Determining When to Coating Concrete

Product Number: 51220-268-SG

Author: Manuel Najar

Publication Date: 2020

Reinforced concrete is the most common building material in water and wastewater treatment facilities. It is very common to see unprotected concrete in severely corrosive environments or corroding reinforcing steel that has been exposed due to construction defects or coating failures. The decision to coat new and existing concrete structures can be very difficult for owners due to the cost, turn-around times for putting structures back into service, and lack of confidence in certain protective coatings.

Develop Test and Validate a Corrosion Monitoring Cell to Quickly Evaluate Effectiveness of the Corrosion Control Measures

Product Number: 51319-12841-SG

Aboveground storage tanks (ASTs) are widely used in the oil and gas and nuclear industries. These are typically constructed of carbon steel bottoms and shells with the bottoms susceptible to corrosion. Corrosion control measures include cathodic protection (CP) systems various levels of vapor corrosion inhibitors (VCIs) and combinations of VCIs CP and possibly biocides. The objective of this project was to develop test and validate an ultrasonic testing (UT) resonance probe and a corrosion monitoring cell to quickly evaluate the effectiveness of corrosion control measures with a focus on measures that involve CP alone and a combined application of CP and VCIs. The UT probe is an electromagnetic acoustic transducer (EMAT) used to generate ultrasonic shear waves for a resonance-based measurement approach. Three tests with the UT probe attached to the back of the carbon steel coupon set on wet sand were conducted in parallel. Test 1 started at open circuit (i.e. no CP) without any corrosion control measures followed by −850 mVCSE CP application later. Test 2 started with −850 mVCSE CP application followed by an open circuit. Test 3 started with both −850 mVCSE CP and VCI application followed by an open circuit. The posttest coupons were cleaned and scanned by a laser profilometer for corrosion depth measurement which was compared to the UT probe data.The resonance sensors successfully detected the onset and progress of corrosion from Cells 1 and 2 as CP was enabled and disabled. The absence of corrosion in Cell 3 also was clearly detected. The fundamental accuracy of the sensors was shown to be on the order of 1–3 µm when the surface being measured is very uniform. However it was not possible to make a quantifiable correlation between the corrosion profiles and the estimates from the sensors. When located over a non-uniform surface the sensors underestimated the amount of thickness loss likely due to scattering effects from feature scale lengths as small as or smaller than the ultrasonic wavelengths used as well as the variation in corrosion depths. Potential research is needed to understand the effects of variations in the surface that are small compared to the ultrasonic beam and even the ultrasonic wavelength. The adhered corrosion product on the coupons also may have affected the thickness readings because some of the ultrasonic beams were likely reflected from the corrosion/air interface in addition to the metal/corrosion interface. Further investigation would be required to determine if this was a significant factor.

Developing Additively Manufactured Alloy UNS N07718 for Critical Oilfield Applications

Product Number: 51323-19220-SG

Author: Wei Chen, Thomas Dobrowolski, Paul Agosta, Nicholas Barta, Lakshmi Vendra, Juan Carlos Flores

Publication Date: 2023

$20.00

Additively Manufactured Alloy UNS N07718 (AM 718) has been increasingly adopted for components in oilfield applications. AM 718 fabricated using laser powder bed fusion (LPBF) has demonstrated not only excellent mechanical performance, but also promising capabilities in critical services such as sour or hydrogen-generating conditions. In oilfield applications, it is generally felt that AM 718 should comply with API standard 20S4, and align with the requirements for wrought 718 in API 6ACRA.

Additive manufacturing (AM) is a transformative technology that has opened areas of design space that were previously inaccessible by enabling the production of complex, three-dimensional parts and intricate geometries that were impractical to produce via traditional manufacturing methods. However, the extreme thermo-mechanical conditions in the AM build process (e.g., cooling rates ranging from 103 K/s
to 106 K/s and repeated heating/cooling cycles) generate deleterious microstructures with high residual stresses, and extreme compositional gradients.

Developing Vapor Phase Corrosion Inhibitors for Aluminum Alloys in Ethylene Glycol Coolant Solutions

Product Number: 51324-20382-SG

Author: Behzad Bavarian; Lisa Reiner

Publication Date: 2024

Different vapor phase corrosion inhibitors were evaluated to determine their corrosion inhibition for aluminum alloys in Ethylene glycol (C2H6O2) coolant mixture. When the temperature exceeds 80°C, ethylene glycol can decompose into organic acids. The resulting acidic environments cause severe localized corrosion of aluminum alloys. The corrosion behavior was studied at multiple temperatures in different corrosion inhibitors using different concentrations. Corrosion inhibitor VCI-A, VCI-B, VCI-C, and VCI-D at 2.5-3.0% dosage showed excellent corrosion protection. VCI-A, VCI-C and VCI-D maintained a steady, low corrosion rate during long term exposure by neutralizing pH and forming a hydrophobic film. They increase the polarization resistance by a significant factor, therefore, lowered corrosion rate. VCI-B inhibitor, also showed the ability to reduce the corrosion rate of aluminum in ethylene glycol solutions. However, due to its high pH chemistry, the effective dosage should be maintained at <2.5% to avoid any potential increase in pH that can promote localized corrosion or under-deposit corrosion attacks of aluminum alloys. The results of this investigation demonstrated that these inhibitors can lower the corrosion rate in water-ethylene glycol solutions by neutralizing pH and forming stable films.

Author: Haoran Wang, Qixin Zhou

Publication Date: 2018

Self-healing coatings have been promising due to their automatic recovering functions, which can extend the coating lifetime with lower maintenance costs. One of the most effective strategies to achieve self-healing property is to encapsulate healing agents inside microcapsules and integrate the microcapsules into the coating matrix.
