In-Situ Observation Of Hydrogen-Induced Cracking Initiation Site In Linepipe Steels

Product Number: 51322-17816-SG

In the oil and gas industry, oil country tubular goods or line pipes are exposed to wet H2S environments (sour environments) in some cases. The presence of H2S in the sour environment enhances hydrogen entry into the steel due to the catalytic action of H2S. The absorbed hydrogen enhanced by H2S affects hydrogen embrittlement. Hydrogen-induced cracking (HIC) is a hydrogen embrittlement phenomenon observed in sour conditions.

Is 22 HRC the right threshold for TMCP large diameter pipes in severe sour environment?

Product Number: 51323-18943-SG

Author: Hervé Marchebois, Christophe Mendibide, Bruce Cowe, Carole Dessolin

Publication Date: 2023

$20.00

The manufacturing and field experience of high strength low alloy (HSLA) steel plates produced by Thermo-Mechanical Controlled Process (TMCP) are well defined in industry standards and literature. The TMCP method consists of a well-prescribed rolling pass schedule followed by accelerated cooling that leads to a fine-grain microstructure with the desired mechanical properties of the produced plates.
Quite recently, this TMCP process resulted in detrimental local variations with hidden hardness variations on pipe ID, so-called Local hard Zones (LHZ).

Line Pipe DC-ERW Long Seam Weld Anomaly Investigation

Product Number: 51324-21182-SG

Author: Luke Jain; Lee Vest; Rick Gonzales; Alex Hudgins; Ransom Stamps

Publication Date: 2024

$40.00

Linear anomalies were discovered during construction activities near to the DC-ERW long seam weld of a 20-inch natural gas pipeline. Magnetic particle testing and phased array ultrasonic testing were applied to characterize the anomalies. Pipe samples were removed from the pipe for additional destructive laboratory analysis. Laboratory analysis included visual assessment, X-ray computed tomography, cryo-fracture, cross-sectioning, metallographic analysis, and scanning electron microscopy. Inspection and testing results indicated that the anomalies were consistent with roller contact marks introduced during pipe manufacturing and did not show evidence of time-dependent growth. Representative anomalies were evaluated using a Failure Assessment Diagram to provide an additional level of assurance. All flaws were found to be acceptable in accordance with general application of API 579 Part 9, Level 2.

Long-Term Performance of HLP Solution for Mildly Sour HIC Testing

Product Number: 51317--9129-SG

ISBN: 9129 2017 CP

Author: Daisuke Mizuno

Publication Date: 2017

$20.00

Applicability of High Strength Line Pipe solution has been evaluated by conducting 30-day Hydrogen Induced Cracking (HIC) tests. Reproducibility of corrosion loss and HIC damage was investigated in comparison with those of the conventional solution, specified by NACE TM0284-2016, Solution C.
