Challenge

Δp on a temporary strainer quickly rose to ~1.3 bar

  • Customer could not stop production before scheduled maintenance

Solution

  • Finite element analysis and a buckling analysis
  • Maximum sustainable pressure drop ~ 4 bar

Result

Maintenance executed after one year, as originally planned
