...Abstract The present study evaluated nickel-based corrosion resistant alloys (CRAs), used as fasteners in simulating “splash zone” region under cathodic protection (CP). The CRA’s were submitted to crevice corrosion and the influence of CP was assessed electrochemically. The testing apparatus...

...Abstract The rectifier groundbed is a key component of an Impressed Current Cathodic Protection (ICCP) system in that it is consumed over time. The rate of consumption is based on many contributing factors including anode mass and material, surrounding soil properties, seasonal effects...

...Abstract Although cathodic protection (CP) has been widely used for general corrosion prevention, conventional CP does not have the capability of adjusting its protection potential and current levels based on changing corrosion conditions and mechanisms, therefor conventional CP can have issues...

...Abstract Alloy 718 is commonly used in the upstream oil and gas industry for multiple applications that are exposed to wellbore fluids and seawater with cathodic protection (SWCP). The alloy is prone to a hydrogen-induced stress cracking (HISC) risk if the influencing factors are not carefully...

...Abstract For pipelines equipped with both cathodic protection and coating coverage, cathodic disbondment has been recognized as a significant factor that adversely affects the long-term integrity of pipelines. Due to experimental constraints, developing a numerical model to study disbonded coating...

...Abstract The purpose of this study was to evaluate CP coupon ON, instant-off and native potentials in a waveform measured by an oscilloscope to evaluate the performance of the cathodic protection system. A CP coupon is a piece of metal that is manufactured from a material same...

...Abstract Steel can be susceptible to corrosion, the natural process by which metals degrade. Combining coatings such as polyurethanes, epoxies, and wrap sleeves, with a cathodic protection system provides an effective strategy for protecting and extending the design life of your asset. corrosion...

... 3.9 Abstract Cathodic protection (CP) is widely used to protect against soil-side corrosion of aboveground storage tanks (ASTs). However, design practices, field installations and implementations, and operational parameters can be suboptimal, leading to soil-side corrosion of the AST bottoms even...
