Review Of Coating Current Test Methods For Simulating CUI Conditions And Introduction Of A New, Small Scale, Accelerated Test Method

Product Number: 51322-18173-SG

Author: David Morton, Ulrik Bork, Vadimas Verdingovas, Simon Daly

Publication Date: 2022

Corrosion under Insulation (CUI) costs industry millions of dollars. Water ingress into conventional insulation systems can result in accelerated corrosion of the steel substrate w hich, if unchecked, will result in structural failure of the vessel or pipe. If the structure is operating under high pressure then this failure would be catastrophic. CUI can result in significant loss of revenue from downtime, maintenance and replacement of corroded structures.

The Hanford Nuclear Reservation contains radioactive and chemically hazardous wastes arising mostly from weapons production, beginning with World War II and continuing through the Cold War. The wastes are stored in 177 carbon steel underground storage tanks, of which 149 are single-shell tanks (SSTs) and the remaining are double-shell tanks (DSTs). The U.S. Department of Energy, Office of River Protection is responsible for retrieving the tank wastes, treating them in order to encapsulate them in glass logs, and then permanently closing the tanks and associated facilities.

Review Of The State Of The Art Of Siliceous Scale Management In Industrial Systems

Product Number: 51322-17731-SG

Publication Date: 2022

Fouling of equipment surfaces by siliceous salts such as silica, metal silicates,
coprecipitated silica with mineral salts such as calcium carbonate, calcium sulfate, etc.,
is a serious challenge facing the technologists in the efficient operation of industrial
systems. Severe fouling at times results in premature expensive equipment replacement,
early shutdown, increase in operating pressure of pumps, and enhance the probability of
corrosion damage. In many cases, the removal of foulants leads to discontinuous
operation of the system, resulting in higher operating costs. In geothermal applications,
siliceous scale typically occurs when brine is cooled in the course of brine handling and
energy extraction.

Revisiting The Anodic Dissolution Of Pure Iron In Strong Acid: Replication Of Bockris’ Estimation Of Butler-Volmer

Product Number: 51322-17681-SG

Author: Mohiedin Bagheri Hariri, Bruce Brown, Srdjan Nesic

Publication Date: 2022

$20.00

Reviewing literature related to corrosion research brings to light the importance of understanding the mechanisms involved, and how this is essential to aid in development of mathematical models for corrosion prediction. The current research documents possible mechanisms for the dissolution of pure iron in strong acid in a potential range in the potential range of ±50 mV vs. OCP, providing explanations for corrosion engineers and researchers working with mild steel. Prediction of corrosion rate relies on the precise understanding of the anodic and cathodic processes at the metal surface in the potential range close to the OCP.

Risk Evaluation Of Potential Coating Damage From HDD

Product Number: 51322-17762-SG

Author: Ron Raphoon

Publication Date: 2022

$20.00

This paper will identify the potential causes of pipe coating failure, from the design angles to the soil types, to the fracture methods of rocks, and pull forces. It will present a logical method for evaluating the condition of an HDD pull prior to its installation so that the right level of coating protection may be applied. The pipelines that carry our world's energy and industrial networks are a vital lifeblood of our society. HDD’s play such an integral part in keeping all aspects of the pipeline and its construction running smoothly, the aim here it to ensure there are no hiccups along the way.

Robust Non-Phosphorus Cooling Water Treatment Program That Reduces The Biological Control Challenge - A Case Study

Product Number: 51322-17626-SG

Author: Bingzhi Chen, Yikun Guo, Xiao Zhang, Ben Brock, Jessica Grailer

Publication Date: 2022

$20.00

Cooling water systems are commonly used to cool a process, either steam, gas or liquid, through heat exchangers or condensers in various plants. The heat exchangers or condensers can be corroded easily or have scale and biofilm growth due to the poor water treatment program. The corrosion, scale, and biofilm growth on heat exchangers can lead to significant reduction in heat exchanger efficiency and lifetime. The repair expense or loss of production often costs plants a few hundred thousand or millions of dollars per day for heavy industries, such as chemical and power plants, refineries, and steel mills. Thus, cooling water treatment is critical to maintain the integrity and efficiency of heat exchangers.

Role Of Acetic Acid On The Kinetics And Mechanism Of Carbon Steel Dissolution Under CO2 Top Of Line Corrosion

Product Number: 51322-17818-SG

Author: Mariana Costa Folena, José Antônio da Cunha Ponciano Gomes, Frederick Pessu, Anne Neville, Richard Barker

Publication Date: 2022

Top of line corrosion (TLC) is a specific corrosion mechanism observed in the oil and gas industry. This phenomena occurs under stratified or wet-gas flow regimes when the upper internal pipeline walls are sufficiently cooled (by heat transfer to the surrounding outer environment), promoting local condensation of water vapor. Carbon dioxide (CO₂) and organic acids dissolving into the condensed water generate a change in the solution chemistry, ultimately influencing the corrosion kinetics of the contacting carbon steel.

SCC Initiation and Growth Rate Response of A-286 in B/Li and B/K Solutions 340°C

Product Number: ED22-17262-SG

Author: P.L. Andresen, P. Chou

Publication Date: 2022

$20.00

Stress corrosion cracking (SCC) initiation and growth rate testing was performed using Alloy A-286, a high-strength iron-base alloy, to evaluate for possible differences in response in boric acid solutions containing KOH vs. LiOH. PWRs are considering a switch from LiOH to KOH because of the uncertain future availability and high cost of Li. To achieve the same pH at temperature (pHT) in typical PWR primary water, the same molar concentration of Li and K is needed. The atomic weight of K is 39.1, which is 5.63 higher than the atomic weight of Li at 6.94, so 1 ppm Li yields the same pHT as 5.63 ppm K. The conductivity differs somewhat because of difference in the mobility of Li+ and K+.

SCC Of Tensile Wires At High CO2 Partial Pressure In Simulated Annulus Environments Of Flexible Pipes

Product Number: 51322-17898-SG

Author: Pedro Netto da Silva, Gaute Svenningsen, Arne Dugstad, José Antônio da Cunha Ponciano Gomes

Publication Date: 2022

$20.00

Unbonded flexible pipes used for transporting process fluids in offshore oil and gas production systems have a complex structure, with alternate polymer and metallic layers. Tensile armors are metallic layers constructed by the helical wrapping of high strength carbon steel wires, and they are responsible for the integrity of the pipe. These armors provide axial strength and torsion resistance to the pipe so that it can sustain its own weight and resist to stresses associated to environmental conditions and vessel motion.

Severe Pipe Damage In SAGD Steam Distribution Lines

In Oil Sands In-Situ operation bitumen is often extracted from underground oil sands deposits through SAGD (Steam Assisted Gravity Drainage) technology. This method involves forcing steam into sub-surface oil sands deposits, usually those at depth greater than 150m (492 ft), to heat the bitumen locked in the sand, allowing it to flow well enough to be extracted [1]. This process technology makes it possible to access the underground deposits otherwise difficult to access through the open mine method. It is particularly relevant in Canada because it is the most common method of in situ extraction used in the oil sands.
