The inlet pressure drop rule is designed to protect pressure relief valves (PRVs) from instability; however, recent changes to API 520 allow the pressure drop to go above 3% of the set pressure if a supplementary engineering analysis is completed. This article, published in the September 2021 issue of World Fertilizer, discusses the improvements to the API codes and standards and how those changes impact the 3% rule.

Pipeline regulations in Canada differ from the ASME B31.4 and B31.8 standards used across the United States. In this article, the authors provide a detailed overview of the federally regulated CSA Z662 standard and clarify the differences between assessments (Section 10), engineering assessments (Section 3.4), and engineering critical assessments (Annex J & K). This is a must- read for any pipeline operators who wants to understand Canadian pipeline industry regulation and engineering assessment requirements.
A recurring challenge is ensuring that modeling assumptions in pipe stress analysis don’t create hidden risks for rotating equipment and piping code compliance. This article explores how friction and vertical support behavior can dramatically influence nozzle load calculations, sometimes turning a compliant system into a non-compliant one. Using case studies and practical examples, the authors highlight best practices and advanced tools like SIMFLEX-IV to improve accuracy and reliability across complex operating conditions.
Typically, maintenance teams are focused on a facility’s pressure vessels, piping, and tanks, which leaves structural infrastructure to be overlooked. In this article, Derek shares several case studies that highlight how combining structural and mechanical engineering approaches can solve several unique fixed equipment challenges.
Up until the recent publication of ASME SBS-2023: Structures for Bulk Solids (ASME SBS), there has not been a comprehensive American standard for the design and construction of metallic structures
