Six Degrees of Isolation: The Effects of Operating a Pipeline Without Isolation

Isolation plays a vital piece in the fight against corrosion. However, isolation in a cathodic protection system is not always used, isolation kits may malfunction, and/or an isolating kit may be found to not be isolating and might be replaced by a non-isolating gasket. What effect on the piping system, personnel and costs does this have?

This webinar will delve into the cause/effect analysis when isolation is not part of the cathodic protection package (whether intentional or unintentional). The primary effects are:

· Increased electrical costs

· Increased likelihood of hydrogen induced corrosion

· Potential for electrically induced coating disbondment

· Increased potential for stress corrosion cracking

· Greater potential for current to stray from pipeline to unintended targets

· Potential for unsafe electrical exposure for personnel
