Effect of Heat Treatment Temperature on the Corrosion Protection Performance of Thermal Sprayed Aluminum Coating

Product Number: 41214-844-SG

Author: KyungJin Park, SangKyu Ryu, MyoungHo Ahn

Publication Date: 2014

$20.00

In the present study, thermal effects on the corrosion behavior and corrosion protection performance of TSA coating were investigated using various electrochemical techniques. Heat treatment at higher temperature induces more cracks in the sealer and aluminum coating. Water and corrosive species (e.g., Cl-) penetrate through the cracks, resulting in corrosion of steel substrate.

Investigating the Effect of Trace O2 Concentrations on CO2 Corrosion Mechanisms

Product Number: 51324-20996-SG

CO2 co-produced in brine with crude oil is the governing corrodent in upstream oil and gas systems. A potential additional corrosive species that can be introduced through ingress is O2. Consequently, strict guidelines exist within the oil and gas industry to limit O2 levels in production environments, emphasizing the significance of understanding any associated corrosion risks. These guidelines require O2 concentrations to be as low as 20 ppb, however, there is little to no experimental evidence to support this limit. The aim of the research described herein was to advance the understanding of how trace O2 concentrations can influence CO2 corrosion mechanisms of bare steel at the acidic pH of 4. Elucidating these underlying mechanisms would enable more effective corrosion prediction, thereby enabling development of effective mitigation strategies, as well as establishing validity of the aforementioned “20 ppb” guideline related to O2 ingress. To accomplish these goals, controlled experiments were performed to test aqueous O2 concentrations up to 100 ppb on pipeline steel in a CO2 saturated 1 wt% NaCl brine at 1 bar total pressure. Various electrochemical analytical techniques, including LPR, EIS, and potentiodynamic polarization measurements were employed. The research reported herein is foundational for characterizing the impact of oxygen in CO2 corrosion environments, an ongoing research activity. This will contribute to the development of more reliable and sustainable corrosion control practices for industries experiencing CO2 corrosion which can be extendable to carbon capture and transmission systems.

Monitoring Localized and General Corrosion using Advanced Electrochemical Sensors

Product Number: 51320-14544-SG

Author: Timothy Duffy, Derek M. Hall, and Serguei, Margaret Ziomek-Moroz

Publication Date: 2020

In previous years, we have explored the use of electrochemical sensors for humidity and corrosion measurements inside of natural gas pipelines. Designed to operate in systems where a conductive aqueous phase is intermittent or unavailable, these membrane-based sensors utilize electrochemical techniques such as linear polarization resistance and electrochemical impedance spectroscopy to determine the environment’s corrosivity to the pipeline material. We now aim to explore this sensor’s performance and capabilities in more complex systems, specifically in environments that promote localized corrosion. Using the aforementioned electrochemical techniques, along with electrochemical noise and cyclic voltammetry, we probe and monitor localized corrosion and general corrosion of X65 steel in the presence of inorganic pitting agents. Experiments are conducted in both aqueous and nonaqueous environments. The additional functionality increases the quantity and quality of corrosion data from these sensors, offering to internal corrosion-monitoring programs a more complete picture of real-time corrosion within their natural gas pipelines.

NACE SP21427-2019 “Detection and Mitigation of Stray-Current Corrosion of Reinforced and Prestressed Concrete Structures”

Product Number: 21427-SG

Publication Date: 2019

$179.00

HISTORICAL DOCUMENT. This NACE International standard practice establishes the general principles to be adopted to minimize the effects of stray current corrosion caused by direct current (DC) and/or alternating current (AC) from external sources on steel reinforced concrete (RC) and prestressed concrete (PC) structures or structural elements. The standard practice offers guidance for the design of concrete structures that may be subject to stray-current corrosion; the detection of stray current interference; the selection of protection measures; and the selection of mitigation methods.

NACE SP21427-2023, Detection and Mitigation of Stray-Current Corrosion of Reinforced and Prestressed Concrete Structures

Product Number: NACE SP21427-2023

Publication Date: 2023

$109.00

This standard practice describes appropriate prevention and mitigation measures that can be applied to RC and PC structures that are, or can be, exposed to stray-currents from external sources in order to minimize or eliminate stray-current corrosion. This standard practice addresses only steel corrosion related issues, and does not deal with issues of safety and hazards to people or structures associated with DC and AC voltages; these are covered in national standards and regulations, such as EN 50443 and EN 50122-1.
