Austenitic stainless-steel alloys are widely used as structural components in light water reactors (LWR) coolant systems, due to their passivity in high temperature water solutions. After initial passivation, subsequent development and dissolution rates of the protective film are very low. Nevertheless, metal cations and colloidal particles that are generated by superficial corrosion of structural materials, can be activated and generate radioactive isotopes that are responsible for radiation source as they circulate through the reactor core. Specifically, the radioactive 60Co, generated by neutron activation of the inactive 59Co (constituent of the naturally occurring Co), releases high-energy γ rays with a half-life of 5.3 years and is the main radiation source in boiling water reactor plants. Mitigating the incorporation of 60Co into stainless-steel oxide depends on understanding the phenomenon of oxide growth and development as a
function of the water chemistry employed, which involves thermodynamic and kinetic considerations.

Modified 13Cr (UNS S41426) (M13Cr) are advantageous as components for wellbores in oil and gas upstream units due to their high strength capabilities and tremendous corrosion resistance in sweet environments with minimal H2S levels. However, previous studies speculate disparities between an overestimation in the application limits for the 110 ksi grade material. Previous experimental results associate this to microstructural differences from varying heat treatments. The proprietary procedures used to manufacture, emphasize a lack of quality control among suppliers.

Upcoming Changes To NSF Drinking Water System Components Program (NSF 600) - No Need To Be Afraid

Product Number: 51322-18136-SG

Author: Steven P. Roetter

Publication Date: 2022

$20.00

In 1984 the US EPA issued a Request for Proposals to select a provider to privatize the approval of products and components used in water distribution systems across the United States. A team which was led by NSF International and included the American Water Works Association Research Foundation, the Association of State Drinking Water Administrators, the Conference of State Health and Environmental Managers, and the American Water Works Association was awarded the contract to develop the standard. In 1988, NSF/ANSI 61: Drinking Water System Components ― Health Effects was published as a result of the work of this team. This standard established minimum requirements for the control of potential adverse human health effects from products that contact drinking water and has been updated regularly since then to add testing criteria for additional contaminants and product types.

Upset Conditions In Anaerobic Digesters In Wastewater Treatment Plants Cause Degradation Of Protective Linings

Product Number: 51322-18235-SG

Author: Robert A. (Randy) Nixon

Publication Date: 2022

$20.00

Both mesophilic and thermophilic anaerobic digesters are currently being utilized to treat sludge derived from more than typical municipal sewerage sources. Wastewater treatment plants are accepting septage and sludge from food waste and industrial contributors routinely today. Receiving these other sources of waste which are extremely high in volatile solids is a source of significant income for the utilities.

EWPD of Saudi Aramco is the custodian of five large volume crude oil storage tanks with diameter of 106 m (348’) and 110 m (360’), where the crude oil is stored and transported from eastern region to western region. The tank which is being addressed in this paper is an API¹ 650 with floating roof. Its capacity is 1,013,000 barrels and its diameter is 110 m. This tank was built in 1978 on an oily sand pad and reinforced concrete ring wall. The inboard and sketch plates are 6.35 mm thick, and annular plates are 16 mm thick

Using Flexible Steel Pipe to Rehabilitate Aging Pipelines

Product Number: 51323-19013-SG

Author: David Gregory, Shawn Poworoznik

Publication Date: 2023

$20.00

This paper highlights a successful rehabilitation of a regulated steel line with flexible steel pipe. The pipeline resides under jurisdiction and was approved by both state and federal pipeline safety administrations. Upon completion, the rehabilitated system restored transmission while also reducing overall operating risk. Use of the flexible steel pipe allowed the operator to utilize a dual-containment design while also implementing real-time continuous annulus monitoring on multiple interfaces, effectively reducing risk to environment and local residents.

Using Galvanic Modeling and Aerosol Spray Testing to Understand How Changes in Salt Loading Can Impact Atmospheric Corrosion

Corrosion is not just a sustainment concern that impacts the availability and safety of critical structural assets; it is also a damage mechanism that should be considered during the initial design phase. By considering the corrosion process and associated preventive strategies during the design phase it is possible to reduce total ownership cost and improve equipment readiness. The Department of Defense spends more than $23 billion each year to control corrosion on aircraft and other equipment in its operations around the world.

Validating a Galvanic Corrosion Model under a Dynamic Electrolyte Droplet

As previously reported, the gap between electrochemical measurements for systems under bulk conditions and those under thin film layers of electrolyte is still important. Under thin film layers, it is not straightforward to take advantage of the typical three-electrode cell to electrochemically characterize a metallic surface under corrosion. Only a few localized electrochemical techniques are able to achieve measurements under thin films of moisture. It is important to bear in mind that the mechanism for corrosion under thin films is fully different from corrosion on bulk electrolytes and it is not valid to predict the behavior of the former system by extrapolating the latter.

Historically the corrosion condition and cathodic protection (CP) effectiveness of pipeline networks have been monitored by over-the-line surveys. Pipe-to-soil potentials and rectifier outputs are the major parameters measured, and for some pipelines a more intensive close interval survey is executed. Today test stations and more frequently rectifiers are equipped with remote monitoring devices which is shifting the industry towards the world of digitization. Unfortunately, external corrosion is still not fully under control.

More and more High Pressure High Temperature (HPHT) sour wells are operated worldwide. Challenging material selection is required for such severe operating conditions.^1,2 Very high strength materials, presenting yield strength above 896 MPa (130 ksi), are required for sustaining the pressure. Consequently, even a low amount of H₂S in the gas phase may lead to a H₂S partial pressure beyond the limit of 3.5 mbar (0.05 psi) established in NACE MR0175 / ISO 15156 standard.³ Indeed, both high yield strengths and partial pressures of H₂S contribute to a situation where the risk of Sulfide Stress Cracking (SSC) is high. The present paper is focusing on the SSC resistance of 130 ksi minimum yield strength material developed for covering such HPHT applications.

Water Based Flame Retardant Coating

Product Number: 51322-18184-SG

Author: Sachin Chavhan

Publication Date: 2022

$20.00

Fire is the biggest threat for the crews in aircraft, ships, submarines, and land vehicles. As a result of such threats there have been use of fire/flame retardants coatings increased exponentially to curb economic and social consequences of fire [1]. There are various types of coatings available to fight against the fire. Two classes of fire protection technologies are being used currently, 1) Fire retardant and 2) Fire resistant. Fire retardant coatings are passive fire protection coatings where such coatings can slow down the spread of the flames allowing more time for evacuation and firefighting. Fire resistant coatings typically inhibiting the flame penetration or do not ignite upon in contact with fire [2].
