A Right Way To Calculate Pipe CP Potential Attenuation

Product Number: 51322-17599-SG

Author: John Yang, Jiulong Liang

Publication Date: 2022

$20.00

Shown on Figure 1 is a typical impressed current CP diagram. When the rectifier is first turned on, i.e. time t=0, there is no polarization yet. At that moment, the applied DC voltage is fully consumed by IR drops at anode (IRa0) and cathode (IRc0), plus original potential difference between anode and pipe (Eoca- Eocc). When t=0, the current is at the greatest value. Over time when polarization kicks in, due to adding polarization resistance, the current is gradually reduced.

A Road Map For Innovation In Microbiologically Influenced Corrosion (MIC) In The Gas Pipeline

Product Number: 51322-18204-SG

Author: America A. Padilla-Viveros, Rigoberto Arroyo-Cortez

Publication Date: 2022

$20.00

A recent review provided an overview of current microbiologically influenced corrosion (MIC) research. It established that despite extensive study and numerous publications, fundamental questions relating to MIC remain unanswered and stress the lack of information associated with MIC recognition, prediction, and mitigation (Little et al., 2020). On the other hand, bibliometric analysis on the MIC of engineering systems conducted a knowledge gap analysis to focus research efforts and to develop a roadmap for MIC research (Hashemi et al., 2018).

A Study Of The Depolarization Phenomena In Soils And Remanence Of Corrosion Protection After CP Interruption

Product Number: 51322-17649-SG

Author: Clémence Rogier, David Sellam, Tiphaine Lutzler, Laurent Henry, Ahmed Fakhry, Yves Zannier, Elisabeth Fleury, François Castillon

Publication Date: 2022

$20.00

Oil and gas buried pipelines are protected against corrosion by both organic coatings, a passive protection system, and cathodic protection, an active protection system. When coating defects occur, CP controls the corrosion of the exposed steel surface. From an operating point of view, cathodic protection interruptions can occur on the network during interventions, consignments, or technical problems. Literature indicates that during CP interruption the corrosion rate of the metal remains lower than its free corrosion rate. Application of CP confers a remanence of protection to the metal. The objective of this study is to determine the safe duration for cathodic protection interruptions depending on environmental and cathodic protection conditions.

A Theoretical Investigation On The Role Of Microstructural Particularities On The Hydrogen Embrittlement Of Nickel Alloys

Product Number: 51322-17718-SG

Author: Julia Botinha, Bodo Gehrmann, Helena Alves

Publication Date: 2022

$20.00

Precipitation hardened (PH) nickel alloys have been broadly used in various applications in the oil and gas industry thanks to its high strengths and outstanding corrosion resistance in several aggressive environments. Alloy 718 (UNS¹ N07718), Alloy 925 (UNS N09925), Alloy K-500 (UNS N05500), Alloy 725 (UNS N07725), and others are among the most used PH nickel alloys in the oil and gas industry. Despite of their known high corrosion properties, hydrogen embrittlement is one common failure reported by the industry for this class of alloys.

A Two-Stage Cathodic Protection System Combining ICCP Components with Long-Term Galvanic Anode Steel Reinforcement Protection

Product Number: 51323-18868-SG

Author: David Whitmore, David Simpson, George Sergi

Publication Date: 2023

$20.00

There is no doubt that Impressed Current Cathodic Protection (ICCP) of steel reinforced concrete has, over the last decades, become a well-established technique for controlling reinforcement corrosion of structural elements. The expectation of long-life protection has, however, been somewhat reduced as some anode systems fail, monitoring equipment become antiquated, and lack of adequate maintenance makes the systems inoperable with the average service life of any ICCP system falling to 15-20 years.

AC Mitigation Design Considerations for Pipeline Facilities

Product Number: 51323-18867-SG

Author: Hycem Bahgat, Sorin Segall, Ernesto Gudino

Publication Date: 2023

$20.00

When a pipeline is co-located with an AC powerline, it is subject to AC interference effects. These AC interference effects can result in safety hazards to operating personnel and the public under powerline steady-state (normal operation) and fault (short-circuit) conditions.

Acceleration Of 316L Stainless Steel Corrosion By Proton-Irradiation-Induced Displacement Damage In Hydrogenated Steam

Product Number: ED22-17134-SG

Author: Rigel D. Hanbury, Jonas K. Heuer, Gary S. Was

Publication Date: 2022

$20.00

From stress corrosion cracking of baffle-former bolts to radiological hazards from Co-60, corrosion of structural materials is the root of many operational issues that occur in light water nuclear reactors. Corrosion must be controlled to mitigate the risks of larger problems that reduce the operational time and lifespan of a reactor. One fundamental feature of nuclear reactors is the radiation field which is known to impact corrosion behavior. However, there is a severe lack of understanding the underlying mechanisms of radiation effects on corrosion, especially for stainless steels. Ion irradiation experiments allow for the controlled study of radiation effects on corrosion and to compensate for the lack of reactor data on structural materials.

Acceleration Of Long-Range Ordering in NiCrFe Alloys Using Proton Irradiation

Product Number: ED22-18352-SG

Author: Cole Evered, Nicholas Aerne, David J. Sprouster, Julie D. Tucker

Publication Date: 2022

$20.00

The extension of nuclear reactor lifetimes beyond 40 years requires the qualification of plant components to ensure performance past their initial design requirements. Nickel-based alloys containing chromium (NiCr) are of concern at these extended lifetimes, as these types of alloys form an embrittling precipitate phase. Below a critical temperature—which is above the normal 300-400⁰C reactor operating temperatures—NiCr alloys form a stable, fully coherent MoPt2-typelong-range ordered (LRO) phase with stoichiometry Ni2Cr.

Adhesion And Wear Resistance Of PVD Nitride-Based Coatings On Zircaloy Substrates

Product Number: ED22-17266-SG

Publication Date: 2022

The Fukushima Daiichi Accident in 2011, which was the result of the Great East Japan Earthquake, tsunami, and prolonged station blackout, increased the focus on developing accident tolerant fuel cladding (ATFC), especially on the use of protective coatings. Coatings have been widely used in a variety of industries, including automotive, aerospace, and nuclear to improve corrosion resistance, enhance hardness and physical properties, and reduce wear. In an accident scenario, a coating may aid in reducing the oxidation kinetics and hydrogen evolution rates. The present study investigates the benefits that physical vapour deposited nitride-based coatings may have for ATFC.

Advanced Coating Technology For Refinery And Petrochemical Applications

Product Number: 51322-17657-SG

Author: Sanjay Lodha

Publication Date: 2022

$20.00

The formation of carbon deposits and fouling of tubes is one of the most common operational issues regarding the operability and lifetime of materials at an industrial scale. Several billion dollars are spent worldwide on annual basis to upgrade/change materials apart from revenue loss on account of production halt and additional costs incurred in maintenances. Particularly, the carbon deposition in the refining process is an evitable and undesired factor. Most refineries worldwide have vacuum distillation, delayed cokers, visbreakers, or thermal cracking units where coke formation occurs faster due to high temperatures used in the process.
