Failure Analysis Services
Kalsi Engineering provides complete analysis, testing, technical reporting, and expert witness testimony services to investigate failures in mechanical equipment and structures. Our clients include equipment manufacturers, equipment users, plants, law firms, and insurance companies. Our extensive experience in root cause analysis and testing, augmented by our in-depth understanding of the design and performance aspects of mechanical equipment, enables us to provide a complete failure analysis service to our clients.
The KEI staff takes a disciplined approach in identifying whether a failure is caused by design deficiencies, material defects, operational overloads, abuse, misapplication, inadequate maintenance, or use beyond design life.
We conduct tests in our Houston-area laboratory in which we deliberately take equipment to failure in order to confirm the root cause. In some cases, the objective of a failure analysis is to identify the limiting component so that design modifications can be developed to improve performance and reliability of the equipment.
Kalsi Engineering provides the following failure analysis services:
- Failure Modes and Effects Analysis (FMEA)
- Root-Cause Analysis
- Inspection of Failed Parts
- Confirmation Testing
- Failure Analysis due to Fatigue and Overload
Kalsi Engineering has performed a wide variety of failure analyses. A list of key projects is provided.
- Stem separation in 24-inch globe valve due to misalignment of the plug and seat
- Stem separation in gate valve due to misalignment of backstop and gate
- Stem separation in main steam isolation valve due to improper tail-link loading
- Stem separation failure in a double-ported globe valve
- Globe-valve internals damaged due to high side-load forces
- Check valve wear and failure analysis
- Investigation into the failure of drill pipe tool joints in an offshore drilling application
- Failure of several 48-inch pipeline flanges and valves at a crude oil tanker loading terminal due to hydraulic transients
- Failure of a combination friction clutch and brake mechanism in a high-speed automatic punch
- Investigation of a steam turbine that failed by over-speeding
- Failure of a tilting disc check valve to close upon sudden flow reversal causing a reactor scram at a nuclear power plant
- Determination of cause of repetitive failures of a feedwater pump impeller shaft
- Investigation of multiple swing check valve failures during reduced capacity operation
- Cyclic testing to determine fatigue life of electric motor-powered actuators by taking them to failure
