... 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...

... oil and gas pipelines in North America. Internal, external, and stress corrosion cracking threats were comprehensively assessed considering historical records and several susceptible factors that were specific to each threat. The result of the integrity assessment is an evaluation of susceptible...

... components generated in the reaction on the containment materials can be difficult to predict. In particular, the mechanism of corrosion in the organic solvent may not be elucidated in detail until the process is in operation and it can be difficult to deal with corrosion at that time. This paper describes...

...Distribution A: Approved for public release. Distribution is unlimited.

... of these buildings is most commonly dictated by corrosion of the embedded reinforcing steel cause by carbonation. Challenges with carbonation comes down to dealing with the length of time before corrosion will be initiated and then how long it takes in the propagation phase before damage to the concrete occurs...

... ABSTRACT Predicting corrosion risks and developing inspection and mitigation plans form a vital part of any Integrity Management System (IMS). Most of the emphasis from operators is given to upstream and processing facilities, however, the facilities installed downstream, in particular...
