BakerRisk’s paper “Managing Cold Temperature and Brittle Fracture Hazards in Pressure Vessels” authored by Nick Cherolis, David Wood and Dan Benac was recognized as the Best Paper in Volume 16 of the Journal of Failure Analysis and Prevention. The paper addresses brittle fractures of pressure vessels that can be both catastrophic and costly. The paper provides guidance in avoiding such failures by identifying some of the causes for cold embrittlement hazards and brittle fracture in pressure vessels. The paper also discusses how to assess existing equipment subject to cold conditions and brittle fracture concerns using BakerRisk’s Cold embrittlement tool which follows the guidelines of API 579-1/ASME FFS-1, Part 3.
The Best Paper Award was formally presented at the ASM Leadership Awards Luncheon at MS&T’17 held at the David L. Lawrence Convention Center in Pittsburgh, Pennsylvania, on Monday, October 9, 2017. The Best Paper was selected by the Editors and Editorial Review Board of the Journal and all papers published in Volume 16 were considered. BakerRisk performs Cold Embrittlement Reviews for pressure vessels. The cold embrittlement review is a multi-disciplined, low temperature brittle fracture assessment of piping and pressure vessels. The review assesses the materials used and the operating conditions to reduce the risk of a brittle fracture at facilities. This assessment evaluates the safeguards in place to control pressures and temperatures to avoid low temperature conditions and assesses the material behavior of the equipment. The assessment identifies potential scenarios for low temperature excursions and then reviews the process and equipment condition input from the plant to determine the critical exposure temperature (CET). The CET is being compared to the equipment minimum allowable temperature (MAT) which is determined using BakerRisk’s Cold embrittlement tool.
