Author: A. Philipp

Publication Date: 2023

$20.00

Different solutions are provided to the industry to avoid corrosion in demanding environments. It can be
done by optimization of process conditions, coating, and cathodic protection, for example. Another way
is to select material grades like stainless steel, nickel alloys, or zirconium and titanium to improve the
equipment’s lifetime.

Long-Term Aging Behavior Of Cold-Worked Alloy 690 In Simulated PWR Primary Water

Product Number: ED22-18358-SG

Author: Ziqing Zhai, Matthew J. Olszta, Mychailo B. Toloczko

Publication Date: 2022

$20.00

Alloy 690 has been utilized since the late 1980s as a replacement for Alloy 600 in pressurized water reactors (PWR) pressure boundary components due to laboratory data indicating higher resistance to stress corrosion cracking (SCC). Although to date no SCC incidents have been reported on Alloy 690 components in service, the growing interest of extending the operation life of PWRs beyond 60 or even 80 years has raised concerns for the potential occurrence of long-range ordering (LRO) in Alloy 690 and its compatible weld metals.

Long-Term Case Studies Of Cathodic Protection Along The Texas Gulf Coast

Product Number: 51322-17734-SG

Author: Stephen W. Foster, Kyle Myers

Publication Date: 2022

$20.00

Managing aging reinforced concrete infrastructure is a complex and capital-intensive task, particularly in harsh marine and coastal environments. Corrosion from saltwater, coupled with wet and dry cycles, are particularly problematic for long-term durability of reinforced concrete. The Gulf Coast presents a challenge for maintaining service life of concrete structures that are exposed to high levels of chlorides, either by direct contact with salty or brackish water or by indirect contact with salt spray. Chlorides induce corrosion of the steel reinforcement which initiates cracking and spalling of the concrete, reducing the service life of the structure.

Long-Term Corrosion Behavior Of Borated Stainless Steel In Simulated Spent Fuel Pool Environment

Product Number: ED22-17318-SG

Author: Daehyeon Park, Yunju Lee, Junhyuk Ham, Seung Chang Yoo, Kiyoung Kim, Donghee Lee, Yongdeog Kim, Ji Hyun Kim

Publication Date: 2022

Most of countries store spent nuclear fuels in pools (SFP) which are built in nuclear power plants. As number of nuclear power plants and corresponding number of spent fuels increased, density in SFP storage rack also increased. In this regard, maintain subcriticality of spent nuclear fuels was raised as an issue and BSS was selected as structural material and neutron absorber for high density storage rack. BSS has better mechanical properties than other neutron absorbers which were fabricated based on aluminum alloys.

Long-Term Cost Saving By Using High Alloyed Stainless Steel In Seawater Coolers

Product Number: 51322-17544-SG

Author: Jonas Höwing

Publication Date: 2022

$20.00

Copper alloys such as copper nickel (CuNi) and Admiralty Brass (CuZn) are often successful material selections for seawater coolers. The copper alloys successes in these highly corrosive environments can be attributes to the ability of copper to form a protective scale, thus stopping corrosion of the material. On copper alloys in seawater, the protective scale formed comprises a mix of cuprous oxide (Cu2O), copper oxide (CuO) and copper hydroxy chlorides.

Long-Term Performance Of Alloy 690 In LWR Environment

Product Number: ED22-17284-SG

Author: Bogdan Alexandreanu, Yiren Chen, Xuan Zhang, Wei-Ying Chen

Publication Date: 2022

$20.00

Nickel-based Alloy 690 and the associated weld Alloys 52 and 152 are typically used for nozzle penetrations in replacement heads for pressurized water reactor (PWR) vessels, because of their increased resistance to stress corrosion cracking (SCC) relative to Alloys 600, 82, and 182. Many of these reactors are expected to operate for 40-80 years. Likewise, advanced water-cooled small modular reactors (SMRs) will use Ni-Cr alloys in their primary systems and are expected to receive initial operating licenses for 60 years.

LoRaWAN – The Future of Remote Sensing Technology

Product Number: MECC23-19983-SG

Author: Mitchell Gribi

Publication Date: 2023

$20.00

We live in a data driven world where technology is constantly evolving and making our lives easier, but even with this progression, industrial facilities are still struggling with the lack of reliable and sufficient data. LoRa has the capability to affordably expand remote sensing technologies in industrial applications, thereby improving operational efficiency, automating processes, and improving safety. With several different types of sensors available, and many more being created every year, LoRa is set to become the industry standard for the Industrial Internet of Things (IIoT).

Low Dose Novel Additive Synergist/Enhancer for Imidazoline Based Oilfield Chemical Products

Product Number: MECC23-20179-SG

Author: Yolanda De-Abreu; Gabriela Garcia; Jeremy Moloney

Publication Date: 2023

$20.00

Throughout the oil and gas industry, carbon steel continues to be the material of choice for most downhole production tubulars and pipelines. Given the environment of typical oilfield operations, comprehensive integrity management programs are followed to guard against the threats of internal corrosion and material degradation of such assets. Although there are various corrosion mitigation options available, the application of corrosion inhibitor chemical products is commonplace given their relative ease of use and cost effectiveness.

Based on US Energy Information Administration (EIA) Annual Energy Outlook (AOE) predictions, by 2050, the US nuclear capacity for electricity generation may decrease to ~ 80% of 2021 levels, Moreover, by 2050, nearly 50% of the existing US LWR fleet will be within 10 years of 80 years of operation suggesting that without a Life Beyond 80 (LBE) plan and limited new builds and advanced reactors, the US could lose up to 50% of its nuclear capacity resulting in a ~30-gigawatt (GW) capacity shortage by 2060. These numbers could change dramatically depending upon oil and gas supplies, and the growth of renewables.

Making It Last: An Interactive Lifecycle Calculator for Selecting Water Tank Coatings

Product Number: 51323-19199-SG

Author: Cameron Walker, Jennifer Gleisberg

Publication Date: 2023

$20.00

A life cycle costing analysis (LCCA) is the process of compiling cost estimates for each coating system option in combination with the expected life span of each of those options. In general terms, the lowest cost per year of service is the most economical choice. This LCCA process can be paired with an environmental impact analysis to evaluate the sustainability considerations of managing the water tank asset. One of the most commonly addressed factors in an environment life cycle assessment is a calculation of the greenhouse gas emissions associated with a process, presented in equivalent CO2 emissions.
