In engineering assessments, accurate and reliable data is the foundation for sound decision-making. Yet, uncertainty in data—whether due to limitations in measurement techniques, variable loading conditions, or incomplete records—is an ever-present challenge. This article explores common sources of data uncertainty, guidance from API-579 and API-580 on managing it, and how to leverage risk matrices and […]
The new edition of the ASME B31.3 Process Piping Code is scheduled to be issued December 27, 2024. As usual, there are many clarifications, updated references to codes and standards, updates to basic allowable stresses, and additional listed materials. These types of changes are not described here. Note that many figures and tables have been […]
Monolithic refractory linings are a necessity of operating a variety of furnaces, boilers, and reactors in the refinery. Despite their prevalence, the “off-the-shelf” product looks nothing like the final durable and insulating lining that may be familiar. These materials are sold in dry bags of powder, like concrete from the hardware store, and require the […]
In the first part of our blog series on the Life Management of Pressure Swing Absorbers (PSA), we discussed the importance of accurately measuring weld peaking and how it influences stress and fatigue life. As we delve into the second part of this series, our focus shifts to the quality of Non-Destructive Testing (NDT) inspections, […]
The safe operation, maintenance, and reliability of floating roofs on storage tanks requires special considerations in their design, construction, and inspection practices. Over the past 100+ years, thousands of tanks with External Floating Roofs (EFRs), fixed roofs with Internal Floating Roofs (IFRs), and EFRs covered with domes have been used to store crude oil, refined […]
