Joe Pikas will present “External Corrosion Direct Assessment” on January 27, 2022 at 8 a.m.

This class has the minimum required to be held and is continuing to accept registrations.


External Corrosion Direct Assessment (ECDA) is an industry-accepted practice for the determination of the integrity of pipelines.  This one-day training will present the four-step ECDA process for ascertaining the integrity of pipelines.  This webinar covers ECDA, Asset Integrity Management, Where to Dig, and concludes with Determining Areas of Concern.
