Corrosion and Failure Analysis Case History Index

Note!

The following corrosion and failure analysis case histories are a subset of the more than nine hundred corrosion and failure analysis projects we have conducted over the years. They were selected to represent the many corrosion and failure mechanisms that we have encountered while consulting in the chemical, refining, oil & gas and pulp & paper industries. More will be added from our archives and ongoing project activities as time allows.

Case History 001 - Hydrogen embrittlement failure of valve body capscrews.

Case History 002 - Underdeposit corrosion of a galvanized water heater nipple.

Case History 003 - Corrosion fatigue of a carbon steel rotor in a downhole motor.

Case History 004 - Non-metallic inclusions in a Gr. 8 hex head bolt.

Case History 005 - Rotating fatigue failure of a hex head bolt.

Case History 006 - Chloride stress corrosion cracking of 316 stainless steel.

Case History 007 - Polythionic Acid (PTASCC) cracking failure

Case History 008 - Fatigue and hydrogen embrittlement failure of a downhole motor drive shaft coupling.
