Brittle Fracture is Rare – But Typically Catastrophic
E2G | The Equity Engineering Group provides a comprehensive screening program for pressure vessels, piping, and storage tanks. The program is consistent with the API 579-1/ASME FFS-1 Fitness-for-Service methodologies to assess the susceptibility to catastrophic brittle fracture failures.
This program will help you meet OSHA 1910.119 PSM RAGAGEP requirements.
Are You a Candidate for Brittle Fracture Screening?
- Was the equipment built prior to the 1987 addendum of ASME Section VIII Division 1?*
- Was susceptibility to brittle fracture not considered in the original design?
- Has there been a change in process operating conditions that increases the possibility of low metal temperatures?
- Has a PHA indicated that process or ambient temperatures lower than anticipated in the original design are possible (including depressurization and/or auto-refrigeration potential)?
- Has the equipment item been rerated using a lower design margin?
- Looking to optimize startups or shutdowns?
- Looking to perform a hydrostatic pressure test?
*Prior to 1987, most pressure vessels did not require a formal evaluation to address brittle fracture.
We Employ Industry-Wide Standards (Many of which were developed by Equity Engineering Group)
E2G follows Part 3 API 579-1/ASME FFS-1 Fitness-for-Service standards to screen for brittle fracture propensity. As the principal investigator for these standards, E2G is well-positioned to interpret them for your facility’s equipment evaluation. This includes the following:
- Screening of equipment for susceptibility (Level 1 and 2)
- Detailed assessment using fracture mechanics (Level 3)
Why Complete a Brittle Fracture Project?
- Numerous catastrophic brittle fracture failures have occurred in the industry
- All design and post-construction codes have taken action to address the industry concern
- OSHA 1910.119 PSM RAGAGEP requirements
