Corrosion may severely affect the following functions of metals, plant
constituents must not be allowed to enter pipes, process equipment,
food containers, tanks, etc. to minimize the possibility of
Mechanical strength: Corrosion should
not affect the capability to withstand specified loads and its
strength should not be undermined by corrosion.
Dimensional integrity: Maintaining
dimensions is critical to engineering designs and they should not be
affected by corrosion.
Physical properties: For efficient
operation, the physical properties of plants, equipment and
materials such as thermal conductivity and electrical properties,
should not be allowed to be adversely affected by corrosion.
Contamination: Corrosion, if allowed
to build up, can contaminate processing equipment, food products,
drugs and pharmaceutical products and endanger health and
Damage to equipment: Equipment next
to the one which has suffered corrosion failure may be damaged.
Realizing that corrosion effectively blocks or impairs the functions
of metals, plants and equipment, appropriate measures must be adopted to
minimize the loss or efficiency of function.
