In-line flaw detector a nominal

diameter 159 mm EasyPig159


In-line flaw detectors (ILFD) EasyPig TM  are in-line inspection tools based on MFL (magnetic flux leakage) technology designed to detect critical defects and features in steel pipelines of smaller diameters, including illegal tapping.

EasyPigTM   Advantages


1.  Low inspection costs due to removal of excessive inspection information, allowing to include in-line inspection using EasyPigTM into routine pipeline cleaning operations

2.  Design allowing to inspect pipelines unpiggable for traditional in-line inspection tools

3.  Brushless design

4.  Pipeline condition monitoring including provision of information on illegal tapping locations

5.  Short term data analysis and report preparation (less than 40 days)




Inspected pipelines.


1.  The following steel pipelines are subject to inspection:

2.  Upstream lines of oil field systems and pressure maintenance lines,

3.  Product pipelines,

4.  In-field and distribution gas pipelines

In-line inspection using EasyPigTM can be performed during routine regular pipeline cleaning.
