Internal Pipeline Integrity Tool |
 |
|
|
|
The I-PIT
System represents a new technological
breakthrough for the rapid inspection of
pipelines for internal and external flaws; and
is especially designed for pit detection and
sizing. |
|
|
 |
A typical
I-PIT tool is shown to the left, just after
inspection of a 6" (150mm), 0.284" (7.1mm) wall
thickness, seamless pipeline. The internal
deposits of wax, oil and sand do not affect the
detection of pits in the line. |
|
In fact,
the I-PIT tools have a tolerance of 0.250"
(6.3mm) to allow passage of the tool past weld
roots, dents and internal deposits. |
|
|
 |
I-PIT
tools are introduced to the pipeline at a cut
end and can be pushed by hand or air pressure to
the target distance. |
|
They are
then winched back using a simple hand or
electric-winch. |
|
Inspection
speed is 33'/min (10m/min), and data are
displayed immediately following the inspection,
on a portable computer. |
|
|
 |
|
Data
analysis is semi-automatic and a report is
created as the analysis is being performed.
Depending on the line condition, analysis and
reporting can be done in the field, but is
usually done the next day, off-site, to reduce
labor costs. |
|
|
|
The
multi-channel I-PIT tools inspect 360 degrees of
the pipe and displays the data as color maps,
strip-chart logs and voltage planes. |
|
|
|
Unlike MFL
tools, I-PIT tools contain no magnets, so they
can be pushed with relative ease for up to 330'
(100m) each way from an access point. The data
to the right shows two pits located at 6 o'
clock in a gas pipeline. |

|
Applications |
 |
After a pipeline failure: check 100m
each side of the repair for more
corrosion damage. |
|
|
Check an old or abandoned line
before re-commissioning it. |
|
|
Pipelines from 2" (50mm) to 8"
(200mm) diameter, in wall thickness
to 0.375" (9.5mm) |
|
|
Oil + gas, water, sewer, disposal,
chemical and drain lines. |
|
|
Carbon steel and certain non-ferrous
lines. |
