LDPE High Pressure Cooler
Problem

Ruptures on cooler and HP piping (every 2-3 months)

  • high vibrations (up to 250 mm/s rms)
  • modifications to be performed in one week
Solution
  • FEM study of the mechanical system to define modifications to existing supports and structure
  • foundations reinforced through grouting
  • follow-up survey to confirm root cause analysis and resolution
