Description
This webinar explains why transient modeling is essential for evaluating tube rupture scenarios in heat exchangers during CAPEX and brownfield projects. The presenters walk through industry guidance from API and the Energy Institute, demonstrate how pressure pulses form during high pressure gas releases, and compare one dimensional modeling options. Real examples illustrate how transient effects influence relief sizing, equipment protection, and mitigation decisions when conventional steady state methods underestimate risk.
Key Topics Covered
- API 521 requirements for evaluating tube rupture scenarios
- Energy Institute guidance on high pressure to low pressure failures
- Comparison of one dimensional transient modeling methods
- How pressure spikes propagate through exchanger shells and piping
- Differences between two orifice, single orifice, and one tube flow assumptions
- Mitigation options such as relief upgrades, rupture disks, piping class revisions, and design considerations
What You’ll Learn
- Why steady state modeling can underpredict pressure during tube rupture events
- When transient analysis is required based on pressure differential and process conditions
- How to select and apply transient models, including the Samaria method
- How rupture location, opening time, friction, and exchanger geometry influence peak pressures
- How to evaluate whether equipment exceeds MAWP, hydrotest pressure, or natural frequency thresholds
Who This Webinar Is For
Project engineers, process engineers, mechanical integrity specialists, PSM professionals, and design teams involved in CAPEX projects, exchanger design verification, relief system evaluation, and equipment protection in refining, petrochemical, chemical, and offshore facilities.
