If you are looking for an expert witness you already have a costly problem! In the past, disputes were settled with firearms or fists, or perhaps a handshake. Now they are settled with attorneys. If you’re in this situation, you probably know you need a highly competent law firm and attorney to handle your case. […]
Update The new edition for ASME B31.3, Process Piping, has been issued (December 2020). As usual, there are many clarifications, updated references to codes and standards, updates to basic allowable stresses and added listed materials to the 2018 Edition. Becht has members on the involved ASME B31 committees and we are committed to sharing […]
The American Society of Mechanical Engineers (ASME) Honors & Awards program celebrates individuals who have made important contributions in various engineering disciplines. Awards recognize those who have made major achievements, presented groundbreaking papers or demonstrated a commitment of service to the Society. Don Frikken was recently awarded the J. Hall Taylor Medal for his distinguished […]
Originally posted to Asian Downstream Insights The future of the downstream industry: a vast, uncertain horizon, marked by new technologies, and the drive for new business models. At a recent executive virtual round-table, chaired by José de Sá, Senior Partner in Bain & Company’s Rio de Janeiro office and Global Head of O&G Downstream, business leaders […]
The COVID-19 pandemic has sparked a renewed focus on planning for sustainability and achieving the goals of the Paris Climate Agreement (PCA). These fundamental shifts are strongly evident in the European Union. EU capitals have been put under pressure to agree to reducing greenhouse gas emissions by 60% by 2030 compared with 1990, after the […]
Overview The first four parts of this series have described the updated Becht HTHA model and presented extensive validation for its application to Carbon Steel and C-0.5Mo. Based on this validation, time-based Nelson Curves for Carbon Steel (CS) and C-0.5Mo suitable for inclusion in API RP 941 [1] are now presented. General Assumptions Curves are […]
Overview Part 3 of this series presented the data set and calibration used to characterize C-0.5Mo performance. This part extends the calibration to Carbon Steel using the same basic calibration procedure. Unlike C-0.5Mo where carbon activity was used as the calibration parameter, for Carbon Steel the carbon activity is assumed to be 1 in all […]
Overview Part 2 of this series presented the extension of our model to C-0.5Mo material and calibration to very detailed through-wall damage data for five C-0.5Mo cases (from [1]). This part completes the analysis of C-0.5Mo by including data from API RP 941 [2] (including both plotted and file points) and the remaining cases from […]
Overview In Part 1 of this blog series an overview of two basic extensions to our void growth based HTHA model was given. In this part, validation of through-wall damage predictions are provided by leveraging the unique and exceptionally detailed work presented in the Peng Lui PhD dissertation [1]. Validation is critical for any model, […]
Overview This past spring, we described how we’ve incorporated well-established void growth modeling into our high temperature hydrogen attack (HTHA) assessment approach [1]. The purpose of this extension was to blend a reliable time basis for HTHA with our existing critical factor-based method (also published in the Inspectioneering Journal 6 years earlier [2]). The Inspectioneering […]
