.... Such challenges stem from multiple operational factors, including changing process feed, driven by opportunity crudes and throughput, need to work with more complex process dynamics and difficulties associated with correlating potential corrosion damage to process parameters across different refinery units...

... ABSTRACT Top of the Line Corrosion (TLC) is now known to be the main mode of failure in incidents associated with a number of wet gas pipelines operated all over the world. TLC is nevertheless a relatively recent phenomenon in a sense that its existence was only acknowledged about 10 to 15...

... ABSTRACT Preferential weld corrosion offers a uniquely different challenge to operators of high throughput oilfield production in carbon steel pipelines. This has a significant impact on the expected lifetime of the pipeline and, thus, will require chemical inhibition programs to mitigate...

... ABSTRACT Accelerated corrosion of tens of thousands of aging transmission structures in electric power transmission lines is a leading cause of in-service equipment degradation. Each year, utility companies spend an increasing amount of their revenue on inspection and refurbishment...

... ABSTRACT The corrosion resistance of copper-nickel 90/10 and 70/30 tubes for heat exchangers was evaluated in 0.5 ppm-chlorinated seawater, under controlled service conditions in a bespoke test loop. The results were compared to Al-Brass tubes tested under the same conditions. Copper-Nickel...

... ABSTRACT Drop evaporation test at three different temperatures was conducted with duplex stainless steel for studying the influence of temperature, strain and heat input on its stress corrosion cracking (SCC) suitability. Three welding conditions were performed: regular heat input of 1.0 kJ...

... ABSTRACT INTRODUCTION Improvements in refinery crude blending, injection of inhibitors, and deacidification of stream distillation (neutralizers) practices Selection of better materials of construction utilizing corrosion resistant alloys (CRAs) and surface modification (coatings...

... and predict pipeline corrosion rate. One type of model that attracts attention in recent years is probabilistic models especially those created based on Bayesian Networks. Bayesian Networks is particularly well suited to help the DA process because the methodology allows combining mechanistic models...

... Abstract Zinc has been used to protect ferrous materials against corrosion for many years. Metallized arc-spray zinc coating is now available on ductile iron pipe produced in the United States and has been widely accepted and specified since its domestic advent several years ago. This paper...

... ABSTRACT A compact and autonomous corrosion sensor using the principle of electrical resistance variations of its metallic sensitive tracks has been used for different applications under atmospheric corrosion conditions. The measurements of the corrosion rate are performed in-situ both...

... ABSTRACT Carbon steels are widely used in the oil and gas exploration and production service. However, these materials are prone to corrosion and cracking in CO 2 /H 2 S. The propensity to cracking increases when higher strength grades are employed. The use of corrosion resistant alloys...

... ABSTRACT A previously developed modeling framework has been extended to predict the general and localized corrosion of various corrosion resistant alloys (CRAs), including alloys 2507, 2535, 28, 29, S13Cr, S15Cr, and S17Cr in complex aqueous systems relevant to oil and gas production...

... ABSTRACT The approach to asset degradation due to corrosion in commodity mining is often seen as ‘something we have to live with’. There is a wide variety of unique degradation challenges associated with mine sites; often associated with the use of lower quality water sources for processing...

... ABSTRACT Aboveground storage tanks (ASTs) are widely used in the oil and gas and nuclear industries. These are typically constructed of carbon steel bottoms and shells, with the bottoms susceptible to corrosion. Corrosion control measures include cathodic protection (CP) systems, various...

... ABSTRACT Predictive models: Corrosion rates can be obtained from predictive models considering various operating scenarios, i.e., before the onset of corrosion. Monitoring probes: Corrosion rates can be obtained from online monitoring probes as corrosion starts; due for example...

... ABSTRACT ABSTRACT A Ni-P coating was applied to coupons made from a common valve stem material (AISI 4140) used in geothermal steam that was known to experience localized pitting corrosion in the valve stem packing area. The coated coupons were exposed in geothermal steam test chambers...

... ABSTRACT Carbon steel remains the most commonly used material in oilfield applications. The susceptibility of carbon steel to various forms of corrosion is one of the major drawbacks to its economic and metallurgical advantages. The formation of Iron Sulfide (FeS) corrosion product is common...

... ABSTRACT This paper summarizes multiple time-dependent pipeline integrity assessment case studies that were recently conducted on different oil and gas pipelines in North America. Internal, external, and stress corrosion cracking threats were comprehensively assessed considering historical...
