CORROSION PREVENTION AND CONTROL WORLDWIDE MATERIALS PERFORMANCE
The electric power utility industry commonly uses
galvanized steel for power transmission lattice towers
because it is known to be well-suited for service in most
atmospheric and underground environments and has a
long record of proven performance. This month, Materials
Performance features articles on corrosion in the power
industry as well as microbiologically influenced corrosion
(MIC). Assessing galvanized steel power transmission
poles and towers for corrosion is discussed in the feature
article, which starts on p. 24, and safeguarding the
foundations of these transmission towers with cathodic
protection is presented in the technical article on p. 30.
Preventing sewer corrosion and collapse by deactivating
bacteria is examined in the technical article on p. 44, and
using corrosion management to enhance mitigation of
MIC is covered in the technical article on p. 52.
