Case histories where throttling down the cathodic protection was evaluated to determine the impact on reducing the AC corrosion threat. Includes the use of fast-response electrical resistance corrosion rate probe monitoring technology.
Conductive and static dissipative floorings and coatings are designed to provide protection from electrical charges causing harm to work or products. This presentation is designed to familiarize you with the phenomenon of Static Electricity, how it is generated and its effects on industry. We will then discuss ways to alleviate or restrict problems associated with ESD by utilizing specialized conductive or static dissipative flooring and coating products. Specifically focused on the common conditions and design considerations required for a proper installation, including substrate requirements, grounding and strapping recommendations, and product selection criteria.
Atmospheric corrosion monitoring has traditionally been a lengthy and costly discipline. Visual inspection and weight loss testing is commonly applied, and this requires years of testing and on-site inspections with regular intervals. Furthermore, inspections and surveys in marine environments are troublesome, expensive and sometimes dangerous.
Remote monitoring of corrosion and cathodic protection using various methods have matured for decades with the onshore pipeline industry. With increasing activity offshore, and the highly corrosive and inaccessible environment taken into consideration, it is only natural that remote monitoring technology will find its way into this field. Offshore structures of steel are protected against corrosion with protective coatings and/or cathodic protection.
Injection water/brine handling systems are important elements of the oil & gas field operations. This comparative study offers insights relevant to accuracy, sensitivity and responsiveness of different corrosion monitoring techniques in brine environment.
