Screening Tools for Piping Systems

Screening Tools for Piping Systems

Screening Tools for Piping Systems

I have a closed drains system on my platform that is fully welded from start to finnish of diameters varying from 2" up to 10" diameter.  There is approximately 5 miles of pipework in the system.  It has multiple elbows and branches and has been in service for 23 years.

I know that there are SRB's in the pipework and need to screen the system to target inspection.

Does anyone know of a quick and reliable method?

RE: Screening Tools for Piping Systems

What comes to mind:

1.  Portions of the closed drain system upto 4";
    RT-DWDI; you can readily identify corrosion
    across the pipeline wall.  

2.  Thickness and or flaw detection survey.

    2.1  Guided Wave-UT to cover considerable pipeline
         lenght. (assess material loss)

3.  Hydrostatic Testing.

4.  Assuming portions of the pipping is U/G ; DCVG/CIPS
    to survey the coating system.

5.  Pipeline profile (Low/High Points) prone to fluid
    accumlation or stagnant conditions.

The above can be utlized to a level of coverage that would
provide assurance; in combination of or all.


RE: Screening Tools for Piping Systems


Thanks for the info.  We have already done random UT & Radiography and found problems.  I am looking at GUL & LORUS at present but have lots of branches & elbows to contend with.

SLOFEC is another option?

Our data is constantly exposed to the danger of being intercepted or stolen as it wends its way over global data networks. Data security measures and measures for protecting intellectual property should not, however, first be implemented when data is exchanged – companies must lay the foundation for these measures within their own organization.
