Book Synopsis Study on Effects of Soil Properties Towards Corrosion of Carbon Steel Pipeline by : Wan Muhammad Azamuddin Wan Azmi
Download or read book Study on Effects of Soil Properties Towards Corrosion of Carbon Steel Pipeline written by Wan Muhammad Azamuddin Wan Azmi and published by . This book was released on 2014 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion is one of the most terrifying incidents that engineers does not want on the pipeline, especially when involving billion of dollars losses. Many industries depended on the pipeline for transporting their raw material or products from the places of source to the place of treatment and finally to the consumers. Among the industries that widely used the function of pipeline were oil and gas industries, water treatment and also crude oil industries. Therefore, as the most important part in transportation role, pipeline need to be ensured always in great condition and anything that could cause damages to these railways must be control immediately before unwanted accident happens. Currently, there were report that said pipeline damages was very dangerous to the environment whether to the human being or to the nature. There were some human fatality and body damages of the environment that caused billion of dollars losses. Due to all consequences that would occur in the future as the punishment for the lack of information on the conservation of pipelines, the research based on this problem will be done to find out the cause of buried pipelines damages due to the soil. The research will focus on the soil properties and its effects towards the corrosion of carbon steel pipeline. The parameters that will be the variables in this research are clay content, moisture content, pH value and also particles size of soil. Relationship between these parameters with the corrosion rate will be investigated properly. The pipelines samples will be taken from actual segment and will be buried in different condition of soil based on previous parameters. About 180 samples plates will be buried for at least 5 months to get the real corrosion rate for different type of soil condition. Once a month the retrieval procedure will be done to check the rate of corrosion and also to ensure the soil properties remain stables as been set up. After all the samples had been retrieve from its medium of different soil conditions, the data will be interpreted in form of tables and graph to shows different parameters will get different results. The result from linear regression analysis and also using excel analysis had shown that the pH parameter were could accept the hypothesis of pH condition were the major influence in corrosion rate phenomenon while others had rejected the hypothesis to become the major influence. The ANOVA analysis also shown the correlation coefficient of all the parameters were high but only the pH condition were satisfy the significance value with lower than 0.05. The pH condition, moisture and clay parameter could be study further while the particles size particles does not suitable for further study.

Book Synopsis Field Soil Corrosivity Testing--Engineering Considerations by : JD. Palmer
Download or read book Field Soil Corrosivity Testing--Engineering Considerations written by JD. Palmer and published by . This book was released on 1990 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state of the art in soil corrosivity testing was evaluated, with particular emphasis on field and in-situ tests that can be performed with reasonable accuracy by nonscientific personnel. Parameters reviewed include resistivity, pH, redox potential, moisture content, chloride levels, structure/soil potential, and microbiological activity. The reliability of in-situ tests versus laboratory tests is examined. Particular emphasis is placed on buried and immersed ferrous materials. A distinction is made between studies intended to determine the soil factors affecting the integrity of intended new installations and studies which examine the condition of the existing facilities and the relationship of soil parameters to structure condition and anticipated life. The latter circumstance is becoming increasingly evident as infrastructure rehabilitation studies focus on the condition and future life expectancy of buried facilities. Several approaches to expected life prediction are reviewed. Emphasis is focused on information presented in ASTM STP 741, Underground Corrosion, and ASTM STP1013, Effects of Soil Characteristics on Corrosion. The applicability of the ASTM Method for Field Measurement of Soil Resistivity Using the Wenner Four-Electrode Method (G 57-78) and the ASTM Test Method for pH of Soil for Use in Corrosion Testing (G 51-84) is considered. The available information is consolidated into recommended practices for soil corrosivity evaluations.

Book Synopsis Environmental Soil Properties and Behaviour by : Raymond N. Yong
Download or read book Environmental Soil Properties and Behaviour written by Raymond N. Yong and published by CRC Press. This book was released on 2012-03-05 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: From bridges and tunnels to nuclear waste repositories, structures require that soils maintain their design engineering properties if the structures are to reach their projected life spans. The same is true for earth dams, levees, buffers, barriers for landfills, and other structures that use soils as engineered materials. Yet soil, a natural resource, continues to change as a result of natural and anthropogenic stresses. As the discipline of soil properties and behaviours matures, new tools and techniques are making it possible to study these properties and behaviours in more depth. What Happens to Soil Under Weathering, Aging, and Chemical Stress? Environmental Soil Properties and Behaviour examines changes in soil properties and behaviour caused by short- and long-term stresses from anthropogenic activities and environmental forces. Introducing new concepts of soil behaviour, soil maturation, and soil functionality, it integrates soil physics, soil chemistry, and soil mechanics as vital factors in soil engineering. The book focuses on environmental soil behaviour, with particular attention to two main inter-related groups of soil–environment issues. The first is the use of soil as an environmental tool for management and containment of toxic and hazardous waste materials. The second is the impact of ageing and weathering processes and soil contamination on the properties and behaviour of soils, especially those used in geotechnical and geoenvironmental engineering projects. A Transdisciplinary Look at Soil-Changing Processes To determine short- and long-term soil quality and soil functionality, the authors emphasize the need to be aware of the nature of the stressors involved as well as the kinds of soil-changing processes that are evoked. This book takes a first step toward a much-needed transdisciplinary effort to develop a broader and deeper understanding of what happens to soil and how we can determine and quantify the effect of biogeochemical processes. It offers a timely resource for the study of soil properties and behaviours, effects of environmental changes, and remediation of contaminated soil.
Book Synopsis Atmospheric Corrosion by : Christofer Leygraf
Download or read book Atmospheric Corrosion written by Christofer Leygraf and published by John Wiley & Sons. This book was released on 2016-06-07 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: ATMOSPHERIC CORROSION Presents a comprehensive look at atmospheric corrosion, combining expertise in corrosion science and atmospheric chemistry Atmospheric corrosion has been a subject of engineering study, largely empirical, for nearly a century. Scientists came to the field rather later on and had considerable difficulty bringing their arsenal of tools to bear on the problem. Atmospheric corrosion was traditionally studied by specialists in corrosion having little knowledge of atmospheric chemistry, history, or prospects. Atmospheric Corrosion provides a combined approach bringing together experimental corrosion and atmospheric chemistry. The second edition expands on this approach by including environmental aspects of corrosion, atmospheric corrosion modeling, and international corrosion exposure programs. The combination of specialties provides a more comprehensive coverage of the topic. These scientific insights into the corrosion process and its amelioration are the focus of this book. Key topics include the following: Basic principles of atmospheric corrosion chemistry Corrosion mechanisms in controlled and uncontrolled environments Degradation of materials in architectural, transport, and structural applications; electronic devices; and cultural artifacts Protection of existing materials and choosing new ones that resist corrosion Prediction of how and where atmospheric corrosion may evolve in the future Complete with appendices discussing experimental techniques, computer models, and the degradation of specific metals, Atmospheric Corrosion, Second Edition continues to be an invaluable resource for corrosion scientists, corrosion engineers, conservators, environmental scientists, and anyone interested in the theory and application of this evolving field. The book concerns primarily the atmospheric corrosion of metals and is written at a level suitable for advanced undergraduates or beginning graduate students in any of the physical or engineering sciences.
Book Synopsis The Effect of Soil Resistivity and Soil Temperature on the Corrosion of Galvanically Coupled Metals in Soil by : E. Escalante
Download or read book The Effect of Soil Resistivity and Soil Temperature on the Corrosion of Galvanically Coupled Metals in Soil written by E. Escalante and published by . This book was released on 1988 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galvanic corrosion current measurements carried out on stressed Type 301 stainless steel coupled to zinc at six underground test sites over a period of four years indicate that the galvanic current is controlled by soil resistivity or oxygen availability in the soil. In well aerated soils, resistivity plays a dominant role, but in poorly aerated soils, oxygen controls the corrosion process. Furthermore, at a certain depth, approximately 1 m, soil resistivity is strongly influenced by soil temperature and only slightly affected by soil moisture. Finally, Type 301 stainless steel in a half-hard or full-hard condition is susceptible to hydrogen embrittlement failure in soil when exposed to potentials capable of causing hydrogen evolution.
Book Synopsis Geophysical Methods for Assessments of Soil Corrosivity by : Ravin Navneet Deo
Download or read book Geophysical Methods for Assessments of Soil Corrosivity written by Ravin Navneet Deo and published by . This book was released on 2012 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil corrosion is a complex and multi-disciplinary problem affecting a range of engineering assets and critical civil infrastructure. Although significant efforts are being made to improve the life-time of metallic assets in the soil environment, failures continue to occur due to deterioration brought about by external corrosion. Pipelines are one such category of buried assets. As part of urban management strategies, emphasis is placed on maintaining and extending the life of these assets. Consequently, knowledge on the corrosivity of the environment in which these pipelines are embedded is considered essential. For this purpose a range of assessment methods are available, which can be conducted on either laboratory soil samples, or in-situ conditions. However, with increase in costs associated with premature failures as well as maintenance, there is an interest to deepen the scientific understanding of the pipeline corrosion phenomenon and improve existing life-time prediction models. In this regard, the present thesis has attempted to contribute to different aspects of the soil corrosion discipline, through a mixture of intensive laboratory as well as geophysical field study. For the first time a galvanostatic pulse technique has been successfully applied to evaluate the electrical double layer properties at the metal/soil interface as well as to determine other corrosion related parameters. This has been conducted for synthetic soil samples in order to allow control over a multitude of variables. The choice of this technique is based on its ability to isolate bulk resistances from corrosion related process, as well as its ability to identify possible effects from soil capacitances. An important outcome of this study is that an experimental procedure is given, which allows consistent treatment of soils of various grain size distributions. Secondly, another detailed laboratory study has been conducted in order to illustrate the importance of integrating spectral induced polarization methods as part of normal assessment methods for identification of potentially corrosive soils. Synthetic soil samples from the aforementioned corrosion study were analyzed for their spectral responses in the frequency range 0.1 - 1000 Hz. Further information was extracted by fitting the acquired data using the Cole-Cole model. Overall it is shown that, apart from soil resistivities, the normalized chargeability parameter correlates with the polarization resistance, an important corrosion related parameter, when the soil physical properties manifest in the corrosion process. New ways of identifying potentially corrosive soils are also presented. This effectively extends the use of electrical characterizations for assessing soil corrosivity. Following these detailed laboratory studies, a field study is reported. Here, for the first time, the combined direct current resistivity and time-domain induced polarization (DC-TDIP) profiling methods are used to assess site conditions along a pipeline right-of-way. Additional insights on the field results are provided by laboratory analysis of soil samples acquired systematically along the pipeline right-of-way from depths near to the buried pipeline. Following this, a methodological framework is suggested to assist in developing further capacities for the use of DC-TDIP methods for in-situ soil corrosivity assessments. In particular a distribution of self potential gradients is observed along the pipeline right-of-way suggesting zones of active electrolysis and enhanced external corrosivity.

Book Synopsis Review of the Bureau of Reclamation's Corrosion Prevention Standards for Ductile Iron Pipe by : National Research Council
Download or read book Review of the Bureau of Reclamation's Corrosion Prevention Standards for Ductile Iron Pipe written by National Research Council and published by National Academies Press. This book was released on 2009-11-19 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ductile iron pipe (DIP) was introduced about 50 years ago as a more economical and better-performing product for water transmission and distribution. As with iron or steel pipes, DIP is subject to corrosion, the rate of which depends on the environment in which the pipe is placed. Corrosion mitigation protocols are employed to slow the corrosion process to an acceptable rate for the application. When to use corrosion mitigation systems, and which system, depends on the corrosivity of the soils in which the pipeline is buried. The Bureau of Reclamation's specification for DIP in highly corrosive soil has been contested by some as an overly stringent requirement, necessitating the pipe to be modified from its as-manufactured state and thereby adding unnecessary cost to a pipeline system. This book evaluates the specifications in question and presents findings and recommendations. Specifically, the authoring committee answers the following questions: Does polyethylene encasement with cathodic protection work on ductile iron pipe installed in highly corrosive soils? Will polyethylene encasement and cathodic protection reliably provide a minimum service life of 50 years? What possible alternative corrosion mitigation methods for DIP would provide a service life of 50 years?
