A Simple and Efficient Method for Obtaining the Whole-Range Uniaxial Tensile Properties of Pipeline Steel

Metals, 2018
To obtain the whole-range true stress-true strain curves of API X65, a method is proposed based on the equal proportion principle and digital images. The tensile elongation was obtained by tracing the gauge points on the specimen surface, and the true ...

Synergistic Corrosion Inhibition of API 5L X65 Steel by Phytochemical Extracts: A Multitechnique Approach With Computational Validation

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The synergistic corrosion inhibition of nine phytochemicals from Azadirachta indica (neem) and Dypsis lutescens (golden palm) on API 5L X65 steel in acidic media was studied using DFT, MC, weight loss, EIS, and Tafel (PDP) methods, supported by FE‐SEM and EDX analyses.

Microbiologically influenced corrosion in aluminium alloys and premier techniques for comprehensive identification and characterization across diverse metal types

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 6, Page 1143-1158, June 2025.
Abstract Microbiologically influenced corrosion (MIC) is acknowledged as a significant type of corrosion due to its extensive impact on metal/alloy surfaces. As MIC accounts for 20% of all corrosion instances, it is a critical factor causing service failure of engineering materials such as steel and aluminium alloy.

Classification of pitting corrosion damage in process facilities using supervised machine learning

The Canadian Journal of Chemical Engineering, Volume 103, Issue 1, Page 153-169, January 2025.
Abstract Corrosion is widely known to be a major cause of the failures in process facilities. Prediction of corrosion damage is therefore essential for industries to manage the availability of their assets. This research aims to investigate the application of supervised machine learning methods for the classification of pitting corrosion damage ...

Materials testing and characterization of four X60-X65 pipeline steels

, 2021
This report summarizes the main results from the slow strain rate tensile testing campaign performed within the framework of the HyLINE project. The base metals and weld simulated heat affected zones of four pipeline steels, in four different positions of the pipes, have been tested under in-situ electrochemically charged hydrogen conditions and in air

Carbon Dioxide Corrosion Mechanisms: Historical Development and Key Parameters of CO2‐H2O Systems

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
The recent failures in flexible pipes have motivated the exhaustive research of corrosion mechanisms on high‐strength carbon steel armor wires that are the main structural compounds of those structures that mostly operate in seawater environments in the presence of carbon dioxide (CO2) and confined spaces.
