There are an estimated 900,000 electric utility steel transmission and distribution structures in North America alone. An increasing number of these structures are tubular steel poles. The degradation effects of corrosion can have a significant effect on the structural reliability of this important segment of our infrastructure. While the predictability of strength for a newly installed tubular steel pole is relatively easy to calculate, deterioration of these poles over time due to corrosion presents a different challenge to those calculations.
This standard is intended for use by electric utility personnel, contractors, inspectors, and those interested in the impact of corrosion on the needed strength capacity of a tubular steel pole structure used in transmission, distribution, and/or substation applications.
The purpose of this report is to communicate the effects of wildfires heat and combustion products on corrosion resistance, material properties, and mechanical integrity of power transmission infrastructure and to identify next steps to research, develop, and implement future asset integrity management actions for the power industry. The report addresses the following general topics.
A wildfire, bushfire, wildland fire or field fire is an unplanned, unwanted, and usually uncontrolled event in an area of combustible vegetation. Due to climate change, many locations in the United States and worldwide, such as Australia and even India, are subject to wildfires due to dry conditions during parts of the year.
Conductive and static dissipative floorings and coatings are designed to provide protection from electrical charges causing harm to work or products. This presentation is designed to familiarize you with the phenomenon of Static Electricity, how it is generated and its effects on industry. We will then discuss ways to alleviate or restrict problems associated with ESD by utilizing specialized conductive or static dissipative flooring and coating products. Specifically focused on the common conditions and design considerations required for a proper installation, including substrate requirements, grounding and strapping recommendations, and product selection criteria.
AC interference studies have become increasingly popular in an industry where shared right of ways have increased and there has been a better understanding of how AC interacts between pipelines and powerlines that are collocated with each other. While modeling software for AC interference studies have been developed since the 1990s, advancement in AC interference processes have occurred as more has been learned over the years. When performing an AC interference study there are three steps that need to be completed: field data collection, modeling, and mitigation design. Within this paper, we can compare a project from ten years ago to a project from today to understand the developments that have been made over the course of time to improve the way we develop our mitigation designs.
The corrosion profession, and the certified professionals who work in the industry, are committed to protecting people, assets and the environment from the effects of corrosion. Those tasked with delivering the technical expertise to society must conduct their work with the knowledge and understanding of the ethical principles expected and required of those professionals.
The NACE International Code of Ethics is discussed in conjunction with case studies and features real-life ethical violations of the NACE International Institute attestations. Frameworks for making ethical decisions are reviewed in this course along with the factors in the corrosion industry that can lead to unethical behavior.
The course is an online, self-paced course which should take no longer than 1.5 to 2 hours to complete. After you have purchased the course in the store, log into your AMPP profile and select “Online Courses” to begin the ethics course.

There are an estimated 900,000 electric utility steel transmission and distribution structures in North America alone. The majority of these structures were installed between 1950 and 1990. These structures are now an average of about 45 years of age. The age of these structures dictates an inspection and assessment procedure to determine the level of corrosion affecting the above-grade atmospherically exposed portions of this important segment of our infrastructure.
Prior to the publication of this standard, no industry practice existed to help electric utilities determine a prioritized listing of structures to be inspected or that described an inspection and assessment procedure to evaluate above-grade atmospheric corrosion problems.
