...The paint top-coat provides extra barrier protection for the zinc, but the main reason for the synergy of duplex coatings is that the metallic zinc coating supports the paint when it begins to fail and prevents corrosion creep and other mechanisms of paint failure from proceeding anywhere near...

... technology of Oil & Gas production. Corrosion, fatigue and corrosion-fatigue are common failure modes that limit life of the sucker rods that drive these pumps. Of these, corrosion fatigue is probably the most common. The initiation site for corrosion fatigue is typically a corrosion pit. The factors...

...ABSTRACT Hydrothermal liquefaction (HTL) is a promising thermochemical pathway developed to convert wet biomass or waste biomass into valuable bio-oil and biochemical products in hot pressurized water medium. Over the past few years, some studies have initiated to investigate the corrosion...

... important parameters can still be addressed when materials are screened. Important corrosion rate promoters as low pH and temperature ≥ 300 °C has been tested in the equipment described here. ABSTRACT Harsh geothermal fluid demands corrosion resistant alloys (CRA’s) instead of the traditional carbon steel...

...Abstract Material selection for Monoethylene glycol (MEG) regeneration units is a challenge due to the high temperature combined with high salt content. The oxygen level is low, and carbon steel is a cost-effective choice. The corrosion rate of carbon steel is too high in neutral or acidic...

...Abstract Corrosion is a major concern in transmission pipelines that transport captured CO₂. While dry CO₂ is noncorrosive, significant corrosion has been reported in dense phase CO₂ with trace amounts of water and impurities such as O₂, H₂S...

...ABSTRACT Biomass derived pyrolysis oil is a promising renewable energy source. Due to the variety of biomass feedstocks, the bio-oils could contain a wide range of organic constituents which would provide unique corrosive environments for structural materials. A preliminary work exposed different...

...Mass Changes and Corrosion Products Characterization Mass change based on surface area is used to compare the corrosion susceptibility of samples, which is calculated using Equation 6 : The current pipeline operation is using diluents including natural gas condensate and fully upgraded synthetic...

...corrosion crude pyrolysis oil iron-based steels transportation and storage Abstract Crude pyrolysis oils can be produced from different forest and agriculture feedstocks via fast, intermediate or slow pyrolysis processes. Although the oils have promising potential for clean energy production...

... cured for one week in ambient conditions prior to accelerated corrosion testing. Panels were scribed according to ISO 12944-6 with a 2 mm wide, 25 mm long scribe. ⁹ Panels were subjected to either 1000 (for system 1) or 1500 (for systems 2a and 2b) hours of ISO 12944-6 continuous neutral...

... electrochemical tests was also performed to understand the corrosion mechanisms and relate them to the microstructures and process parameters. The results from this study are presented in this paper. Alpha-beta titanium alloys Electron Beam Melting corrosion microstructure AM Additive Manufacturing...

...ABSTRACT The effect of build orientation on the corrosion resistance of 304L stainless steels (UNS S30403) produced by selective laser melting, was studied. Alloy coupons were obtained using three different build directions (vertical, horizontal, and 45° incline). The microstructures...

... corrosion in tubing and further aggravate the scaling issues. Abstract The waterflood development was adopted in a carbonate oilfield in the Middle East to enhance oil recovery. The injection water has high salinity and high Ca²⁺ concentration, which lead to scale deposition in the wellbore...

...Abstract Biomass hydrothermal liquefaction (HTL) is usually operated in harsh environments due to the presence of hot pressurized water reaction medium, alkaline catalysts, inorganic and organic corrosive constituents released during the conversion. Corrosion knowledge gaps exist on the selection...

...Corrosion occurs due to microbes, oxygen, and under-deposit conditions. ⁴ The source of water, presence of solids, temperature, and dissolved oxygen concentrations affect the corrosion tendency of hydrotest water. ⁴ Many times one has to use brackish water for hydrotesting...

... are difficult to remove in the desalter, and small amounts of both compounds get concentrated in the water phase of the crude column overhead, increasing the risk of overhead corrosion and fouling. It is very difficult to measure improvement in extraction of these compounds in the desalted crude...

... difference was read between the two inner pin electrodes. A set of 2, 4, 6, 8, and 10-foot pin spacing measurements were taken. The data is shown in Table 1 . Soil resistivity measurements revealed that soil around the pipeline is corrosive as per Table 2 . LABORATORY INVESTIGATION Soil Analysis Abstract...
