04298 Corrosion Evaluation of a High Performance Cu-Based Alloy for Seawater Applications

Product Number: 51300-04298-SG

ISBN: 04298 2004 CP

Author: John O. Ratka, Brush Wellman Inc.; Manuel N. Maligas, FMC Technologies

Publication Date: 2004

$20.00

In seawater, higher strength nickel-copper alloys are used as alternatives to copper alloys. These can be susceptible to chloride stress corrosion cracking and hydrogen embrittlement in conditions where cathodic protection is utilized. Copper-Nickel-Tin alloys (CuNiSn) show low corrosion rates in the free and coupled conditions. Resistance to hydrogen embrittlement is demonstrated.

51317--9650-Effect of Biocides and Corrosion Inhibitors On SRB-Mediated MIC Under Flow Conditions

Product Number: 51317--9650-SG

ISBN: 9650 2017 CP

Author: Gerrit Voordouw

Publication Date: 2017

$20.00

Biocides and corrosion inhibitors can decrease corrosion in stagnant and flowing systems. We used 1 ml syringe columns packed with 60 carbon steel beads (55 mg each), which were continuously injected with the effluent of an sulfur reducing bacteria continuous culture chemostat, to monitor corrosion under flow conditions.

A Parametric Evaluation of Well Construction Corrosion-Resistant Alloys for Geological Carbon Sequestration

Product Number: 51324-20582-SG

Author: Manuel Marya

Publication Date: 2024

$40.00

A parametric test program involving completion alloys in supercritical CO2 was conducted using both isothermal and non-isothermal cycles in the presence of contaminants (i.e., H2O, NO2, SO2, H2S, H2) above typical impurity limits for carbon capture and sequestration (CCS). The isothermal testing consisted of 4500 psi (310 bar) autoclave tests at 175°F (79°C) with the test materials in supercritical CO2, and optionally, in a NaCl-rich brine in equilibrium; the non-isothermal testing was similar, but included three consecutive cycles with 250°F (121°C) and 70°F (21°C) exposures. Up to ten corrosion-resistant alloys [i.e., 9Cr (UNS K90941), 13Cr (UNS S42000), S13Cr (ISO13680 (1) Type 13-5-2), 15Cr (proprietary), 17Cr (proprietary, 22Cr (UNS S32205), 25Cr (UNS S32750), G3 (UNS N06985), 925 (UNS N09925), 718 (UNS N07718), and 716 (UNS N07716)] were tested for weight loss, pitting, and crevice corrosion. The alloys, known to be more susceptible to environmentally-assisted cracking (EAC), were also evaluated for cracking with ppm-levels impurities (25-to-150 ppmv each), including hydrogen sulfide (H2S). Alloys 22Cr, 25Cr, and API (2) Spec. 6A and Std. 5CRA nickel-based alloys are generally found to be fit-for-service for subsurface CCS. In contrast, the alloys with 9-to-17 wt.% chromium tend to suffer from pitting, which when extensive, has been associated with a case of EAC. For the pitting-resistant alloys under test, neither EAC nor crevice corrosion created major new risks. The introduction of non-isothermal cycles to qualify alloys for CCS has successfully emphasized the dominant effects of condensates, otherwise under-represented, and is suggested for future material testing and qualification programs.

Development of Test Sites in Alaska to Study Atmospheric Corrosion Using Adjustable Test Racks

Product Number: 51324-21000-SG

Author: Raghu Srinivasan; Jozef Hunter

Publication Date: 2024

$40.00

In colder regions, heavy snowfall and pronounced freeze-thaw cycles introduce complexities to the established paradigms governing atmospheric corrosion. To elucidate the mechanisms of atmospheric corrosion under Arctic conditions, four distinct corrosion test sites were established in Alaska, each representing a unique corrosive environment. Each site was equipped with a modern, multi-angle corrosion exposure test rack coupled with an auxiliary weather station. Two additional multi-angle racks are introduced, offering enhanced flexibility and efficiency in research deployments. Innovation is in the design of modular corrosion test racks that can be adjusted to three different exposure angles. Within these setups, five different metal alloy specimens were exposed at three different angles and different lengths of time. Following exposure, the specimens underwent analysis to determine corrosion rates and weather parameter correlations.

Offshore Marine Corrosion Rates - A Case Study

Product Number: 51322-17977-SG

Author: Alex Delwiche, Patrick Lydon

Publication Date: 2022

$20.00

In the UK a huge effort was made in the mid to late 2000’s to minimize carbon emissions and the country had seen a rapid increase in wind-turbine generators being installed onshore and increasingly in offshore waters, nearly 2000 were operating in September 2018 and many more are expected in the coming decades. 1 One operator took the challenge to install a number of wind-turbines in the southern sector of the North Sea, just off the coast of south east England. These wind-turbines are constructed using the monopile foundation type principle.

Water Treatment Dosage Control and Relationship to Performance

Product Number: 51395-95260-SG

Author: J.E. Hoots

Publication Date: 1995

$20.00

New methods for monitoring scale and corrosion inhibiting water treatment programs have been developed. These new patented methods utilize the measurement of system consumption of actives in the treatment program by fluorescence analysis.'-' The applied dosage of treatment program and the amount of actives available to the system are measured with inert fluorescent tracers added to the treatments.

System consumption of actives is defined as the difference between the amount of actives added and remaining in the system. 2,5- 7 Consumption measurements determine changes in the whole operating system (not a simulated, small portion of the system). Consumption measurements can also be made on individual portions of the system (heat exchangers). Changes in consumption of inhibitors and dispersants can .be related to changes in system operating conditions and performance. Reducing consumption of actives or maintaining consumption within a specified range can be related to optimization of the operation of the cooling system and treatment program.
