Need to Inspect an Unpiggable Pipeline? Russell NDE Can Help!

For decades the in-line inspection of pipelines was dominated by magnetic flux leakage (MFL) tools; however, when faced with unpiggable pipelines, these tools often fail to deliver. There are numerous types of pipelines that cannot be inspected with MFL or ultrasonic instruments. Fortunately, Russell NDE has an innovative pipeline inspection solution for unpiggable or challenging pipeline inspections. Below we'll discuss more what makes a pipeline unpiggable and the tool Russell NDE has created to perform unpiggable pipeline inspections. Continue reading to learn how Russell NDE can assist you with our pipeline inspection services! 

What is an Unpiggable Pipeline?

An unpiggable pipeline is a pipeline that is difficult to inspect internally with conventional in-line tools. There are numerous reasons why a pipeline may be considered unpiggable. Some of the most common causes include:

  • Over or under-sized valves.
  • The pipeline features a liner or is positioned vertically.
  • 90° elbows, unbarred tees, Y connections, etc.
  • Fabricated or mitre bends.
  • Small diameter pipes with tight bends.
  • No access, and more...

Each of these features can make it nearly impossible for conventional inspection tools to determine the condition of your pipelines. Fortunately, Russell NDE offers pipeline inspection services specifically for unpiggable pipelines. 

Your Source for Unpiggable Pipeline Inspection Services
