Overall, the condition of each spool was good, rust staining was apparent predominantly where the test water had drained out of the test spools, but no pitting corrosion could be found (Figure 5).
Two main corrosion mechanisms, namely, general corrosion and pitting corrosion are recognized.
The common corrosion types are mainly galvanic corrosion, pitting corrosion, filiform corrosion and stress corrosion of these.
Pitting potential was measured to address concerns about snow melting agents containing chlorine causing pitting corrosion on the outer surface of exhaust system parts.
NNDT performed more effectively in H2SO4 than in HCl based on corrosion rate and inhibition efficiency values from weight loss, open circuit potential and potentiodynamic polarization tests because chloride ions (Cl-) ions are more aggressive than sulphate ions (SO4 ) on the steel, initiate general and pitting corrosion [22-26].
Sandvik says the high strength, austenitic nickel-chromium alloy Sanicro 60 (UNS N06625), exhibits very good resistance to pitting corrosion, intergranular corrosion and is virtually immune to stress corrosion cracking (SCC) in chloride containing environments.
The work uses state-of-the-art analytical techniques and focuses on the mechanisms behind pitting corrosion and how best to prevent it.
This is due to the combined effect of nonuniform pitting corrosion along the length of longitudinal reinforcement and corrosion of horizontal tie reinforcement.

Analysis of pipeline failure causes also shows that other often reasons causing pipe damage, especially, through-wall defect formation, are pitting corrosion [9, 21], damage caused by cyclic loading where corrosion-fatigue mechanism appears (usually in welding zone) [21, 24,28], and under particular conditions - hydrogen absorption (hydrogen brittleness) [29-31] and microbiological corrosion [9, 32, 33].
