January/February 2005 Inspectioneering JournalBy John Reynolds at Intertek
Amine cracking is a form of stress corrosion cracking, which is related to alkaline and carbonate stress corrosion cracking. Amine cracking is often intertwined with wet H2S and carbonate cracking, as amines, carbonates and wet sulfides often exist...

Corrosion fatigue is closely related to mechanical and vibration fatigue cracking, except that it is initiated and accelerated by a corrosion mechanism, especially one that gives rise to pitting, from which cracks often initiate. But that...

HTHA falls into multiple categories of corrosion mechanisms, including environmentally assisted cracking, hydrogen assisted cracking, and high temperature degradation. Sometimes HTHA is confused with low temperature hydrogen cracking mechanisms...

Hydrogen stress cracking occurs when corrosion from acids like wet hydrogen sulfide or hydrofluoric acid (HF) cause atomic hydrogen to penetrate hardened or higher strength steels and cause stress cracking.

Polythionic Acid Stress Corrosion Cracking (PASCC) is an affliction of many refineries processing sulfur containing feedstocks, and since that is the norm these days, most refiners reduce their susceptibility to PASCC by selecting resistant alloys...

The number of FFS assessments carried out by inspection engineers is expected to increase in the future, as operators "sweat" their ageing process equipment. The parameters required for assessments can be quite complex and interdependent. Therefore,...

Nearly ten years ago the magnetostrictive sensor (MsS) technology was reported in this journal (July/August 1996 Issue, Volume 2 Issue 4) as a method to detect corrosion in insulated piping. At that time, the MsS Technology consisted primarily of...

January/February 2005 Inspectioneering JournalBy Bob Stakenborghs, P.E. at Evisive Inc.
Several years ago, a need was identified to develop an improved nondestructive inspection method to volumetrically inspect dielectric materials. Specifically, an inspection method for detecting defects in rubber expansion joints was needed to assist...
