As public scrutiny toward pipeline integrity grows, regulators are frequently requesting that operators validate corrosion prevention data to prove that their assets are protected from failure. This means that in many situations legacy measurement techniques, are no longer sufficient and there is a need for validation to avoid ambiguity. This need for validation led to the development of Corrosion Service’s CPMP IR Free DC Coupon and the ZM3 Zero Resistance Ammeter. Used together, these tools provide a highly accurate indication of current flow to the pipeline that corresponds to corrosion protection levels, and validates the basic surface measurements typically gathered during pipeline surveys.
