Geothermal resources have been successfully used in the Netherlands for heating districts in agriculture. Due to the high chloride content and the presence of carbon dioxide in some of the geothermal fluids in combination with the intrinsic elevated temperatures these production environments represent a considerable challenge for the integrity of the technical equipment in the geothermal plant. Localized corrosion damage in downhole equipment reported by several operators confirmed the need for a corrosion strategy to mitigate the impact of the aggressiveness of the geothermal fluid under the current operational conditions. To address this a corrosion inhibitor was characterized in the laboratory using a rotating cage to simulate high temperature and high shear stress conditions. Based on the positive outcome of these tests the corrosion inhibitor was successfully implemented in the field. This paper documents the corrosion damage observed in downhole equipment before the use of corrosion inhibition the obtained laboratory test results as well as the experiences from monitoring the field performance of the corrosion inhibitor in this geothermal demanding application.

ADHESION TESTING How much is sufficient?

Product Number: 51218-161-SG

Author: Dr. Daniel Totev

Publication Date: 2018

$20.00

Pull-off adhesion testing of coatings is commonly used for product testing and qualification as well as quality control / quality assurance. However, initial adhesion values do not necessarily correlate with service life of coatings or their corrosion protection performance. Adhesion of several product chemistries to steel is examined in this study before and after immersion exposure. Results are presented within the context of laboratory corrosion testing in an effort to investigate the significance of adhesion testing in modern lining systems.

The Fukushima Daiichi Accident in 2011, which was the result of the Great East Japan Earthquake, tsunami, and prolonged station blackout, increased the focus on developing accident tolerant fuel cladding (ATFC), especially on the use of protective coatings. Coatings have been widely used in a variety of industries, including automotive, aerospace, and nuclear to improve corrosion resistance, enhance hardness and physical properties, and reduce wear. In an accident scenario, a coating may aid in reducing the oxidation kinetics and hydrogen evolution rates. The present study investigates the benefits that physical vapour deposited nitride-based coatings may have for ATFC.

Adhesion Failure Mode Analysis: Cyclic Peel Testing in Synthetic Sea Water

Product Number: 41209-482-SG

Author: Ray Holden

Publication Date: 2009

$20.00

In this paper, I will discuss such an example of when the predicted service of the coating determines that a more dynamic method must be utilized. I will discuss testing that was conducted for immersion service where flow of water over the surface was a major consideration. The question of how well the adhesion would hold up in real life service could not be properly answered by the degree of failure in this case. I discovered that the more important consideration was the survivability of the coating if a defect were introduced.

Adhesion Measurements of Coatings on Cylindrical Steel Pipes: Variability & Significance

Product Number: 41214-815-SG

Publication Date: 2014

Quality assurance of coatings on steel water pipes commonly relies on tensile pull-off measurements of the coating-steel adhesion, according to ASTM D4541. These tests are performed by adhering a metal ‘dolly’ to the coating with an adhesive, then scoring around the dolly circumference, through the coating down to the steel surface, before recording the stress necessary to pull the dolly (and coating) away from the steel pipe.

Adsorption Desorption Behavior of Water Soluble Film Persistent Corrosion Inhibitor

Product Number: 51319-12984-SG

Author: Sunder Ramachandran

Publication Date: 2019

$20.00

Water based corrosion inhibitors have been found that provide longer treatment lives and better protection than similar inhibitors in oil-based formulations. In this paper conventional film persistency tests are presented on a water soluble film persistent corrosion inhibitor. The conventional tests allow comparative evaluation of different corrosion inhibitors. Langmuir adsorption and desorption has been recently used to form a method of evaluating the impact of the loss of availability of a corrosion inhibitor. The adsorption-desorption analysis allowed quantitative assessment of loss of availability. In this paper these studies will be continued on a water soluble corrosion inhibitor that has been previously characterized as film persistent in conventional laboratory tests and field experience. The values of adsorption and desorption will be compared with values with a corrosion inhibitor that is not used in batch treatments. The work will aid quantitative laboratory assessment of film persistency.

Oil and gas transportation pipelines are often prone to internal corrosion in service environments. Two main strategies used to combat the problem of internal corrosion in pipelines involve the use of corrosion inhibitors (CIs) and more corrosion resistant alloys. Corrosion mitigation using inhibitors is a favorable choice because of better economic feasibility.

Advanced Ceramic Coating to Prevent Vanadate Ashes Corrosion in a Coke Calciner Heat Recuperator

Product Number: 51319-13327-SG

Author: Micael Presa

Publication Date: 2019

$20.00

Flue gas corrosion produces a severe attack over stainless steel tubes in coke calciner heat recuperators. This corrosion is produced due to the presence of sulphur and vanadium in the calcining process which forms low melting and volatile corrosion products together with the reaction between the metal and the atmospheric oxygen at elevated temperatures. In an attempt to avoid this corrosion advanced silica based coatings have been developed and applied over stainless steel samples and have been characterized and tested under laboratory conditions (microstructure adherence and abrasion resistance thermal resistance). Besides a specific corrosion test has been designed in order to check chemical resistance to sodium vanadate salts at high temperature. Due to the excellent behavior of the coating showing a complete protection of the samples several coated prototypes were prepared and installed in the hottest part of one coke calciner heat recuperator to certificate the protective performance of the coating under real conditions (TFumes= 700 °C; TSteel = 580 °C). After 4 years of validation tests 800 tubes of 310S stainless steel (6350 mm OD x 241mm WT and 5000mm lenght) were coated to build a whole coke calciner heat recuperator unit with an average coating thickness of 150 µm. In 2018 after 12 months in operation visual inspection reports that ceramic coating remains in place and none of the tubes has been corroded.KEY WORDSFuel ash corrosion stainless ceramic coating coke calciner
