cylinder is exactly 1-1/4" thick, and it is used in the repair of a pressure boundary on a U
stamped vessel, the following is a true statement. - Answer-•It may receive spot, full, or
no
radiography depending on
original the original U1 form.
Charpy impact tests are intended to
prove that a material is: - Answer-•tough at the desired MDMT of
the vessel to be constructed
using that material.
What is the maximum allowed time between the testing of pressure relieving devices
per api 519 if it's in a service that promotes fouling of the valve? - Answer-5 years
Who is responsible for the rerating calculations of a section VIII div. 1 vessel? - Answer-
The manufacturer or an owner/user engineer (or his representative)
What is the minimum length of weld
metal to be radiographed for a Welders
Section VIll Div. 1, is very specific about
the number of spot radiographs required
when applying it for quality control, the
basic premise is to: - Answer-•apply the radiographs
immediately after welding in
order to take corrective steps if
needed.
Unless justified by RBI, the maximum interval between external visual inspections for an
above the ground vessel is: - Answer-5 years
What is the maximum inspection interval for a vessel with a remaining safe operating
life of less than four years? - Answer-The full remaining safe operating life up to a
maximum of 2 years.
, Performance Qualification using an NPS
6 inch pipe coupon made of P No. 5
materials utilizing the SMAW process? - Answer-The entire circumference of the pipe
coupon
The two types of impact tests
required by Section VIll Div. 1 are: - Answer-Weld metal and base metal
In Section VIll Div. 1 acceptance of
a radiograph is based on: - Answer-•the ability to see the essential
hole or wire, if a wire type IQI is
used
A spot radiograph of a butt weld in a 1
inch thick shell of a vessel marked RT-3
was found to have a rounded indication,
the dimension of such an indication
according to Section VIll Div. 1 is: - Answer-•None, rounded indications are
not a consideration with spot
radiography.
According to Section IX, all welders
must be re-tested for a process: - Answer-if the welder's ability to make sounds welds
with process is in doubt.
The testing apparatus used, and the
techniques for performing Charpy
impact tests are found in: - Answer-SA-370
When a RBI assessment is used to
extend the internal or on-stream
inspection interval, the assessment
should include a review of the
inspection history and: - Answer-•potential fouling of the vesselAs
pressure-relieving device(s)
"In developing an inspection plan for
a pressure vessel the inspector
should determine: - Answer-•The conditions that affect the
likelihood a damage mechanism
will be active.
is sometimes used to
determine inspection intervals and
the type and extent of future
inspection/examinations. - Answer-RBI
