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

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.

In-situ Performance of Galvanized and Zinc Rich Coating Systems for Structural Steel in a Chemical Plant Environment

Product Number: 41208-461-SG

Author: Chak Wong

Publication Date: 2008

Plant maintenance engineers continually search for new and improved ways of providing corrosion protection in their highly demanding environments. Structural steel is used throughout various applications including pipe racks, building components (beam and column configurations), reactor platforms, and signage, etc. Coatings systems have traditionally been the choice of providing corrosion protection for both steel and concrete substrate.

This study introduces the design and implementation of a bespoke electrochemical flow cell in combination with in-situ Synchrotron Radiation-X-Ray Diffraction measurements (SR-XRD). The system enables high precision, real-time, in-situ measurements of iron carbonate (FeCO3) evolution on carbon steel in a flowing environment, as well as providing real-time, in-situ corrosion rate measurement through an integrated three-electrode cell. The custom cell is used to examine FeCO3 formation kinetics in a carbon dioxide (CO2)-containing aqueous environment, particularly in instances where the ‘pseudo-passivation’ phenomenon is reported to occur. Linear polarization resistance and anodic polarization measurements were performed in combination with the SR-XRD measurements to establish a detailed understanding of FeCO3 formation in real time and its relation to the corrosion behavior of carbon steel. It was observed that ‘pseudo-passivation’ occurred in conjunction with the growth of a highly protective FeCO3 layer under all conditions evaluated. Magnetite (Fe3O4), an oxide layer often attributed to the onset of ‘pseudo-passivation’, was not observed in these conditions, despite the high limits of detection of the technique.

In-Situ Synthesis Of Corrosion Product-Polymer Composites On Carbon Steel For Enhanced Erosion-Corrosion Protection In CO2 Corrosion Environments

Hydrocarbons still remain as a fundamental contributor towards meeting the worldwide demand for energy, despite the growth of other alternative sources such as renewable and nuclear options. Due to low cost and availability, carbon steel, remains as the most commonly used material for pipelines in down and upstream activities within the oil and gas industry. However, carbon steel is not an exceptional metal alloy from the perspective of internal corrosion resistance. The economical cost for its degradation and related failures represent 10% to 30% of the maintenance budget in petroleum industry. It is therefore crucial that the corrosion of such a susceptible steel is managed and controlled accordingly.

Inspecting Hot-Dip Galvanized Steel

Product Number: 41216-960-SG

Author: Bernardo Duran

Publication Date: 2016

$20.00

Engineers, architects, DOTs, and other specifiers use hot dip galvanizing to provide corrosion protection to steel and iron in many industries, including transportation and highway, parking garages, bridges, structural, agricultural, petrochemical, and original equipment manufacturing. To ensure continued corrosion protection and structural integrity in these industries, it is necessary to properly inspect the galvanizing.

Inspection & Corrosion Control of Wet Sour Gas Subsea Pipelines

Product Number: MPWT19-15277

Author: Meshary A. Al-Bahli, Rashed Alhajri

Publication Date: 2019

Recently the oil, gas and petrochemical sectors have been facing together safety, environmental and mechanical integrity regulations as well as challenges associated with the need for cost reduction to improve competitiveness. Therefore, continual inspection and corrosion control health assessments and investigations are key towards sustaining reliability and availability together with value creation through avoiding unplanned production loss and asset failures. The present paper discusses an inspection and corrosion control technical assessment performed on thirteen (13) subsea flowlines. These flowlines supply wet sour gas feed from two offshore fields, gather through two 36 in” trunk lines. In order to meet the health and integrity objective, the assessment covers a review on the susceptibility and control of three (3) damage mechanisms using available literature covering field and empirical data. In addition, a review and discussion on the available and required inspection methods to combat the susceptible damage mechanisms are performed. This review is extended to an exploration and evaluation of (6) inline inspection techniques and two (2) remotely operated vehicles (ROV) to complement damage mechanism inspection methods.

During April 2010 through June 2010, tank repairs were performed at Defense Fuel Support Point (DFSP) in San Pedro, CA. A two-part Modified Epoxy Novolac Polysulfide Coating was applied to three (3) previously uncoated 50,000 barrel (Bbl) underground concrete storage tanks. The tanks have been in operation since 1942, storing various bunker and jet fuels. The scope included surface evaluation, surface preparation, concrete sealer application and coating application.
