A New Method for Studying Erosion Corrosion in Flowing Fluids

Product Number: 51319-12954-SG

Author: YongJun Tan

Publication Date: 2019

$20.00

In this work a new sensor system was developed based on an electrochemically integrated multi-electrode namely the wire beam electrode in conjunction with an electrical resistance (ER) method. This new method has allowed galvanic currents flowing among the multi-electrodes and the total metal loss simultaneously measured. On the basis of the new designed 10 elements sensor system corrosion in both static and flowing electrolytes were studied. From the comparison of the galvanic current and the ER measurement results it is seen that galvanic corrosion is the main contribution of the water-line corrosion in both static and flowing electrolytes.Yunze Xu1 Mike Yongjun Tan1* and Yi Huang21School of Engineering and Institute for Frontier MaterialsDeakin University 75 Pigdons Road Waurn Ponds VIC 3216 AustraliaSchool of Naval Architecture and Ocean EngineeringDalian University of Technology 2 LingGong Road Dalian Liaoning 116024 ChinaPresenter email address: xuyunz@deakin.edu.au*Corresponding author email address: mike.tan@deakin.edu.au

A New Method of Evaluating Corrosion-inhibiting Admixtures

Product Number: 51319-13434-SG

Author: Casey Heurung

Publication Date: 2019

$20.00

The quintessential standard for evaluating corrosion-inhibiting admixtures and their effects on a cement mix is ASTM C1582. This standard relies on ASTM G109 and ASTM G180 to determine the admixture's impact on corrosion rate in concrete. Unfortunately these tests come with several intrinsic issues that limit their use and consistency. Importantly ASTM G109 runs for several years and ASTM G180 has an experimental precision of one magnitude. At this time ASTM G180 remains the most favorable test to perform regardless of its innacuracy because it only requires roughly three days of experimentation.This report will evaluate an ASTM G31 (Standard Guide for Laboratory Immersion Corrosion Testing of Metals) test run in similar conditions to ASTM G180. Immersion testing typically yields precise results and since ASTM G180 is already an immersion test evaluated by electrochemical methods a similar ASTM G31 test has the potential to afford comparable results that are easier to understand and utilize while still maintaining higher precision.

A New Method to Mitigate Halite Deposit by Using Non-Water-Soluble Quaternary Ammonium Corrosion Inhibitor

Product Number: 51324-20867-SG

Author: Dong Shen; Kung-Po Chao; Joseph E Penkala

Publication Date: 2024

Halite scale inhibition is one of the most challenging issues in the industry as oil and gas are produced in a high salinity brine environment. Although currently the best practice in the field for halite scale mitigation is to inject fresh water to dilute the halite scaling brines, it is not practical in locations where a nearby source of good quality fresh water is inadequate. Therefore, many studies have been conducted to investigate the chemistry and performance of halite scale inhibitors. The most common halite inhibitors, such as NTAA (nitrilotriacetamide) and potassium ferrocyanide (K3Fe(CN)6), are water soluble compounds. Recently, we discovered a non-water-soluble quaternary ammonium compound, commonly used as a corrosion inhibitor, is able to prevent the salt deposits effectively. Laboratory testing results indicated that the inhibition performance of this quaternary ammonium was similar to NTAA when the treatment dosage is less than 2000 ppm. Field observations also revealed this corrosion inhibitor demonstrated effective halite inhibition properties. Wells in high salinity areas treated with the quaternary ammonium did not require freshwater treatment to manage the halite scale issue, while wells in the same operating area that were treated with conventional corrosion inhibitors did require freshwater treatment.

A New System of Corrosion Flow Loops and Some Experimental Results

Product Number: 51320-14435-SG

The control of multiphase flow corrosion in oil and gas industry is one of the biggest challenging tasks. Since the 1990s, several organizations have established and operated large-scale flow loops to simulate and reproduce the field service environment of oil and gas pipelines. Based on comparison and investigation of the above loops, a new and advanced system, including several four inches internal diameter loops for studying corrosion under multiphase flows, was successfully built by us. By using this system, multiphase flows with various combinations of gas, water, oil and sand can be realized at the highest temperature of 140 oC and the highest pressure of 10 Mpa. Moreover, some loops in this system can adjust pipeline at different angels from 0 to 90°, which allow horizontal/vertical/sloping conditions to be simulated in laboratory. Many advanced measuring and monitoring technologies, such as Particle Imaging Velocimetry (PIV), high speed video camera and LPR/ER probe, are employed for simultaneously recording flow events and corrosion rates. An inhouse plane three-electrode probe is employed for conducting in situ electrochemical measurements. Such technologies would allow deep researching of corrosion behaviors and mechanisms in multiphase flow environments. Moreover, a new software based on Fluent and the existing multiphase corrosion models was developed to realize the numerical simulation of multiphase flow in loop.

A Novel Approach to Assessing Stray Current Interference without Potential Interruption

Product Number: 51324-20452-SG

Author: Parker B. Robbins

Publication Date: 2024

$40.00

A novel approach is proposed to assess a procedure for testing whether a pipeline may be interfered with from DC stray current. With the rise in popularity of portable coupons in AC mitigation testing, the paper proposes a method to evaluate DC stray current with a portable or stationary coupon without requiring potential interruption on foreign structures. This may allow technicians to conduct additional testing on suspected interference spots without requiring the interruption of a foreign pipeline or structure. This paper outlines and proposes a procedure for determining the likelihood of DC stray current interference utilizing coupons. Additionally, the paper recommends and outlines a proposed study to assess the accuracy of the techniques in the proposed procedure. While DC current cannot typically be measured and quantified for a bare metal holiday on a pipeline, coupons allow for a controlled and measurable connection to a simulated pipeline holiday. The procedure may be utilized to distinguish when suppressed potentials are occurring on a pipeline as a result of DC stray current interference rather than from inadequate current provided by CP system, a foreign voltage gradient, shielding or electrical grounding, even when the source of current is unknown. The procedure may also be beneficial in situations with atypical interring-structures where the existence of the interfering structure is unknown or where the applied voltage of the interfering structure cannot be interrupted traditionally such as with the prevalence of DC current situations occurring from installed or newly repaired direct-buried communication utility cables with weak splices at unknown locations. The procedure may also be utilized as an initial step to determine first steps in a DC stray current interference situation.

The concrete biological shields (CBSs) of light water reactors are affected by neutron and gamma irradiation at high radiation doses, resulting in the degradation of the concrete’s material properties. Several studies in the literature focused on evaluating both the expansion of aggregate-forming minerals and the resulting loss of mechanical properties. Modeling efforts have been carried out to predict the
radiation-induced volumetric expansion (RIVE) and damage using different numerical methods such as the finite element method or fast-Fourier transform (FFT).
