On the basis of a deeper understanding of this threat today, integrity management programs have been developed further in the recent past The detection of SCC with conventional liquid coupled ultrasonic technology is well accepted within the pipeline industry. Part of this acceptance is the successful application of such assessment standards as API 579. It has been shown that the conventional ultrasonic technology is sensitive and accurate enough to meet the needs of the standard. Recently, another form of ultrasonic technology has been recognized as a competitive alternative for in-line inspection tools. The electromagnetic acoustic transducer (EMAT) based ultrasonic technology does not require a liquid coupling making it cost effective for use in gas pipelines. In recent years, a newer generation of Electro-Magnetic Acoustic Technology tools has been made available and a process is on the way to establish this technology as a future option for gas pipeline operators [1,2]. In this paper results from the inspection of several gas pipelines and a series of pull-tests are used to show that EMAT technology is sufficiently sensitive and accurate to meet industry standards like API 579, making it a viable option for pipeline operators, especially for transportation of gaseous media برای مشاهده این محتوا لطفاً ثبت نام کنید یا وارد شوید. ورود یا ثبت نام ٰTitle:PIPELINE CORROSION AND INTEGRITY MANAGEMENT - EXPERIENCE FROM THE FORTIES FIELD Author:J. Marsh,P. C. Duncan, M. Richardson keyword: not available Abstract In 2003, the present operator aquired the Forties Field. The field has been in operation for 33 years and has exceeded its original design life of 20-25 years. The present owner intends to continue production in the Forties Field for, potentially, in excess of another 15 years. They have identified a number of issues with respect to the corrosion and integrity management of the infield pipeline system. In a previous publication the corrosion issues influencing the infield pipeline system have been examined, and the steps taken to ensure effective corrosion management have been discussed. This present publication examines in detail some specific recent integrity issues arising from the intelligent pigging program, from which important lessons have been learned. These integrity issues include microbial influenced corrosion and modeling, an intelligent pig run that failed to identify a defect that subsequently lead to a leak, and the importance of a rapid response capability when such integrity issues occur برای مشاهده این محتوا لطفاً ثبت نام کنید یا وارد شوید. ورود یا ثبت نام Title:DEVELOPMENT OF GUIDELINES FOR THE IDENTIFICATION OF SCC SITES AND THE PREDICTION OF RE-INSPECTION INTERVALS FOR SCC DA Authors:Fraser King ,Mark Piazza keyword: not available Abstract A significant amount of research and development (R&D) has been carried out on the mechanism of the stress corrosion cracking (SCC) of underground pipelines since the phenomenon was first recognized in the 1960’s. This R&D has taken the form of both laboratory-based experimental investigations and the direct measurements and observations of SCC on operating pipeline systems. Correlation of these data sets may be useful for predicting the occurrence and severity of SCC in the field. An effort is underway, co-funded by Pipeline Research Council International (PRCI), the US DOT, and pipeline companies, to consolidate the results of these various studies in the form of a set of guidelines that will assist companies in locating SCC on their systems, establishing the frequency of inspection intervals, and predicting the need for and timing for mitigation برای مشاهده این محتوا لطفاً ثبت نام کنید یا وارد شوید. ورود یا ثبت نام 2 نقل قول لینک به دیدگاه

Simek Keyword: not availble ABSTRACT Magnetic flux leakage is one of the most common and robust methods of ILI (In Line Inspection) used by pipeline operators worldwide to detect and characterize a broad range of pipeline features and anomalies. Magnetic flux leakage data signals are influenced by the shape and configuration of metal loss zones; with the feature shapes used as a basis for algorithm development and interpretation techniques developed to provide estimates of metal loss lengths, widths and depths. For pipelines, primary lengths and widths of features may be oriented in any random direction with respect to the pipeline axis and applied magnetic fields. In addition to field levels, material properties, velocity effects, length, width, and depth, feature orientation will also influence the magnetic field data acquired for typical pipeline metal loss anomalies. Difficulties encountered in characterizing specific classes of metal loss features have led to the development, implementation, and use of tools employing multiple axis sensors in an effort to improve performance for these categories of metal loss features. To demonstrate the effects of feature orientation, examples will be presented with the results providing insights into the signal response for metal loss zones as the angular orientation of the features are varied within the applied magnetic field. برای مشاهده این محتوا لطفاً ثبت نام کنید یا وارد شوید. ورود یا ثبت نام نقل قول لینک به دیدگاه
