FRALEX CS-001 — Steam Explosion During a Re-Injection | White Paper Summary

FRALEX CS-001 White Paper — 2013 Refinery Steam Explosion | Failure Chain Analysis | FRALEX ESS

Free white paper. A 16" gate valve. 70 bar boiler water. Two fatalities.

The disaster did not begin on the day of the explosion. It began during valve manufacturing — and passed through five missed stop points over four years before two technicians were killed.

This white paper summarizes FRALEX Case Study CS-001 — a multi-year failure chain analysis of the 2013 refinery steam explosion triggered during a routine re-injection into an existing leak-sealing clamp.

This white paper covers: Full 7-stage failure chain from RTJ groove deviation to bonnet separation | Mechanical load analysis: 903 kN axial force on 6 intact bolts out of 20 | Stress Corrosion Cracking mechanism — all four conditions present | Five missed stop points and corrective action available at each | Five FRALEX engineering principles for integrity-based intervention decisions | FRALEX 4-step decision logic for re-injection work

The full CS-001 document (82 pages) including load calculations, SCC chain analysis, Integrity Evaluation Matrix, and Stop-Point Table is available in the FRALEX Veritas Library.

For: HSE Managers | Asset Integrity Engineers | Maintenance Leads | Anyone responsible for live intervention decisions on pressurized systems
