Micro-Tensile Testing of Chromium Coated Zirconium Cladding

Product Number: ED22-17270-SG

After the Fukushima accident there has been a large push globally for accident tolerant fuels (ATF) to increase the grace period during an accident, that is, the time during which operators may be able to avoid major consequences by undertaking mitigating actions. At Fukushima, the oxidation of the Zircaloy cladding produced hydrogen gas, that contributed to the failure of the primary containment. A concept for ATF is to coat zirconium-based cladding with chromium to inhibit the oxidation of the cladding and reduce hydrogen production.

Mildew Resistant Coatings for Ethanol Storage Tanks

Product Number: 51323-19329-SG

Author: Erik Dammen-Brower, Tony A Rook

Publication Date: 2023

$20.00

Mildew growth on commodity storage tanks is not a new issue within the industry and has been seen for years. However, ethanol storage tanks pose an interesting dilemma as the mildew growth on these tanks are especially aggressive and can completely deface the tanks again within months after being cleaned off. Historical knowledge of this mildew growth can be found when looking at distilleries.

Mineral Wool CUI Mitigation Improvements

Product Number: 51324-20798-SG

Author: Ricky Seto

Publication Date: 2024

$40.00

Mineral wool has been used for well over half a century as insulation to reduce heat loss, provide personnel protection, and protect against hearing loss. Corrosion under insulation (CUI) has been a major topic of interest as process facilities age and experience issues with corrosion, particularly on pipelines. Efforts have focused on reducing any effect of the insulation material on corrosion – e.g., by reducing chlorides, making the insulation hydrophobic, and recently, by upgrading the hydrophobic performance in terms of high-temperature resistance. The next step is to introduce a proprietary corrosion inhibitor within the mineral wool. If water does make its way to the metal substrate, the inhibitor will activate in contact with water to mitigate corrosion. This paper will present the CUI-mitigating efficacy of mineral wool with an integral corrosion inhibitor using the ASTM C1617 test modified for various chloride concentrations above the standard. The paper also discusses corrosion-inhibiting mechanisms, particularly how such mechanisms can modify the environment around steel substrates to mitigate factors that advance stress corrosion cracking.

Minimizing Health, Safety, and Environmental Challenges Associated with Traditional Blasting by Using Vapor Abrasive Blasting

Product Number: 41215-889-SG

Author: Bill Eliason

Publication Date: 2015

$20.00

Industries such as oil and gas, marine, cleaning and protective coatings face many changes and challenges from environmental, safety and other regulatory agencies. Most of these changes have to do with containment regulations and minimizing dust in open air blast environments. With these regulations now in place, contractors are looking for alternatives to traditional dry blasting.

Mitigating Stray Currents in 5G-Connected Metallic Structures: A Comprehensive Solution

Product Number: 51324-20830-SG

Author: Anil Kumar Chikkam; Michael Carone; Mehrooz Zamanzadeh; Aaron Ulmer

Publication Date: 2024

$40.00

As the telecommunication industry transitions to the fifth-generation mobile network, commonly known as 5G, the adaptation of this technology presents certain challenges that require careful consideration. While existing wireless communication infrastructures can be utilized for implementing 5G, one notable concern involves the potential for stray currents resulting from the installation of 5G equipment on pre-existing structures, particularly those made of metal. These unintentional stray currents have the potential to cause equipment damage, necessitating the development of a comprehensive solution to mitigate their occurrence. This paper focuses on addressing the issue of stray currents in 5G-connected metallic structures through the proposal of a comprehensive solution. The objective is to provide a preventive measure that ensures reliable and safe operation of 5G equipment without the risk of equipment damage caused by stray currents. The proposed solution aims to be universally applicable to all 5G equipment connections, providing a standardized approach to addressing this concern and facilitating the widespread adoption of 5G technology.

Mitigation Of Carbon Steel MIC Using THPS Enhanced By A Biofilm Dispersing Peptide In A Flow Loop With An Oilfield Biofilm Consortium

Product Number: 51322-17560-SG

Author: Di Wang, Tuba Unsal,Mazen A. Saleh, Mohammed D. Alotaibi, Magdy E. Mohamed, Sith Kumseranee, Suchada Punpruk, Tingyue Gu

Publication Date: 2022

MIC is a major threat to oil pipelines because it reduces the service life of pipelines and can potentially leads to catatrophes. Microbial communities commonly associated with pipeline corrosion include sulfate reducing bacteria (SRB), acid producing bacteria (APB), acetogenic bacteria and methanogens. In a field environment, SRB, APB and other microbes often live in a synergistic biofilm consortium. Sessile SRB are often the main culprit of MIC. They can utilize sulfate as the terminal electron acceptor and various carbon sources and elemental iron as electron donors. Corrosive APB biofilms are also a contributing factor in an acidic environment because they release H+ which is an oxidant.

Mitigation of Caustic Corrosion: Alloy and Process Considerations for High Velocity Thermal Spray Cladding

Product Number: MPWT19-14436

Author: Matthew Robert MacWatters and Iain Stuart Hall

Publication Date: 2019

$0.00

The use of High-Velocity Thermal Spray (HVTS) technology has been well adopted for sour conditions; particularly where low, or locally low, pH conditions result in corrosion and shell thinning. High alloy systems resistant to low pH or acidic conditions are effective at providing a metallurgical barrier, protecting the underlying substrate from material loss. Moreover, HVTS processes have also been employed for mitigating environmentally induced cracking (EIC) in sour service. This paper discusses the suitability and performance of modified HVTS alloys for service where high pH general corrosion or caustic cracking (CSCC) may occur. Extensive testing has been undertaken in both ambient and high pressure and temperature autoclave conditions to better understand material performance in caustic environments. While Nickel Alloy 200 and Monel 400 may be deemed appropriate based on traditional material selections, thermal spray process considerations in the material deposition and the impact of ancillary elements in the process stream, such as halides, render these alloys unsuitable. More complex Nickel alloy cladding systems are evaluated in this study with suitable material recommendations for remediation without the deleterious heat impact of welding or to protect surfaces where heat affected zones have been created and post weld heat treatment is problematic.

Mitigation Of CRU Heater Tube Carburization By Modified High Heat Transfer Ceramic Cladding Materials

Product Number: 51322-17831-SG

Author: Natalie Hana Frank, Iain Stuart Hall, Paolo Brunello

Publication Date: 2022

$20.00

Common materials employed in catalytic reforming unit tubes are typically resistant to carburization due to protective chromium oxide films, but under low excess oxygen conditions can become compromised and allow carbon penetration and carbide formation at the exposed surface. Embrittlement and material wastage as a result of these mechanisms causes premature failures, with production loss, in addition to shutdown maintenance and replacement costs. Carburization in this environment is simulated in this paper through a pack carburizing method designed to create an environment optimal for diffusing carbon in an ASTM 335 9Cr-1Mo tube material.

Mitigation of Elemental Sulfur and Iron Sulfide Under-Deposit Corrosion

Product Number: 51323-19423-SG

Author: Sherman Kung, Nolan Miller, Feras EI Yaakobi, Jeremy Moloney

Publication Date: 2023

$20.00

Production of highly sour oil and gas fields has increased recently, which introduces new challenges for
corrosion control. In recent years, some unexpected and unexplained pipeline failures have occurred,
resulting in complex investigations and laboratory corrosion performance testing studies to assess the
inhibitors that are applied in these environments. While some of these failures are due to cracking in
sour environments which are prevented by alternative material selection or different operation pipeline
maintenance, we were specifically looking at cases where chemical inhibitors could be used to mitigate
corrosion.
