The objective of this work was to compare irradiation-assisted stress corrosion cracking (IASCC) growth behavior in simulated pressurized water reactor (PWR) water with pH maintained with LiOH versus KOH. The U.S. nuclear industry is considering changing PWR primary water chemistries to use KOH in place of LiOH, as a means to ensure a stable supply chain and secure cost savings. This experiment will specifically investigate the impact of these alkali ions on the crack growth rate (CGR) and to examine the crack morphologies generated by the CGR experiment.

The use of carbon steel pipelines lined or clad with corrosion resistant alloys (CRAs) is increasing in the O&G industry. These pipelines combine the mechanical properties of carbon steel with the corrosion resistance of CRAs. Some CRAs such as AISI 316L (UNS 31603) are not pre-qualified according to ANSI/NACE MR0175/ISO 15156 part 3. The potential for corrosion and cracking of carbon steel in some applications can require a CRA liner/clad layer to resist corrosion but this can introduce the possible risk of stress corrosion cracking of some CRAs.

Fracture mechanical specimens of the compact tension (CT) type are normally used in tests that study stress corrosion crack (SCC) growth rates (CGR). Normally, the width, W, is twice the thickness, B (W=2B), and B for common specimen sizes is 12.5 or 25 mm. The specimen size can be changed by scaling its dimensions.

The Effect Of Strain On Surface Residual Stress In Alloy 600 Tensile Specimens

Nickel based Alloy 600 is used within the nuclear industry in structural components due to its good mechanical properties and general corrosion resistance, however upon exposure to primary water environments at elevated temperatures it can be affected by Primary Water Stress Corrosion Cracking (PWSCC). Nickel Based Alloy (NBA) susceptibility to PWSCC is dependent on a number of factors that include material type, condition and microstructure, as well as fabrication method, and can be investigated by uniaxial initiation testing in a primary water environment, where specimens are held at constant load under an elevated temperature.

Maintaining the integrity of oilfield equipment is essential to its safe operation and to maximize the efficiency of production. The integrity of oilfield equipment can rely on material selection and control of conditions, however, it is commonly maintained by the applications of chemical corrosion inhibitors (CI). Prior to use, these chemicals must be shown to perform as desired under the field conditions in question. To achieve this, chemicals are often evaluated using robust laboratory-based screening studies to identify potential candidates.

Parts produced via additive manufacturing (AM) are being adopted broadly among many industries and
used in an array of applications. AM parts are attractive to these industries for several reasons. Complex
geometries that cannot be manufactured using traditional, subtractive methods can be produced
additively.

The Effects Of Different Blast Abrasives On The Performance Of Liquid-Applied Epoxy Pipeline Coatings

Product Number: 51322-17806-SG

Proper surface preparation to create sufficient adhesion of a coating over the substrate is fundamentally important in the long-life performance of a protective coating. Abrasive blast cleaning provides a fast and well-established method of surface preparation, which utilizes energy generated by an air supply to deliver a mass of abrasive particles at certain speeds and volumes to impact the steel resulting in a cleaned surface. The method not only cleans the surface to remove rust, scale, paint, and similar contaminations, but also roughens the surface to produce mechanical and chemical adhesion for a coating. Therefore, abrasive blasting is the preferred method for preparing steel for the application of high-performance coatings and routinely used for achieving the required surface conditions prior to a coating work.

The drive towards renewable energy, requirement for reduction in fossil fuel consumption and emission of carbon dioxide has received substantial attention from governments and researchers worldwide during the last few decades [1]. The exploration of renewable sources of energy has been grouped into wind, geothermal, tidal and solar energy. Solar energy has shown great promise due to the abundant amount of energy reaching the Earth [2, 3]. Electricity generation from solar irradiation can be achieved by photovoltaic (PV) and photothermal conversion [4].

The Evolution of Thermoplastics as a Solution to MIC and Oxidative Corrosion Issues

Product Number: 51324-20978-SG

Author: Bryan L. Hutton

Publication Date: 2024

$40.00

Corrosion costs our industrial industries billions of dollars every year. Facilities focus on metallic solutions such as alloys, protective coatings, and corrosion prevention techniques to combat the issues. However, thermoplastics continue to grow as a sound engineering solution in many corrosive environments such as offshore, downstream processing, Chlor-alkali, mineral processing, semiconductor, metal pickling, pulp and paper, and many other emerging markets. Thermoplastics are inherently resistant to corrosion, and technology continues to create more robust, longer-lasting, more sustainable technologies. AMPP brings our members together to advance technical and practical corrosion prevention and control expertise. This paper will provide a comprehensive overview of several thermoplastic solutions, construction standards, and how they are addressed in the ASME B31.3 standards. The paper will help the reader understand the physical characteristics, polymer chemistry, and typical application range for several thermoplastics using industry standards such as ASME B31.3, ASME RTP-1, ASTM standards, and AWS. Thermoplastics may not be applicable in every application, but many support environments can take advantage of the increased service life, corrosion resistance, and lightweight thermoplastic materials. The paper will set the stage for our members to see applications where they can solve their corrosion issues like Potable/DI/RO water, sodium hypochlorite, sodium hydroxide, brine, sulfuric acid, phosphoric acid, sodium chloride, chlorine dioxide, nitric acid, and hydrochloric acid. Proper material selection and methodology combined with sound fabrication and installation techniques will be addressed to help our members find qualified support for their facilities. The industry needs thermoplastic guidance to build confidence. Our engineers, such as I (a chemical engineer), must be better trained in the accredited education system on thermoplastics, polymer science, or material selection techniques. True to the purpose of AMPP, this paper is built on the premise of providing AMPP members with the knowledge and resources to ensure high-performance materials are used to develop and maintain sustainable infrastructure.

The History Of Hydrogen Induced Stress Cracking (HISC) Failures Of Duplex & Super Duplex Stainless Steels (DSS/ SDSS) Due To Cathodic Charging And The Potential For Improvement In HISC Resistance

As long ago as 1973, design codes1 considered the possibility of hydrogen embrittlement due to CP. Between 1986 and 1995^2-4 the failure of DSS fasteners subjected to CP were reported. These were associated with high ferrite levels in the steel (approximately 70%) combined with precipitation hardening at 475°C to give the high levels of strength desired for fastener applications. At the same time, the susceptibility of DSS welds to hydrogen embrittlement had been reported5. Just like the fastener failures, the hydrogen cracking of welds was associated with high ferrite levels (70%), highly restrained joints and in the case of welds, high levels of diffusible hydrogen.
