A Novel Methodology For Addressing Corrosion Under Insulation (CUI) Utilizing Corrosion Inhibitor Impregnated Self-Amalgamating Silicone Based Tape

Product Number: 51322-17931-SG

Author: Phillip Low

Publication Date: 2022

$20.00

Integrity management of corrosion under insulation (CUI) has historically and continues to be one of the biggest corrosion related challenges within the oil & gas, maritime, chemical and petrochemical industries.² Corrosion of piping, associated flanges, pressure vessels and structural components from CUI is a commonly found phenomenon and if left undetected or not stringently managed can result in catastrophic leaks or explosions, equipment failure and periods of prolonged downtime due to repair or replacement. It is estimated around 40% to 60% of an operator’s pipeline maintenance budget is a result of CUI.³

Gearbox Corrosion Mitigation During Storage and Intermittent Operation

Product Number: 51324-20747-SG

Author: Pavlo Solntsev; James Holden

Publication Date: 2024

$40.00

Gearboxes are one of the most critical pieces of equipment in a plant. Downtime because of gearbox failure can significantly impact manufacture and be very costly. An additional inventory of spare gearboxes is needed to minimize the effect of the loss. All gearboxes operating and during storage are susceptible to corrosion due to moisture condensation on the metal surfaces. The work describes oil additives that protect gearboxes during operation, layup, and warehouse storage. As was proved, the corrosion can be mitigated by adding a Vapor Corrosion Inhibitor (VCI) to the system. The testing methodology to verify the effectiveness of the oil additives, as well as compatibility with the base oil, was presented. Based on the present work, a specification for gearbox preservation during storage was developed.

Investigating Specimen Preparation and Cleaning Variables Influencing the NACE TM0208-2018 Jar Test Performance

Product Number: 51322-17985-SG

Author: Mitchell Fillbach, Mikel Roe, Daniel Neuburger, Barbara Nygaard, Mahin Shahlari

Publication Date: 2022

$20.00

The NACE TM0208-2018 Jar Test remains an industry-wide recognized standard for evaluating the vapor-inhibiting ability (VIA) of raw materials and finished products to provide off-contact corrosion protection of steel surfaces¹. It is particularly useful for comparing the efficacy of different VCI chemistries, as well as for monitoring performance consistency between productions of VCI functionalized materials.

NACE TM0208-2024, Laboratory Test to Evaluate the Vapor- Inhibiting Ability of Volatile Corrosion Inhibitor Materials for Temporary Protection of Ferrous Metal Surfaces

Product Number: NACE TM0208-2024

Publication Date: 2024

$109.00

Volatile corrosion inhibitor (VCI) materials provide temporary corrosion protection for the surfaces of metal parts that are not in contact with the inhibitor. Temporary protection is afforded as long as there is a moderately sealed enclosure containing the metal parts and the source of the VCI, which may be in the enclosing package itself. The duration of protection may be months to years before the parts are removed from the enclosure and put to use, or before a more “permanent” coating such as paint is applied. The referenced NACE Standard Practice SP0487 includes VCI in the context of guidance and best practices for users of interim or temporary corrosion protection methods.

Quantitative Test Method For Vapor Inhibiting Ability Of Volatile Corrosion Inhibitors

Product Number: 51322-17860-SG

Author: Khalil Abed, Mihad Ibrahim, Leitai Yang

Publication Date: 2022

$20.00

Metallic corrosion is a natural inevitable phenomenon defined commonly as the deterioration of metals due to reactions with their environments. The global cost of corrosion estimated by NACE in 2013 was found to be $2.5 trillion (USD), which is approximately 3.4% of the global gross domestic product (GDP). The two-year global study released at the CORROSION 2016 conference in Vancouver, B.C., Canada, assessed the economics of corrosion and the role of corrosion management in establishing best practices for the different industrial sectors. It found that implementing corrosion prevention best practices could result in global annual savings of 15-35 % of the cost of damage, which is equivalent to $375-875 billion (USD). These estimations excluded the cost of individual safety and environmental consequences from corrosion. Corrosion mitigation has been extensively researched. The methods of corrosion prevention include, but are not limited to, selection of the right material of construction, coatings, corrosion inhibitors, and cathodic protection.^1,2

Residual Analysis Assay For Thiol-Based VCI Quantification In Top-Of-Line Corrosion Environments

Product Number: 51322-17918-SG

Publication Date: 2022

Top of line corrosion (TLC) is a degradation mechanism predominantly encountered in the oil and gas industry. Initiation of TLC requires a stratified flow regime with wet gas transportation and the existence of a significant temperature gradient between the hot fluid inside the pipeline and the colder external environment.1,2,3 This temperature difference results in the condensation of water vapor, present in the gas phase, onto the cooler, upper internal section of the pipeline. The condensed water can be particularly aggressive as it lacks dissolved salts (e.g. bicarbonates), some of which are able to buffer the bulk electrolyte, increasing the pH and suppressing corrosivity.4,5,6 The absence of such salts typically results in a very low pH condensate (<pH 4), often containing dissolved acidic gases, such as carbon dioxide (CO2) and hydrogen sulfide (H2S), and also acetic acid (HAc), which can cause severe degradation, particularly in the form of localized corrosion.5

Study Of Inhibition Efficiency Of Volatile Corrosion Inhibitors In the Presence Of Heptane

Product Number: 51322-18003-SG

Author: Maryam Eslami, Marc Singer

Publication Date: 2022

$20.00

Top of the line corrosion (TLC) is a phenomenon encountered in the transportation of wet gas, where temperature differences between the pipelines and the surroundings lead to condensation of water and subsequent metal degradation. This kind of corrosion occurs due to the condensation of saturated vapors present in the unprocessed gas stream which collects on the internal surface of the cold pipe wall. The condensed liquid contains hydrocarbons and water. It forms a thin film and/or droplets of liquid on the pipeline. The condensed water phase can be, at least initially, very corrosive to typical pipeline (made of carbon steel), because it contains dissolved acid gases (such as carbon dioxide [CO₂] and hydrogen sulfide [H₂S]) and organic acids (such as acetic acid [CH₃COOH]).¹

Using the German Test Method TL 8135-002 for Multi-Metal Application: Non-Ferrous Alloys

Product Number: 51324-20795-SG

Author: Jonathan Brekan; Kristi Lanzo

Publication Date: 2024

$40.00

Volatile Corrosion Inhibitor (VCI) packaging has wide acceptance in the logistics world as an effective means for the protection of metal fabricated parts during shipping and storage. The utilization of VCI packaging for metals other than steel is still a challenge. Customers are reliant on packaging suppliers to provide them with a technical solution to their unique parts yet there are no standard test methods to prove that their offering is going to work for their alloy or part. This paper discusses the application of the well-understood, TL8135-002 Vapor Inhibiting Ability (VIA) test on a variety of non-steel specimens, including copper, brass, zinc, and aluminum.
