Test #6 Flashcards
(17 cards)
The top coat is primarily used to provide weather resistance.
True
Which surface preparation is called “Industrial Blast”?
NACE 8
Which of the following is the most common preventative measure for underground corrosion?
Cathodic Protection
Coatings increase the amount of current needed to achieve cathodic protection.
False
Cathodic protection polarizes the potential of the protected structure in the negative direction.
True
The TDS contains information about the health hazards of the coating.
False
Which of the following is the most common preventative measure for internal corrosion?
Chemical inhibitors
The primer coat is most often used to provide weather resistance.
False
Galvanic anode backfill serves what purposes?
Lower the circuit resistance Incorrect
Promote uniform consumption of the anode
Retain moisture
Corrosion inhibitors mitigate internal corrosion by stopping all chemical reactions.
False
Copper-Copper Sulfate reference electrodes are most commonly used to measure cathodic protection potentials in saltwater.
False
Cathodic protection is used to mitigate corrosion on the external surfaces of below ground structures.
True
Which organization certifies Coating Inspectors?
NACE
Mixed metal oxide, high silicon cast iron, and scrap steel are examples of galvanic cathodic protection system anodes.
False
Silver-Silver Chloride reference electrodes are most commonly used to measure cathodic protection potentials in saltwater.
True
The positive wire of a cathodic protection rectifier should always be connected to
The groundbed anodes
Mixed metal oxide, high silicon cast iron, and scrap steel are examples of impressed current cathodic protection system anodes.
True
