Root cause analysis

Prevention by determinaton of the root cause

When an incident occurs, you need to understand why in order to ensure it never happens again. Sulzer can perform root cause failure analyses for gas and steam turbines, centrifugal, axial, and screw compressors, as well as hot gas expanders.

We help you analyze failures

Using state-of-the-art techniques and technologies, our experienced personnel can help you determine the factors that led to the incident.

Metallurgical evaluations

  • In-house metallurgical laboratory
  • Scanning Electron Microscopy (SEM) with Energy Dispersive Analysis X-Ray (EDAX) analysis
  • In-house Non-Destructive Testing (NDT) and destructive testing
  • In-situ metallography
  • Stress rupture/tensile testing

Rotordynamic analysis

  • Lateral and torsional
  • Bearing and seal re-design

Finite-element structural analysis

  • Static and modal analyses of impellers, turbine blades, and other components
  • Simluations of hydrostatic tests and high-temperature heat-treatments of critical components

Field vibration data

  • Frequency response data from impact testing
  • Vibration and alignment data from field operation

We support you and try to offer the best solution at the lowest cost and in the most efficient manner possible. Prevention of recurring incidents is of utmost importance for us—and for you.
