Repeat Piping Ruptures

Before

New Design

FEM analysis made to optimize cooler structure reinforcement

LocationRagusa – Sicily, Italy
ServiceLDPE Cooling
Machinery TypeEsslingen, 2nd Phase Reciprocating Compressor - High Pressure Cooler
Disch. Pressure3200 bar

Challenge

Customer faced severe reliability issues, repeated piping ruptures due to high vibrations (up to 250 mm/s) Solution to be implemented within 1 week shut down

Solution

  • We completed an FEM study of the mechanical system to define modifications to existing supports and structure
  • Foundations were reinforced through grouting
  • Site survey was conducted to confirm root cause analysis and resolution

Result

Solution implemented in the shut down time, vibrations reduced below SWRI danger value
