Use Of Potential Probes To Monitor Cathodic Protection: Accuracy Of The IR-Free Potential Measurement

Product Number: 51321-16765-SG

Author: Marco Ormellese

Publication Date: 2021

$20.00

Cathodic protection (CP) is an electrochemical corrosion prevention technique, which is implemented by circulating a direct current between an electrode (anode) placed in the environment and the structure to be protected (the cathode): this current causes a lowering of the potential of the metal and reduces its corrosion rate, until it stops.

Using DC Decouplers to Maximize Isolation of Cathodically Protected Structures

Product Number: MECC23-19878-SG

Author: Jay Warner

Publication Date: 2023

$20.00

Cathodic Protection (CP), when properly applied, is an effective technique to minimize the natural corrosion process that occurs on pipelines, tanks, and other buried steel structures. To maintain effective CP coverage with minimal current demand, the structure must be well-isolated from earth for DC current flow. This is commonly accomplished using high resistance coatings, isolation joints, dielectric fittings and isolation pads.

Vintage Pipeline Enhanced Corrosion Management Analysis

Product Number: 51324-21127-SG

Author: Kenton Lawson; Jason Charles Land; Angel R. Kowalski

Publication Date: 2024

Vintage pipeline operators face increased regulatory challenges. These aging pipeline systems may have decades of metal loss and coating damage from soil interaction, pressure cycling, thermal stresses, and other physical phenomena that affects the pipeline’s mechanical integrity to make it more susceptible to leaks or ruptures. Aging pipeline systems are candidates for Enhanced Corrosion Management Analysis (ECMA) to effectively mitigate corrosion risks. The ECMA methodology begins with the integration and analysis of available corrosion control monitoring, maintenance, inspection, and assessment data, to identify the need to collect additional data. When all data deemed necessary to conduct ECMA is available, an analysis is conducted to identify the possible causes of corrosion metal loss in the pipeline system, e.g., inadequate cathodic polarization, poor or disbonded coating conditions, electrical shielding, stray current interference, or microbiologically influenced corrosion (MIC). Effective mitigation plans are then developed to address most probable causes of corrosion metal loss and integrated into the corrosion management program. A case study is presented to demonstrate the implementation of ECMA on a vintage pipeline system and the development of a 20-year corrosion mitigation plan to effectively minimize the corrosion risk on the pipeline. The case study also illustrates how engineering economic analysis can be used to guide decision making regarding operational life extension of the asset and how a well-planned corrosion management program can provide cost-effective, safe operation over the lifecycle of the pipeline.

Visualizing Correlations of Water Quality and Cathodic Protection Parameters

Product Number: 51323-19333-SG

Author: Veronica Lynn Gerios, Natalie Becerra-Stasiewicz, Sean Morefield, Cristina Fleig Mayer

Publication Date: 2023

$20.00

Corrosion is responsible for the deterioration of steel structures over time. Thus, there are billions of dollars lost each year worldwide, due to leakage of materials transported in metallic pipelines, as well as the need for repair and replacement of materials. Cathodic protection is one of the main ways to minimize or even suspend the corrosive process, along with the application of protective coatings on metallic structures.

Well Casing Cathodic Performance Review - Case Studies

Product Number: 51322-17688-SG

Author: Maryam Al Hashmi, Monica Fernandez, Hamed Al Habsi, Naveed Munir, Fatih Boluk

Publication Date: 2022

$20.00

Oil and gas wells represent a large capital investment. It is imperative that corrosion of well casings be controlled to prevent loss of oil and gas, environmental damage, and personnel hazards, and in order to ensure economical depletion of oil and gas reserve. Wells placed in external corrosive environment shall be protected by appropriate barriers such as additional cemented casing, cathodic protection and coating to assure well casing integrity.

Yeah, Examining the Impact of Overprotection on AC Corrosion: A Case Study Investigation

Product Number: 51324-20877-SG

Author: Ivano Magnifico

Publication Date: 2024

$40.00

The risk of AC corrosion has always been linked in particular to the parallelisms of underground pipelines with HVAC lines, especially in those geographical areas where the morphology of the territory creates obligatory so-called "technological corridors", and therefore forces the coexistence of different services over long distances. More recently, the greater diffusion of AC-powered railway networks has further increased the AC interfering sources, while the use of more performing coatings on underground pipelines has on the one hand increased their insulation from the surrounding soil, and on the other has increased the risk of overprotection compared to old, less performing, or more degraded coatings. This paper, starting from a real case found in a gas distribution network in a European big city, will present the normative criteria to be used to keep the AC corrosion risk under control, and will highlight how precisely the simultaneous presence of cathodic overprotection may result in an autocatalytic cycle leading to accelerated AC corrosion, in which monitoring becomes essential in order to be able to carry out on time the appropriate corrective actions.
