Is your nuclear
plant water cooling pipelines at risk?
 |
Nuclear
scientists have always felt that the greatest risk in
operating a reactor is the loss-of-coolant accident. If
for some reason the flow of water is stopped or slowed,
for example if a pipe breaks, the fissioning fuel rods
could become so hot that they could melt. |
|
The heat
produced in the fuel rods is more than enough to raise
the temperature of cooling water to its boiling point.
All of the nuclear accidents that have occurred have
been at least partially caused by loss of coolant.
Use of RFT
to evaluate fire suppression piping
Don't let this
happen to you.
PICA is a company that can help identify the condition
of your waste water pipelines using it's patented state
of the art Remote Field Technology (RFT) See Snake tool.
Join the growing list of water and waste water companies
around the world who have used our service. To date PICA
has inspected 660,000' (200 kms) of water mains using
the Hydroscope technique. |

See Snake Tool solution. |
| There is
a demand in the market for improved probability of
detection (P.O.D.) and exceptional accuracy for sizing
of corrosion pits. Competing tools that use Magnetic
Flux Leakage (MFL) require intimate contact with the
pipe wall in order to achieve acceptable flaw sizing.
Unfortunately many pipelines have internal deposits of
wax, scale or sand and others are lined with cement
mortar, epoxy or polyethylene, preventing the effective
use of MFL tools. See Snake technology, on the other
hand, requires no contact with the pipe wall, and can
measure through scale, wax and non-magnetic liners. In
fact, See Snake tools have a minimum clearance of 0.250”
(6.3mm) to allow passage of the tool past weld roots,
dents and internal deposits. |
The See Snake Tool advantage.
1. Non-contact NDT method.
2. Equally sensitive to internal and external flaws.
3. Complete coverage at fast inspection speeds.
4. Accurate results that identify both the severity and location
of areas of wall thinning.
5. Novel mechanical design can accommodate ID variations as well
as traverse sharp bends.
6. Compact and transport friendly.
Adept Pro Software
See Snake 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
labour costs.
The multi-channel See Snake Tools inspect 360° of the pipe.
The data is displayed as color map, strip-chart logs and
voltage planes. The screen capture below shows two pits at 6
o’clock.
