When it comes to corrosion engineering, seawater is one of the most important environments to discuss. Here we'll take a look at what causes pipeline corrosion
By: Mehdi Yari | Electrochemistry and Corrosion Laboratory at the University of Western Ontario
Chloride stress corrosion cracking (Cl-SCC) is the most common type of cracking of austenitic stainless steel. It has been the observed cause of metal...
By: Steven Bradley | Principal Consultant, Bradley Consulting Services
Pitting corrosion can have serious implications because the cavity it bores below the surface can be both wide and deep, thus seriously affecting the load...

A discussion of salt contamination on coating performance, risk assessment techniques and test methods before coating application and some methods for salt contamination removal.
By: Mohamed Adel Mohamadein | Head of the Corrosion, Arab Petroleum Pipelines
The presence of non-visible residual surface salts and their impact on life cycle coating performance is well documented, yet no widespread industry standards exist to easily reference levels that will diminish the risk of...
