection for Caustic Stress Corrosion Cracking?
API 571 4.5.3.7
