Repair Organization
Which code provides requirements for Hot Tapping?
API 2201
Catalytic reformer vessels may have creep damage if the operating temperature is
above:
900°F
The maximum inspection interval for a pressure relief device in normal service is
based on:
acceptable performance of the device with a maximum interval of 5 year.
A carbon steel vessel in caustic service has a temperature excursion up to 425°F.
The vessel wall is 1/2" thick. No PWHT has been performed. What type of
deterioration could be expected?
Stress corrosion cracking
During a vessel repair or alteration, when can controlled deposition welding be
used as an alternative for post weld heat treating?
For P1, P3, & P4 materials
All RBI assessments must be:
thoroughly documented.
Once vessel repair work is complete, who should approve the finished work?
Authorized inspector
Which of the following activities is not included in the scope of API 510?
Operating a vessel
Which type of corrosion is most easily missed by a visual examination?
Uniform corrosion
The maximum allowable working pressure of a vessel is the:
maximum pressure permitted at the top of the vessel.
The use of a fillet weld patch on a vessel's pressure boundary requires approval
from the:
Authorized inspector and the pressure equipment engineer
During alterations, fabrication approvals (hold points) shall be designated by:
authorized inspector
Per API 510, a PRV repair organization must:
Have a fully documented quality assurance system and training program
During vessel repairs or alterations, welding records shall be:
Available to the authorized inspector
, Repairs Of vessel cracks at a serious stress concentration requires approval by:
pressure vessel engineer
The seating surfaces on a relief device must have a flatness of:
3 light beads/bands
An "F" on the radiograph indicates:
The IQI is placed on film side
An inspector is evaluating a corroded area on the vessel per API 510. The area is
marked off in a grid with five longitudinal lines. Multiple thickness readings are
taken on each longitudinal line. When performing remaining life calculations for
this corroded area, the current thickness reading to use in the calculation is the:
Average thickness of the longitudinal line with the lowest average
API 510 takes effect:
Once the vessel is placed in service
Erosion or corrosion in an exchanger shell that is adjacent to the bundle baffles
can be most easily found during an internal inspection with:
Flashlight beam directed parallel to the shell's internal surface
During a vessel repair, if a preheat is substituted for a post-weld heat treatment,
who is required to review this substitution?
Pressure vessel engineer
Which of the following is NOT an acceptable method for repairing a locally
thinned area that is below acceptable thickness?
Install a thick-film coating to arrest the corrosion
When qualifying a weld procedure using the SMAW process, which variable is
considered an essential variable?
Filler rod "F-number"
The remaining life of a vessel is 8 years. What is the maximum interval for the
external inspection?
4 years
An exchanger shell has a locally corroded area. The owner decides to repair this
area with weld buildup. During this repair, the shell should be:
checked for distortion
What is considered a vessel alteration?
replacement of a hemispherical head with a tori-spherical head
Widely scattered pits can be ignored provided the extent of the pitting does NOT
exceed:
7in squared in an 8in diameter circle
When weld build up is performed in a corroded area what must be done:
area should be examined with MT or PT prior to welding
If preheating is performed in lieu of a PWHT, what is the minimum preheat temp
that must be maintained during welding?
300F
A brittle fracture
grows very rapidly with minimum deformation prior to failure
Which welding process requires the uses of a non-consumable electrode?
GTAW
Companies that use API 510 must
