Is this statement true or false? Fiberglass and flexible plastic piping do not need
to have cathodic protection.
False.
Cathodic protection
a technique used to control the corrosion of a metal surface by making it the cathode of

protected to a more easily corroded "sacrificial metal" to act as the anode.
Fill in the blank to make the statement correct. Owners and Operators must keep
the most recent ___ records of cathodic protection testing.
