L52044 Effects of Operating Practice on Crack Dormancy and Growth
Authors: Zheng
Published: August 2023

This report describes the output of two phases of the research contract on �Effects of Operating Practice on SCC Crack Growth�, GRI-05/8668, submitted to PRCI in August 2002 (Phase I) and in July 2003 (Phase II).

The objective of the first phase of the work was to identify, through literature survey, a correlation model that relates the crack growth rate in low-pH or in high-pH environments to the deformation rate of the line pipe steel. The objective of the second phase of the project was to experimentally validate the correlation model(s) identified in Phase I. The ultimate goal of this work is to define the critical loading condit ions necessary for SCC so that operating practices can be assessed for the purpose of eventual avoidance of SCC.

It is also hoped that such a deformation-rate-based model can provide insight for understanding the transition between �active� and �inactive� (or dormant) states of the cracking that is often observed in laboratory SCC tests. Understanding the causes for dormancy of stress corrosion cracks and the mechanism(s) of crack reactivation has significant practical implications. Service life is extended if conditions of dormancy can be maintained and conditions of growth or reactivation can be avoided.

L51502 Investigation of Side-Drain Potential for Cathodic Protection of Bare Pipelines
Authors: Barlo Thomas
Published: August 2023

The objectives of this research are:

- To determine the relationships between ground-level potential distribution and net cathodic current picked up on a bare pipeline, and

- To verify those findings in the field.

The research was conducted in two tasks. In Task 1, computer code calculations were performed for selected conditions to examine the relation between ground-level potentials and the current direction and magnitude at the pipe surface for cathodic protection current impressed on a bare pipeline from a distributed-anode, or remote-anode system. In Task 2, measurements were made on a 20-inch diameter bare pipeline in Charleston, West Virginia, and a 10-inch diameter bare pipeline near Hurricane, West Virginia to verify the computer code calculations.

PR-335-143705-R01 Study on Reliability of In-ditch NDE for SCC Anomalies
Authors: Riccardella Scott
Published: August 2023

Pipeline operators are increasingly finding pipeline degradation in the form of crack-like defects associated with stress corrosion cracking and are challenged in selecting and employing nondestructive examination techniques that can reliably determine the maximum depth and axial depth profile of these anomalies. This information is essential in determining whether the line is fit for service and for how long; which areas require repair; what repair methods may be deemed acceptable; and whether in-line inspection was successful in detecting and prioritizing anomalies.

This work further investigates and quantifies the capabilities and limitations of different nondestructive examination methodologies that are typically used and/or identified as feasible for the characterization of crack-like features. The objective of this project was to develop and implement a process to evaluate the applicability, accuracy, and sensitivity of different nondestructive examination methodologies in sizing stress corrosion cracking anomalies. This report outlines the nondestructive examination methodologies selected, the test processes and protocols used, the crack truth verification processes used, and the analysis of the final results.

PR-685-184506-R04 Potential Monitoring Techniques and Technologies for Real Time Rainfall and Flooding
Authors: Budzich Jeffrey
Published: August 2023

Systems to alert pipeline operators of existing or impending flood events of concern are important tools as operators work to protect infrastructure at crossings of concern. A critical return period flood alert allows operators to take pre-emptive actions that may reduce consequences involved in major flood events. Gages are valuable tools for collecting data and information about discharge. Physical in-waterway gages include reference gages, crest stage gages, and recording stage gages. For recording stage gages, data can be transmitted electronically and limit the need for site visits. Online, or 'virtual' gages, such as National Oceanic and Atmospheric Administration's high-resolution National Water Model and the National Weather Service Weather Prediction Center, are an alternative to using gages to collect data, as they cover larger areas and are typically less expensive than installing, maintaining and operating site-specific gages.

GRI-05-0074 Engine Testing of Optimized Nozzles for High Pressure Fuel Injection
Authors: Olsen Daniel , Quillen Kris
Published: August 2023

High-pressure fuel injection has become an important retrofit technology for lowering emission and fuel consumption in large bore natural gas engines. As emissions regulations become more stringent, the need for further reductions in pollutant emissions and fuel consumption is apparent. One aspect of high-pressure fuel injection where there is still room for improvement is the nozzle. The nozzle can both redirect and accelerate the fuel jet as it enters the cylinder. In this work, various new supersonic nozzle designs are experimentally evaluated. Experimental results for two different fuel injection systems are presented. The two systems are differentiated by the supply pressure. One operates at 275 PSIG and the other at 500 PSIG. Experimental evaluation is on a Cooper-Bessemer GMV-4TF large bore natural gas engine. Nozzle comparisons are made against stock Hoerbiger nozzles.

IPC-04-01 Concepts and Production Results of Heavy Wall Linepipe in Grades up to X70 for Sour Service
Authors: Leissem Andreas , Schwinn Volker , Poepperling Rolf K. , Jansen Jean-Pierre
Published: August 2023

This paper summarizes the main mechanism and influencing factors for Hydrogen Induced Cracking. The evolution of HIC test requirements over nearly 30 years for linepipe intended for sour service is reviewed. Some typical examples of the requirements for sour service pipe production at Europipe (formerly Mannesmann) developed over the past 20 years and the details of trial production of sour service pipes in grade X 70 with 30 mm wall thickness are presented. However, with the steadily increasing demands, it becomes progressively more difficult to fulfill the before mentioned standard test conditions. In those cases where the overall profile of requirements (strength, toughness) cannot be consistently achieved, fit-for-purpose testing methods are currently emerging. As an example, the results of a pipe order, where the fit-for-purpose approach has been used to qualify the pipe for a special project, will be described.

Published: August 2023

The project focuses on developing glass fiber reinforced polymer (GFRP) composite pipes including a range of joining systems. A few of the many advantages of GFRP composite pipes are their non-corrosiveness, magnetic transparency, and high strength-to-weight ratio. As a part of this project, GFRP pipes and joints were designed, manufactured, and evaluated under static loads. Emphasis was placed in the evaluation of stress-rupture (burst pressure) of GFRP composite pipes that could withstand internal pressures as high as 5000 psi. The report also includes the design and testing of high-pressure composite joints for these pipes. In addition, the report discusses the use of Ground Penetrating Radar (GPR) for successfully detecting the FRP pipes under buried conditions. The report also includes the detection of gas leakage from buried pipes using mass spectroscopy.
DTPH56-15-T-00004 Framework for Verifying and Validating External Leak Detection Systems on Pipelines
Authors: Bussiere Matthew , Smith Shawn , Bussiere Stephane
Published: August 2023

A leak detection evaluation framework has been developed for use pipe pipeline operators to identify and evaluate candidate external leak detection systems intended for possible deployment on onshore transmission pipelines and assist operators in making an informal technology selection. The framework focusses on leak detection systems that are deployed or that operate external to the pipeline. Such systems are reportedly capable of detecting small releases that fall below the detection threshold of traditional leak detection systems, such as computation pipeline monitoring systems, and can therefore serve to complement existing leak detection infrastructure by extending the overall detection range.

Develops a quantitative assessment of time-dependent threats, with a focus on vintage onshore gas transmission pipelines. Characteristics for the vintage pipeline system were established in terms of diameter, wall thickness, service conditions, grade and toughness, and pipeline designs typical of this system identified. Analyses to qualify mean-time-between-failure and related inspection intervals were performed for these typical vintage pipelines addressing time-dependent degradation and possible failure due to corrosion, fatigue, and stress corrosion cracking. Hydrogen embrittlement also was considered although not in regard to mean-time-between-failure. Results developed were used to quantify pipeline life as a function of the sizes of defects that have caused incidents in vintage pipeline systems.

DTRS56-04-T-0005A Radiant Heat Attenuation by Clothing and Human Tolerance to Radiant Heat
Authors: Raj Phani K.
Published: August 2023

A series of tests involving the exposing mannequins clothed with normal civilian clothing to a 10 ft. x 10 ft. LNG pool fire was conducted. Both single layer clothing and double layer clothing were used. The radiant heat flux incident outside the clothing and incident on the skin covered by clothing were measured using wide-angle radiometers, for durations of 100 s to 200 s (per test). The levels of heat flux incident on the clothing were close to 5 kW/m2. The magnitude of the attenuation factor (AF) (ratio of the outside radiant heat flux to that on the skin) was calculated. It is seen that AF varies between 2 and higher for ordinary cotton and polyester clothing (of thickness 0.286 mm to 1.347 mm). Values as high as 6 have been measured for clothes of thickness of 1.347 mm.

Tests similar to the above were conducted to determine the attenuation factor when a single or multiple sheets of newspaper are interposed in front (about 5 cm) of the radiometer. Singe sheet newspapers reduce the heat flux to the radiometer by a factor of about 5 at a heat flux level of 5 kW/m2. Double sheets reduce the heat flux intensity by a factor of almost 8! The magnitude of the AF for newspaper sheets depends on the magnitude of the heat flux and thickness. It decreases linearly with increasing heat flux values and increases linearly with an increase in thickness.

PR378-173601-Z01 Effect of Pressure Fluctuations on the Growth Rate of Near-Neutral pH SCC
Authors: Chen Weixing
Published: August 2023

This report summarizes the work completed in PRCI SCC-2-12A project: The Effect of Pressure Fluctuations on the Growth Rate of Near-Neutral pH SCC, which is Phase 3 of the work on the same subject of investigation. The following insights from the current phase of the PRCI SCC-2-12A project are thought to be the most important:

- Near neutral pH crack initiation is pressure-fluctuation dependent. Severe pressure fluctuations accelerate the fracture and spallation of mill scale on the pipeline steel surfaces, making it harder to initiate SCC cracks from the bottom of pits that are developed at flawed mill scale sites. On the other hand, the presence of a primer layer before application of the protective coating preserves the mill scale on the pipe steel surface and promotes crack initiation.

- The early-stage crack growth primarily features crack length extension on the pipe surface but limited crack growth in the depth direction. Three different mechanisms of crack length extension have been identified, including that determined by the geometry of coating disbondment, a chaotic process of crack coalescence, and the ability of existing cracks to induce further crack initiation and growth. This latter process is pressure-fluctuation sensitive.

- A complete set of equations governing crack growth in Stage 2 has been established based on experimental specimens with surface cracks under mechanical loading conditions realistic to pressure fluctuations during the operation of oil and gas pipelines.

- The contribution to crack growth by direct dissolution of the steel at the crack tip has been determined, which has been found to be crack depth-dependent and pressure-fluctuation-sensitive. Gas pipelines operated under high mean pressure show higher rates of dissolution.

- The severity of crack growth and the accuracy of the predictive model can be significantly affected by crack tip morphology, either sharp or blunt, and this would yield different threshold values for Stage 2 crack growth and therefore different lengths of remaining life.

- Full scale testing was performed and has validated the crack growth models contained herein.

- The PipeOnline software has been revised to incorporate the new experimental results obtained from the current PRCI SCC 2-12A project. This PipeOnline software was previously developed from the two earlier phases of the PRCI project.

Authors: Adhitama Amru Bangkit , Kurniawati Kurniawati , Masnita Yolanda
Published: August 2023

This study delves into the interplay between Perceived Crowding (Crowd) and its impact as a mediator on Purchase Intention, Customer Satisfaction (SAT), and Word of Mouth (WoM). Specifically, it examines the role of crowd perception as a deciding factor for selecting a restaurant, thereby influencing overall consumer satisfaction. The research comprises a sample of 100 respondents, spanning multiple generations. The data analysis technique employed is Structural Equation Modeling (SEM). The findings of this study underscore the significant mediating role played by Perceived Crowding (Crowd) on the relationship between Purchase Intention and both Customer Satisfaction (SAT) and Word of Mouth (WoM). This insight suggests that the presence of crowds acts as a crucial factor in shaping customers' purchase decisions, overall satisfaction, and likelihood to engage in positive word-of-mouth referrals. Interestingly, the research highlights the distinct behavior of the millennial generation and Generation Z. These younger demographics exhibit a penchant for aligning with current trends. Even when faced with long queues at a food establishment, they display a willingness to wait, suggesting a correlation between crowd perception, purchase intent, and consumer behavior in these generational groups. This study underscores the importance of understanding the dynamics of Perceived Crowding and its role in influencing consumer behavior, particularly among the younger generations. It sheds light on the complex interrelationships between Purchase Intention, Customer Satisfaction, and Word of Mouth, offering valuable insights for businesses in the food industry seeking to optimize customer experiences and harness the power of positive word-of-mouth promotion.
Role of Self-Regulatory in Luxury Brands’ Social Media Advertising
Authors: Kwon Eunseon , Ma Liang
Published: August 2023

Luxury brands are increasingly using social media messages as their ads to consumers. This paper investigates the impact of regulatory focus on brand attitudes after research participants viewed a luxury brand’s message on social media. The research question is whether promotion-focused consumers and prevention-focused consumers have different responses to messages that emphasize either innovation or tradition. Based on an online experiment, this research findings show that the framing of the message interacts with regulatory focus. An ad that emphasizes innovation yields more favorable brand attitudes than an ad that emphasizes tradition among promotion-focused consumers. However, this does not happen among prevention-focused consumers. This research provides theoretical implications and practical suggestions for industry practitioners.

Auto da Compadecida na televisão: a derrocada do macho nordestino
Authors: Lopes Pablo de Oliveira , Silva Lourdes Ana Pereira
Published: August 2023

Este trabalho pretende compreender a ruptura da figura do homem heterossexual por meio da análise da cena do duelo entre os personagens Chicó, Cabo Setenta e Vicentão, na microssérie O Auto da Compadecida (2000, TV Globo, direção de Guel Arraes). O artigo reflete sobre aspectos que dizem respeito às falas dos personagens e às suas atitudes, com base não só nos elementos lexicais, seus significados e sentidos proporcionados ao interlocutor, mas considerando também a forma como as estruturas sociais se fazem presentes no discurso, encarando que a sociedade e a linguagem estabelecem entre si uma relação simbiótica. Lançamos mão da Análise Crítica do Discurso (ACD), uma abordagem teórico-metodológica, que investiga de que maneira as formas linguísticas atuam na reprodução, manutenção e transformação social. Os analistas críticos do discurso concentram-se em analisar a reprodução do sexismo e do racismo, da legitimação do poder e o papel da política e da mídia na produção discursiva da relação de dominação entre grupos. Abordamos os conceitos de heteronormatividade, heterossexualidade e gênero, tendo como substratos as discussões presentes nas obras “Nordestino: uma invenção do falo - uma história do gênero masculino (Nordeste – 1920-1940)”, de Durval Muniz de Albuquerque Júnior (2013), e Manifesto Contrassexual: práticas subversivas de identidade sexual”, escrito por Paul Preciado (2014). A partir disso, propusemos a problematização da masculinidade, compreendendo-a como uma construção social, e depreendemos que as narrativas audiovisuais são importantes na construção de sentidos e que há padrões e estereótipos sobre o comportamento masculino em produções televisivas.

Authors: Pires Jandresson Dias , Dos Santos Gérson Rodrigues , De Sousa Marival Pereira , Pires Simone Santos
Published: August 2023

This article models, through Geostatistics, a database with space-time characteristics seeking to examine climate variations in the state of Bahia located in the Northeast region of Brazil. This dataset consists of information from 86 stations recorded by the National Institute of Meteorology (INMET) from January 2010 to December 2022 for the state. The focus of the analysis was to study the time series data related to air temperature. Initially, a descriptive analysis of the data was carried out and graphics were generated to understand the general climatic characteristics of the region, monthly. Then, Geostatistics was used to explore the structure of climate variations using semivariogram analysis to assess the spatial dependence of climate data, using ordinary kriging as an interpolating method for three theoretical models of semivariograms. The combination of the aforementioned methodologies allows the characterization of climate variations in the state of Bahia, in such a way that the discoveries can also contribute to the predictability of the climate in the region, providing insights for natural resource planning, agricultural management, climate prediction and adaptation strategies. The analysis was performed using the R programming language, which is recognized worldwide and used in climate studies.

Polysorbates (PS) are added to biopharmaceutical formulations to stabilize proteins and monoclonal antibodies (mAbs) and to prevent aggregation, denaturation, and surface adsorption. Polysorbate analysis can be challenging because of their inherent complexity, polydispersity, and their presence in matrices containing high concentrations of proteins and other excipients such as sugars, amino acids, salts, and buffers. This instalment of “Biopharmaceutical Perspectives” provides an overview of different approaches for the qualitative and quantitative analysis of polysorbates, its impurities and degradants in raw material, intermediate dilutions, drug substance, and drug products. Various gas (GC) and liquid chromatography (LC) methods and accompanying detection techniques are briefly discussed and illustrated with results obtained at the authors’ laboratory.
