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.

A Comparison of the Pitting and Crevice Corrosion of Directional Drilling Alloys With Oilfield Production Alloys

Product Number: 51320-14432-SG

Author: Manuel Marya

Publication Date: 2020

$20.00

The pitting corrosion and crevice corrosion of oilfield production alloys (e.g., 13Cr/UNS S41000, 17-4PH/UNS S17400, 25Cr/UNS S32750, A286/UNS S66286, 718/UNS N07718) and proprietary austenitic stainless steels for directional drilling (PREN between ~20 to ~45) has been investigated. Specifically, series of electrochemical tests have been conducted to rank the alloys, establish simple correlations between electrochemical parameters, PRENmod, and 3-to-60-day immersion tests in 3.5% NaCl at ambient temperature. For all but one alloy, pitting was absent in stark contrast to crevices. Upon tracking populations and dimensional characteristics of crevices over time, trendlines comparing the susceptibility of the alloys towards crevice corrosion were established. Practical conclusions were reached, including the following: (1) 13Cr consistently developed crevices within days, (2) 17-4PH as well as all traditional directional drilling stainless steels developed crevices within one to five weeks, and, (3) neither 718, 25Cr, nor newer directional drilling alloys with both high nickel and high PRENmod showed any sign of crevices upon being tested up to 60 days. Through a variety of comparisons, this investigation also reveals useful technical directions for the development of new, economical, and fit-for-service Oil & Gas alloys for both production and drilling.

Carbon dioxide capture, utilization, and storage (CCUS) is part of decarbonization solutions to reduce green-house gas emissions, as exemplified by the growing number of capital expenditure projects worldwide.^1-2 In CCUS, the carbon dioxide (CO₂) is consecutively (1) captured at origin, such as power plants and natural gas production sites, (2) separated from other gases and impurities, (3) compressed, (4) transported through pipelines, and finally (5) injected into a storage site such as deleted hydrocarbon wells, saline aquafers, coal beds, underground caverns, or seawater.^1,3 Since the 1970s, specifically the first commercial carbon dioxide flooding in the United States (known as SACROC), carbon dioxide sequestration has been largely discussed in the context of enhanced oil recovery (EOR), not in the newer context of Sustainability. Nonetheless, substantial experience has been drawn from EOR, including for the selection of the right and economical materials.⁴ As reflected by the literature, past materials test programs have rarely given any attention to downhole jewelry alloys compared to tubulars or surface-infrastructure alloys, and consequently the track records for such bar-stock alloys are either inexistent or not readily available. ^5-7 This lack of apparent return-on-experience represents a knowledge gap against the prospect of a safe greenhouse gas control method; needless to say, it also justifies the requirements for reliable well integrity monitoring solutions in carbon dioxide sequestration wells.^8-9

Ni-based corrosion resistant alloys UNS N06035 and UNS N10362 were designed with the goal of withstanding some of the most aggressive environments found in various sectors of the chemical processing industry (CPI). These alloys have successfully found a niche in process-specific environments that are uncommonly aggressive, pushing the envelope for higher chemical processing efficiency, performance and durability.

N06035 alloy was designed to resist “wet process” phosphoric acid, which is used in the production of fertilizers.

Crevice corrosion is a geometrical-dependent type of localized attack that occurs in occluded regions where a stagnant and corrosive electrolyte is in contact with the surface of a passive metal^1,2. Crevices are present in all industrial designs and can lead to major failure since their detection is often challenging^3,4. Main strategies for the prevention and mitigation of crevice corrosion include design awareness and adequate materials selection⁵.

Effect of Temperature on Corrosion in Saturated Ammonium Chloride Solution

Product Number: 51324-20856-SG

Publication Date: 2024

The highly corrosive behavior of ammonium chloride (NH4Cl) is known to originate from its intrinsic hygroscopic nature. Refining and co-processing process units for biofuels are often exposed to highly concentrated NH4Cl solution either resulting from water vaporization from an HCl and NH3 containing solution when the temperature increases or salt deposition from vapor phase when the temperature drops. For the latter case, once it reacts with water vapor present in the process, the deposited NH4Cl salts forms a concentrated and corrosive solution through deliquescence (unlike in conventional refinery). Consequently, severe pitting and localized corrosion are reported in hydrogenation and fluid cracking units. Therefore, studying corrosion resistance alloys (CRA) compatibility in the presence of concentrated NH4Cl salt solution is crucial to mitigate corrosion in the process. This paper reports the experimental evaluation of corrosion resistance of different CRAs, based on corrosion rate and stress corrosion cracking, exposed to saturated NH4Cl solution in the temperature range of 130-220°C.
