AMPP TR21505-2022, Adverse Impacts of Wildfires on Power Industry Steel Structures

Product Number: AMPP TR21505-2022

Publication Date: 2022

$109.00

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.

Wildfire vulnerabilities and impacts
Materials effects for steel, coatings, and concrete
Power infrastructure risks and impacts
Asset integrity risk assessment guidance
Recommended industry actions
AMPP activities proposed

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.

AMPP TR21527-2023, Corrosion and Protection of Tank Cars in Crude Oil Service

Product Number: AMPP TR21527-2023

Publication Date: 2023

$109.00

This AMPP technical report describes the current state of protecting the interiors of tank cars transporting crude oil. This report is intended for and will benefit all stakeholders involved in the protection of tank cars transporting crude oil, including large fleet tank car owners, crude oil coating suppliers, tank car coating applicators, and crude oil shippers. The current state of protecting the interiors of tank cars transporting crude oil was developed by conducting surveys of various stakeholders. This report summarizes the survey results.

AMPP TR21540-2022, Correlating Qualitative Surface Profile Assessment Methods to Quantitative Methodology on Prepared Concrete Substrates

Product Number: AMPP TR21540-2022

Publication Date: 2022

$109.00

Coating/lining manufacturers and/or facility owners frequently specify cleaning and roughening of the concrete surface prior to product installation. The specifications may reference qualitative methods including visual assessments using comparison coupons or quantitative methods including surface profile depth measurements. However, prior to this Technical Report, there was no known data to inform a conversion between qualitative and quantitative methods. The outcomes of this Technical Report enable coating manufacturers, engineers, specifiers, and contractors to convert well-established qualitative methods to quantitative values based on an interlaboratory experiment. While current quantitative methods can measure up to 6 mm (250 mils), extremely rough concrete surfaces (exceeding ~1.5 mm, or ~50 mils) were not included in the experiment due to the inability to stabilize the instrument probe and obtain accurate data.

AMPP TR21544-2022, Corrosion and Mitigation Techniques for Fire Protection Piping Systems

Product Number: AMPP TR21544-2022

Publication Date: 2022

$109.00

This report explains different types of corrosion phenomena and contributing factors of corrosion that can occur in fire protection systems (FPS), such as water corrosivity, MIC, trapped air (wet systems), residual water (dry systems), and pipe weld corrosion. The basis for selection of corrosion mitigation strategies for corrosion mitigation and management of FPS are also discussed.

Corrosion that results in pipe leakage or obstruction is the most significant issue for owners of water-based FPS or fire sprinkler systems, in terms of both cost and system reliability. Corrosion damage/products and mineral deposits can impair the effectiveness of sprinkler systems, leaving facilities vulnerable to uncontrolled fire loss even though they are equipped with fire protection systems. This report describes practices that have been successful in mitigating FPS corrosion.
