ISBN: 9335 2017 CP

Author: Derek Horton

Publication Date: 2017

AMPP SP03-30-2022, Treatments for the Protection for Metal Parts of Service Stores and Equipment Against Corrosion

Product Number: AMPP SP03-30-2022

Publication Date: 2022

$109.00

The original Def Stan was adopted as an AMPP standard under the provisions of the AMPP Standards Committees Operating Manual Procedures for Conversion of Government Agency Standards.

This standard is a guide to corrosion protection against atmospheric corrosion and covers all aspects from the basic mechanisms of aqueous corrosion, though a summary of the differing types to a detailed review of aspects of atmospheric corrosion. It concludes with a detailed survey of the methods of control against corrosion and a focused description of the particular methods of corrosion protection for different metals and alloys.

AMPP SP21554-1-2023, Environmental Severity Monitoring Site Selection Guide

Product Number: AMPP SP21554-1-2023

Publication Date: 2023

$109.00

This document is to serve as a guide towards location selection criteria for researchers measuring the risk of environmental corrosion. It is not a set of instructions for how to build a standardized test site with well-defined exposure conditions. Rather, the goal of this document is to provide guidance on how to select test locations when pre-installed exposure racks or defined test areas are not established. While this document is part of a group of standards designed to quantify environmental severity for the aerospace and defense industry, this standard is intended to be applicable to all industries.

AMPP TM21449-2021, Continuous Measurements for Determination of Aerospace Coating Protective Properties

Product Number: AMPP TM21449-2021

Publication Date: 2021

$109.00

The purpose of this standard Test Method is to provide guidance on the testing and evaluation of coatings for aerospace applications. This Test Method has been developed for use by researchers, manufacturers, and organizations responsible for the manufacture, specification, and use of corrosion protective coatings for aerospace structures. The Test Method details measurement techniques to continuously monitor the combined environmental and mechanical effects that drive coating degradation in laboratory tests. While for many industries, judgements of coating performance may be primarily aesthetic, this Test Method describes direct, continuous measurements of coating degradation processes that are important to aircraft structural integrity.

An Approach to Assess Environmental Severity Categories Using Corrosion Sensors

Product Number: 51324-20739-SG

Author: James Dante; Erica Macha; Andrew Keller; Michael Hartnett; Shengyen Li

Publication Date: 2024

$40.00

This work examines data from a multi-year, large deployment of corrosion sensors in a variety of locations representing a range of corrosivity severities. The corrosion sensors used in this work measure atmospheric parameters including relative humidity and temperature in addition to conductance of the electrolyte formed by salt deposition. First, a rudimentary model is developed based on a small sampling of corrosion sites to demonstrate a means by which environmental parameters (RH, temperature, and conductance) can be viewed to assess environmental severity. The model is simplified and applied to a broader number of sites to determine its viability for predicting severity. Results are compared to current Air Force severity rankings and literature data separately.

An Integrated Probabilistic Approach to Predicting the Occurrence of Atmospheric Stress Corrosion Cracking of Dry Storage Canisters

Product Number: 51323-18893-SG

Author: Aaron J. Stenta, Brandon R. Rollins, Gerald Young, Narasi Sridhar, Ramgopal Thodla

Publication Date: 2023

$20.00

Spent nuclear fuel (SNF) is currently stored in stainless steel dry storage canisters (DSCs) contained within concrete cask systems with passive ambient air cooling. These systems are emplaced, either horizontally or vertically, at independent spent fuel storage installations (ISFSIs), located at utility reactor sites. The ambient air introduces moisture, aerosolized salt particles, and dust to the canister surfaces. The composition of the aerosols depends on geographical factors, such as proximity to the ocean,
industrial area, rural areas, and transportation corridors that use road salt for winterization.

ANSI/NACE TM0416-2023/ISO 22858:2020, Corrosion of metals and alloys — Electrochemical measurements — Test method for monitoring atmospheric corrosion

Product Number: ANSI-NACE TM0416-2023-ISO 22858-2020

$140.00

The purpose of this document is to provide instructions on the use of electrochemical sensors for monitoring atmospheric corrosion. These sensors are used to measure thin film electrolyte conductance, corrosion current or coating condition over long periods. This method permits the instantaneous evaluation of corrosion current that can be related to specific environmental conditions in real time. The instantaneous corrosion current measurements are not accessible using electrical resistance sensors or mass loss techniques. The technology described in this document complements other standard techniques for assessing atmospheric corrosion such as mass loss coupons, electrical resistance sensors or coated test panels (see ISO 8407 and ISO 4628-8). These continuous records of material condition can be useful for studying atmospheric corrosion, evaluating materials or managing assets.

Atmospheric Corrosion Detection And Management With AI

Product Number: 51322-18087-SG

Author: Eric L. Ferguson, Steve Potiris, Marco Castillo, Toby F. Dunne, Suchet Bargot

Publication Date: 2022

$20.00

External corrosion on offshore O&G platforms is one of the biggest threats to asset integrity and its management is a large operational expense. Many operators now implement risk-based assessment (RBA) programs where all equipment is assessed periodically with the aim to reduce operational costs while maintaining integrity. Regulatory codes for offshore platforms in the GoM require a visual inspection of all pressure equipment and piping every five-years. In practice, this can equate to approximately 20% of equipment being inspected per year on a large-sized offshore platform (i.e., a topside weight of around 10,000 tons), with a rolling five-year inspection plan to balance the inspection workload evenly through time.
