The quality of indirect inspection data is critical in an External Corrosion Direct Assessment (ECDA). The need exists to increase the accuracy of the field data collection, to improve the data processing and to effectively present the results. This paper describes several challenges.

Impurity Reactions in Gaseous and Liquid CO2 Streams

Safe transportation of CO2 for carbon capture and storage requires strict control of contaminants in the captured CO2, so that corrosion and particulate matter problems are avoided. The present work tested two almost similar CO2 specifications for chemical reactions and liquid or solid drop-out. The tests were carried out with CO2 in liquid and gaseous state, at field-relevant pressure and temperatures. It was shown that the NO2 content had a strong effect on chemical reactions and tendency to drop-out, but the threshold was different depending on the physical state of the CO2. Presence of NO2 resulted in chemical reactions. Drop-outs were observed for 3 ppm-mol NO2 in the liquid state (+4°C, 100 bar) and for 8 ppm-mol in the gaseous state ( -3°C, 25 bar).

In Defense of the Monolithic Isolation Joint

Product Number: 51317--8993-SG

ISBN: 8993 2017 CP

Author: Monica, Michael

Publication Date: 2017

In Situ Atomic Force Microscopy Study Of Microstructure Dependent Inhibitor Adsorption Mechanism On Carbon Steel

Product Number: 51322-17739-SG

Publication Date: 2022

$20.00

Corrosion resistant alloys (CRAs) are used for many pipeline and wellhead components associated with oil and gas production environments but may be considered too costly for longer crude oil and natural gas production lines. Mitigation of internal corrosion for these types of pipelines is normally carried out by batch treatment or continuous injection of corrosion inhibitors, especially the surfactant type of organic inhibitors, which are more economical than using a CRA.

In situ Electrochemical Evaluation of Pitting Corrosion of Carbon Steel Pipelines Exposed to Slightly Sour Seawater Service

Product Number: 51317--9416-SG

ISBN: 9416 2017 CP

Author: Ray Case

Publication Date: 2017

$20.00

The study of pitting susceptibility of carbon steel exposed to slightly sour service environment is conducted by using direct current and electrochemical impedance (IES). The test matrix is designed considering the oxidizing potential of the seawater as the independent variable.

In Zinc We Trust? - Zinc-Free Anti-Corrosive Pigments

Product Number: 41215-906-SG

Author: Lars Kirmaier, Susanne Bender, Andreas Heyn

Publication Date: 2015

$20.00

Besides economic considerations, ecological and regulatory factors play an increasingly decisive role nowadays in the formulation of innovative coating systems. It is therefore no surprise that the call for zinc-free anti-corrosive pigments or those that do not require labeling has steadily increased in recent years. Zinc-free technology is not new. Numerous pigments based on calcium, strontium, aluminum, and magnesium phosphate have been available on the market for a long time.

Incorporating Monte Carlo Analysis into a State-of-the-Art Corrosion Prediction System

Product Number: 51323-18910-SG

Author: Andrew Simm, Daniel Thomas, Gareth John, Steve Hodges

Publication Date: 2023

$20.00

Over the years there have been several different corrosion modelling software packages developed to provide predicted (estimated) corrosion rates for use in the oil & gas industries. Many are based on the original work of DeWaard & Milliams which provided a best-fit statistical model to corrosion rates measured in flow loop laboratory tests conducted at the IFE (Institutt For Energiteknikk) in Norway ; covering (initially) just partial pressure of CO2, temperature, liquid flow velocity and pH (typically as bicarbonate and dissolved CO2).

Increased Productivity and Time Reduction Through Paperless Paint

Product Number: 51217-030-SG

Author: Ross Boyd

Publication Date: 2017

$20.00

Traditional paper documentation leads to several issues in both the field and home office. Paper documentation processes cause compliancy problems, poor data entry, and difficult communication between employees. Keeping data secure can also be problematic with paper reporting leading to inefficiency.

Increasing Weathering Test Acceleration Through higher Irradiance

Product Number: 41214-873-SG

Author: Allen F. Zienik

Publication Date: 2014

$20.00

While real time outdoor weathering exposures in benchmark climates, such as South Florida, are highly recommended for determining coating performance and service lifetimes, the lengthy test times required are often problematic. Therefore, outdoor and laboratory artificial accelerated weathering testing has become a mainstay in coatings testing, particularly in the product development phase.

Independent Research on the Effectiveness of Polyethylene Encasement as a Corrosion Control Coating for Ductile Iron Water and Wastewater Piping

Product Number: 51324-20943-SG

Author: Michael J. Szeliga

Publication Date: 2024

$40.00

Polyethylene encasement (PE) is a coating method that consists of a loose wrap of thin plastic around ductile iron piping (DIP), that is typically held in place with PVC tape. It has become the primary means of corrosion control on DIP water and wastewater piping even though no large scale independent studies have been performed to document how often the thin plastic is damaged. Damage to the PE exposes the DIP to direct soil contact and corrosion can occur. The frequency of these exposed anodic (corroding) areas on polyethylene encased DIP has also never been compared to the frequency of anodic areas on uncoated DIP. Uncoated DIP is DIP that that has the 2 to 3 mils thick factory applied black asphaltic paint applied to it. The asphaltic paint is water permeable and provides no significant reduction in corrosion activity on DIP. This research project evaluated cell-to-cell potential data on 89,275 feet of uncoated DIP and 51,609 feet of polyethylene encased DIP. Cell-to-cell potential measurements are the only way to accurately detect areas of corrosion on unbonded DIP.

Induction Heating Technique for Cold Weather Pre-Heating and Post-Curing or Liquid Epoxy Coatings on Gas Pipeline Girth Welds

Product Number: 51216-022-SG

Publication Date: 2016

During the winter of 2013-2014, Northern California experienced unusually cold temperatures (below 40°F). These low temperatures delayed Pacific Gas & Electric Company (PG&E) coating operations on new pipelines. Since liquid epoxy coatings capable of being applied at, or which fully cure at, temperatures below 50°F were not approved, PG&E chose to control the environment using small enclosures over the application area. This approach proved to be expensive and time consuming, so a novel method of pipeline surface temperature control was necessary to allow application of liquid epoxies at low ambient temperatures.
