Development of 27–7MO: An Improved Superaustenitic Stainless Steel With High Strength and Excellent Corrosion Resistance for Sour Service

Product Number: 04114-SG

Material selection for downhole applications has become more difficult as the number of alloys continues to increase. On one hand, stainless steels like 316 offer a relatively low initial cost, but are not suited for many severe applications or environments. Other alloys, like MP35N, offer considerable strength and corrosion resistance, but with a much higher cost. Thus, an attempt has been made to create an alloy that spans the considerable gap between the 300 series of stainless steels and the nickel or cobalt base alloys. The resulting 6% Mo stainless steels offered increased strength and corrosion resistance without a drastic cost increase. The first generation of superaustenitics still falls considerably short of the strength and corrosion resistance provided by established nickel or cobalt-base alloys. In an attempt to further bridge the remaining gap, a new superaustenitic stainless steel has been developed that maintains the attractive cost of the 6% Mo alloys, but enhances both corrosion resistance and strength to open up environments that were too severe for 6% Mo alloys. The development of this alloy along with localized corrosion resistance, qualification testing, and mechanical testing are discussed.

Effect of CO in Stress Corrosion Cracking of Carbon Steel Pipelines in CCS Environments

Product Number: 51324-20647-SG

Author: Gaoxiang (Garret) Wu; Jose Rafael Vera; Ken Evans; Chong Li; William Kovacs

Publication Date: 2024

$40.00

Carbon monoxide (CO) is one of various possible impurities in carbon capture and storage (CCS) streams. As a by-product of the methane reforming process to produce blue hydrogen, CO is combusted and converted to carbon dioxide (CO2) and transported in pipelines. However, a trace amount of CO in the presence of oxygen (O2) and water can cause stress corrosion cracking (SCC) in carbon steel pipelines. This paper assesses the SCC risk of carbon steels induced by CO at different concentrations with or without O2 in lab simulated dense phase CO2 environments. Electrochemical measurements were also conducted to reveal the pseudo-passive behavior of carbon steels in different CO/O2/CO2 systems, and to help understand the resultant SCC behaviors.

Effective SCC Inspection Of In-Situ Oil Sands Pipelines Using Advanced Eddy Current Array Technology

Product Number: 51322-17981-SG

Author: Michael Sirois, Mathieu Bouchard

Publication Date: 2022

$20.00

ECA technologies are not very well known in the oil and gas industry and are still undeservedly suffering from the bad reputation of traditional eddy current testing from twenty years ago. Eddy current techniques are often humorously compared to "black magic" in the sense that the results are difficult to understand, the probes are complicated to use, and only eddy current gurus can use it efficiently. However, ECA has evolved significantly over the past 15 years and is now much easier and more intuitive to use.

The deposition of elemental sulfur is a major concern in the gas and oil industries. The effect of sulfur deposition on nickel-based alloy 825 under severe conditions is not well understood. This work investigates the impact of elemental sulfur deposition on Alloy 825 under two conditions using four-point bend test in accordance with NACE TM0316.The results show that alloy 825 samples were not affected by way of SSC, SCC, pitting or other corrosion damage mechanisms in temperature of 90° C, pressure of 75 bar, Chloride level of 1000 ppm, a partial pressure of H2S of 12 bara, and a partial pressure of CO2 of 55 bara with present of elemental sulfur. A further autoclave exposure test was performed in which alloy 825 samples were exposed in 20 bara H2S partial pressure and 57 bara CO2 partial pressure in 21,853 ppm chloride and =150gL-1 elemental sulfur at 190°C for 720 hours. Under this condition, alloy 825 shows environmentally assisted corrosion as well as SCC on all samples. As a conclusion, alloy 825 is not a robust material against elemental sulfur related degradation at high temperature and pressure with high H2S and CO2 environment. Hence, safety risk from elemental sulfur deposition at high temperature should be carefully considered and evaluated when using alloy 825. The limit tested in this paper could provide a reference for selecting alloy 825 in presence of sulfur.

Evaluation On Applicability Of Nickel-Base Alloy Weld Materials With High Chromium Content In BWR Environment

Product Number: ED22-17130-SG

Author: Takahiro Hayashi, Yoshinori Katayama, Daiki Tanaka, Yumiko Tsuchiya, and Hidenori Takahashi

Publication Date: 2022

$20.00

Ni-base alloy weld material has been widely used for primary reactor components of BWR. Stress corrosion cracking (SCC) in Ni-base alloy welds is of an increased importance and an ongoing subject in the industry to secure material reliability of the components especially for long-term operation of light water reactors. Although alloy 82 has shown excellent service performance in BWR applications, it is known that alloy 82 exhibit SCC susceptibility in laboratory tests under simulated BWR environment with a combination of particular, severe test conditions such as high level of material cold work and highly accelerated environment. In addition, few experiences with SCCs in the welds associated with alloy 82 have been recently reported in the operating BWR plants.
