51316-7333-Comparison of Corrosion Behavior in HIC Test Solutions for FFP evaluation

Product Number: 51316-7333-SG

ISBN: 7333 2016 CP

Author: Daisuke Mizuno

Publication Date: 2016

$20.00

Hydrogen Induced Cracking (HIC) can be a major issue for line pipe exposed to sour environments. In this study, influence of the test solutions on HIC evaluation was investigated from the view point of corrosion. Electrochemical measurements were employed to compare corrosion behavior of line pipe steels between the 0.93N acetate buffer solution and the conventional 0.05N acetate solution.

Alloying Effect Of Mo In Martensitic Stainless Steel On Passive Film In H2S-CO2 Environment

Product Number: 51322-17538-SG

Author: Kyohei Kanki, Katsuhiro Nishihara, Masayuki Sagara, Hisashi Amaya, Hideki Takabe

Publication Date: 2022

$20.00

Oil and gas wells are highly corrosive environments because they contain H₂S and CO₂. The 13Cr martensitic stainless steel is widely used in the oil and gas industry because of high good corrosion resistance in CO₂ gas wells. Generally, the addition of Mo increases the passivity of steel. However, the role of Mo in passive films has not been completely clarified.

Effect of Ni on Sulfide Stress Cracking and Stress Grooving in Carbon Steel - Part 1: Constant-load (Dead-weight) Test

Product Number: 51324-20715-SG

Author: Taishi Fujishiro; Taro Muraki; Nobuyuki Ishikawa; Daichi Izumi; Takuya Hara

Publication Date: 2024

Sulfide stress cracking (SSC) occurs in steel exposed to sour environments. Ni promotes the formation of a crack-like corrosion morphology (so-called stress groove or fissure), which accelerates the SSC; however, the mechanisms underlying fissure formation and growth are not fully understood. In this study, the effects of Ni on SSC and fissures were investigated. Constant-load tests were conducted at various potentials using TS 800 MPa grade steel with and without 1 % Ni addition. The fissures were formed near the corrosion potential on adding Ni. Anodic or cathodic polarization promoted SSC, suggesting that SSC was affected by both active path corrosion (APC) and hydrogen embrittlement (HE) mechanisms. In addition, the fissure shapes and crystal orientations of the microstructure were analyzed to classify the fissures as dissolution (corrosion) or mechanical cracking. Further, characteristic grooves promoted by Ni were confirmed to be APC.

Effect of Plastic Strain on Hydrogen Absorption of Low Alloy Carbon Steel for Linepipe

Product Number: 51323-19139-SG

Author: Taishi Fujishiro, Yusaku Tomio, Taro Muraki, Takuya Hara

Publication Date: 2023

$20.00

In the oil and gas industry, oil country tubular goods and linepipes are exposed to the wet H2S environment (sour environment) in some cases. The presence of H2S promotes hydrogen entry into steel due to the catalytic action of H2S. The absorbed hydrogen enhanced by H2S affects hydrogen embrittlement.

Full Ring Test in Sour Environment - Importance of Testing Set-Up and Strain Monitoring

Product Number: 51324-20997-SG

Publication Date: 2024

Full ring ovalization test is performed in line pipe to assess the susceptibility to sulfide stress cracking when the material is subjected to load and sour service conditions. A full ring test was performed under BS 8701 standard1 for a 36 inches welded line pipe, X65 material. The region of interest was monitored with strain gauges to control loading at the required stress level. After test completion, the NDT and visual inspection reported indications in some areas out of the region of interest. A detailed analysis was performed to find out the sources of indications. The study included material analysis and revision of sample preparation and test setup variables. For test preparation and setup analysis, 2D and 3D finite element work was performed to understand the effect of those variables on the cracking occurrence. The finite element analysis (FEA) results showed that geometry variations, loading control and testing setup have a considerable influence on the applied stresses. It was found that some zones out of the region of interest can be over stressed due to slight modifications in loading conditions. As a part of the analysis, a new test was performed with the corresponding adjustments observed in the numerical model, and strain gauges were located at the points where the FEA showed higher stress zones. The strain gauge readings confirmed the stress fields observed with FEA. Additionally, the second tested sample successfully passed the test.
