Comparison of Two ASTM E1820 Standard Fracture Toughness Test Methods for LAS Material in Deaerated Saltwater under Cathodic Protection

Low alloy steels (LAS), frequently used for pressure-containing equipment in subsea applications, are susceptible to hydrogen embrittlement when exposed to seawater environments under cathodic protection (CP), which can result in a reduction of toughness and ductility. Fracture toughness, which is an indication of a material’s resistance to crack propagation and unstable crack growth, is often determined from laboratory tests for design verification analysis or fitness-for-service applications. In hydrogen charging environments such as deaerated saltwater under CP, the fracture toughness is typically measured using either an unloading compliance (UC) or a rising displacement DCPD test method, both of which are described for air testing in the current ASTM E1820 standard. In this study, slow load rate fracture toughness tests on compact tension C(T) specimens using both test methods on the same heat of material are performed and compared. The tests are performed in a deaerated saltwater under CP environment using the same targeted K-rate of 0.005N/mm3/2/s. The UC test method is performed with a clip gauge for load-line displacement (LLD) and in-situ crack depth measurement, and the rising displacement DCPD test method infers LLD indirectly and uses DCPD for crack depth prediction. A comparison of the test results indicated a 35-65% increase in the calculated ???????? fracture toughness of the material when using the rising displacement DCPD test method.

Corrosion issues in the conversion of vegetable and waste oils to produce biofuels

Product Number: 51323-19308-SG

Author: Fouad Andari, Jean Kittel, François Ropital, Joana Fernandes, Laure Dodelin

Publication Date: 2023

$20.00

To limit the impact of greenhouse gas emissions on climate change, the use of conventional hydrocarbons needs to be reduced significantly. The global demand for biofuels is thus expected to grow during the present decade. Hydrogenated Vegetable Oil (HVO) is one of the predominant biofuels produced by converting lipidic feedstocks (vegetable oils, animal fats, waste cooking oils, …) through a conventional refinery hydrotreatment (HDT) process.

Development of an F22 Metal Compatible Scale Inhibitor for Subsea Application

Product Number: 51323-19069-SG

Author: Chunfang Fan, Wei Zhang, Tiffany Nguyen, Jason Moses, Alexander Nelson, David Orta

Publication Date: 2023

$20.00

Mineral scale deposition is one of the major flow assurance issues for the oil and gas industry. When an oil or gas well produces water, there is the possibility that scale could form either by the mixing of incompatible waters forming oversaturated brine or by direct precipitation of the water that occurs naturally in reservoirs due to the changes in pressure, temperature, or pH. Scale inhibitors are commonly used to prevent mineral scale formation during oil and gas production and mitigate this flow assurance issue.

Domain Diagrams for the Sulfide Stress Cracking Resistance of High Strength Low Alloy steel 41xx Bar Stocks

Product Number: 51320-14590-SG

Author: Vipul Shinde, Manuel Marya

Publication Date: 2020

$20.00

High-strength low-alloy steel bar stocks with 110ksi (758MPa) and 125ksi (862MPa) specified minimum yield strength (SMYS) are in demand for temporary and permanent downhole tools for sour service. NACE MR0175/ISO15156 currently allows the use of low-alloy steel bar stocks without any environmental restrictions up to 22HRC, which, by most specifications, corresponds to 80ksi (552MPa) SMYS. At higher SMYS, and with exclusions of API and proprietary sour tubular grades, NACE MR0175/ISO15156 does not address solid bar stocks, a gap and opportunity addressed by this investigation. Specifically, in this paper, the sulfide-stress cracking (SSC) of commercial UNS G41xxx (41xx) alloys, including 41xxMod (i.e., carefully selected or mill modified) is investigated following a series of NACE TM0177 Method A tests in either Solution B or A (NACE Region 3). Domain diagrams for 41xx alloys are disclosed, all demonstrating that 41xx solid bar stocks are SSC resistant above 150°F (66°C) when under a new and improved specification. When SMYS is raised to 125ksi (862MPa) with 34HRC max, a safe minimum temperature of 175°F (79.5°C) is confirmed for hollow bars, well in line with current NACE MR0175/ISO15156. The metallurgical and hardness requirements of 41xx alloys are also briefly discussed, along with opportunities for further modifications of 41xx bar stocks.

Effect of Dissolved Oxygen on Fatigue Crack Growth Rate of Low Alloy Steels in Saltwater with Cathodic Protection Environment

Product Number: 51323-18913-SG

Author: Arshad Bajvani Gavanluei, Jenny Crump, Joseph Wilhelmi, Jack Smith, Paul D. Bunch

Publication Date: 2023

$20.00

Low alloy steels (LAS) are widely used in the marine and offshore oil and gas industry for various applications from bolting to large pressure containing heavy wall forgings. These materials are subject to various types of corrosion (general or uniform, pitting, crevice, etc.) and degradation in seawater environment. However, their selection for the applications, in comparison with stainless steels and corrosion resistant alloys, is justified due to their availability, manufacturability, proven service history, and lower cost.
