...Abstract The corrosion failure of the Light Vacuum Condensate (LVC) draw piping line in a vacuum tower was investigated to identify the damage mechanism. The failure was localized at the LVC draw elbow near the tower's draw nozzle, with significant corrosion observed in the outlet straight piping...

...Abstract Regenerative amine systems are a crucial part of gas processing plants, responsible for removing impurities and contaminants from natural gas. However, their operation also poses significant corrosion risks to carbon and stainless steel materials, leading to potential equipment failure...

... was investigated by introducing 0.05 wt.% fine graphene particles GNP into a commercial epoxy glass flake (GF) paint. Electrochemical impedance spectroscopy (EIS), corrosion creepage after long-term saltwater and UV exposure were used to assess corrosion resistance performance. The coating’s mechanical performance...

... and SS. Model geometry In highly corrosive environments, the higher material cost of SS reinforcement may be balanced by its greater tolerance to chlorides, resulting in a longer time to corrosion initiation [ 15 , 16 , 17 , 18 , 19 ]. In addition to higher chloride tolerance, there is evidence...

... conclude the direct root cause, contributing factors, mitigation, preventive measure and other control techniques. This paper will provide significant information to the industry to avoid similar failure in near future either existing or new constructional facility. Corrosion Damage Mechanism Acidic...

... if there are any corrosion conditions present that could result in the loss of the integrity of the container package. Through-wall penetration of the inner container is considered a potential problem since it could allow the leakage of corrosive gases into the outer container of the 3013-container package. Any...

...Abstract Zinc metallizing with a high purity zinc wire plus a topcoat has been utilized in Europe for external corrosion control of iron pipe for over 65 years and in the United States for over 35 years. This method of external corrosion protection for ductile iron pipe has been under evaluation...

...Most of the literary works indicate that the use of OFSs for corrosion monitoring has been carried out in ambient air, under high pressure conditions, or in concrete structures. However, there is little or no work that describes corrosion monitoring in aquatic environments or in soil. Monitoring...

...Abstract The “18-8” type stainless steels perform well with lower corrosion rates in caustic at all concentrations up to approximately 65°C. However, literature shows that it is likely that the corrosion performance of such stainless steel, especially the welds are influenced by the contaminants...

... corrosion of transportation assets. The formation of such acidic phases is believed to be triggered by reaching a certain impurity limit. This can occur under difficult-to-predict conditions, which commonly used thermodynamic frameworks cannot predict. The solubility of impurities in CO₂-rich...

...Abstract Bridge decks exposed to de-icing agents and marine environments often deteriorate due to chloride-induced corrosion. Investigations characterizing current condition and expected future durability are critical to facilitating appropriate selection and timing of rehabilitation actions...

... cable length significantly. [ 3 ] Figure 2 shows a statistical analysis of the main reasons SLB’s hepta-cables were cut during operations and maintenance between 2022-2023. Armor corrosion is the leading cause of cable cuts, dramatically reducing cable length and lifetime. Also, it was noticed...

... any chlorides in the feed to hydrochloric acid (HCl) and ammonium chlorides (NH3CL). Hydrocracking units contain various corrodent compounds which will produce serious corrosion impact on different metallurgy in various temperature zones. Corrosion in hydrocracking units can be minimized with various...
