Justification. Corrosion exists in every metallic substance to some degree
and in many cases to a severe degree. A corrosion protection program against severe
corrosion conditions must be justified on the basis of economy, necessity, and hazards.
Economy. The investment cost plus operating and maintenance costs of a
program should be less than the sum of the following:
Direct loss or damage costs resulting from corrosion of metal
b) Direct maintenance costs attributed to corrosion, including indirect
losses, such as leakage-loss of tank contents.
c) Increased costs for over design to allow for strength losses resulting
Costs of shutdown, power failures, labor losses, and other items.
Operational Necessity. Military facilities must be maintained in a state of
readiness at all times, with the importance and mission determining the degree of
necessity for corrosion protection.
where deterioration of structures, and containers and piping serving fluids or gases may
cause danger of fire and explosion.
Causes. For power plants, corrosion is caused primarily by oxidation,
galvanic action, or chemical attack. For more detailed information see MIL-HDBK-1003/6.
appropriate materials, use of metallic, organic, inorganic, or plastic coatings, and
cathodic protection systems. For additional detailed information, see MIL-HDBK-1003/6.
For description and design of cathodic protection systems, see MIL-HDBK-1004/10.
