Materials properties that are used in specific oil and gas environments are de-rated due to the risks associated with hydrogen embrittlement cracking. In oil production environments the concern is for the onset of stress corrosion cracking (SCC), while in seawater environments the concern is for Hydrogen Induced Stress Cracking (HISC). Both are hydrogen embrittlement phenomena with the distinction being the source of hydrogen for each. In SSC the source of hydrogen is from the presence of H2S in the oil production fluids, and in HISC the source of hydrogen is from the dissociation of water from the cathodic protection system. This paper is focused on the latter phenomena and aims to characterize the susceptibility of carbon alloy steels as applied in fastener applications, in a seawater environment under cathodic protection.

Recently, Countries around the world are taking steps to reduce carbon, which is considered a major cause of environmental pollution and the hydrogen market, an eco-friendly energy, is growing rapidly. Major countries such as the United States, Japan and the European Union (EU) are strengthening policies for the use of hydrogen energy and hydrogen-related projects in various fields, from materials to chemistry, energy and mobility, are being actively carried out. In order to use hydrogen energy, it is the most efficient and currently the most reasonable method to transport the produced hydrogen as high-pressure gas through a pipeline.

The T-8-20 Task Group conducted a survey of plant practices and of the performance of materials of constrution in HF Alkylation Units. A Primary goal of the survey was to expand the limited body of the information on alternative ally performance in HF Alkylation units and to better define the susceptibility of steel to hydrogen induced cracking.

Precipitation hardened (PH) nickel alloys have been broadly used in various applications in the oil and gas industry thanks to its high strengths and outstanding corrosion resistance in several aggressive environments. Alloy 718 (UNS1 N07718), Alloy 925 (UNS N09925), Alloy K-500 (UNS N05500), Alloy 725 (UNS N07725), and others are among the most used PH nickel alloys in the oil and gas industry. Despite of their known high corrosion properties, hydrogen embrittlement is one common failure reported by the industry for this class of alloys.

This study introduces a modulated Impressed Current Cathodic Protection (ICCP) system, specifically designed for Oil & Gas subsea production structures. Unlike traditional Sacrificial Anode Cathodic Protection (SACP) systems, which provide a constant output, the prototype operates on a closed-loop feedback system to dynamically control cathodic potentials within a specified voltage range. This allows for adjustments to varying environmental conditions, such as seawater temperature and microbial activity. The paper outlines the design, development, and testing of this innovative ICCP system and offers a comparative evaluation with existing SACP methods. In doing so, it addresses some of the limitations of current SACP systems, including issues like hydrogen embrittlement and premature anode depletion. The goal is to demonstrate the enhanced effectiveness and sustainability of the proposed ICCP system in subsea corrosion protection. Future work aims to integrate a patented predictive modeling feedback mechanism to further optimize the system's adaptability.

Attempts for Preventing Hydrogen Embrittlement and Solving the Infrastructure Problems for Hydrogen Gas Transmission Lines - A Practical IGC Study Based on Surface Thermodynamics

Product Number: 51324-20697-SG

Publication Date: 2024

This work summarizes the preliminary results of an effective experimental methodology called IGC, Inverse Gas Chromatography. IGC analysis is a well-established, surface thermodynamics technique. Different types of model coating materials have been tested under relatively identical conditions to determine their ability to interact with hydrogen gas. Findings helped establish a practical way of ranking materials with respect to their interaction with hydrogen. This potentially leads to their ability to protect the infrastructure by either reducing the chances for hydrogen to reach or eliminating it from reaching the metal surface entirely. Greater protection is expected to be achieved with the use of coatings that very weakly interact with hydrogen gas as opposed to those that interact strongly and allow the hydrogen to diffuse into them.

This paper presents the output from a study with the aim to correlate hydrogen gas charging and electrochemical charging for a X65 pipeline steel. The hydrogen uptake and diffusivity were evaluated via the permeation technique by employing both hydrogen gas charging and electrochemical charging. The effective diffusion coefficient, Deff, was determined by partial transients. The sub-surface hydrogen concentration, C0R, was then employed to determine the equivalent hydrogen pressure, pH2eq, of electrochemical charging conditions. In parallel, a permeation cell consisting of two membranes with thickness 6 mm welded together with a narrow gap in between was built. This unit was exposed to equal cathodic polarization conditions as the electrochemical permeation cell. The equilibrium pressure in the gap was measured and compared to the calculated hydrogen pressure from the gas permeation test with good correlation. Finally, an initial evaluation through toughness tests with the same X65 material executed in i) hydrogen gas and ii) electrolytic charging at equivalent hydrogen concentrations, gave promising results concerning the correctness of the correlation between the two hydrogen sources.
