Cavitation Erosion Comparison Between Commercial Coatings and Polyurethane Coating Containting Nano-Carbon

Cavitation erosion occurring on the rudder, which is induced by cavities from a rotating propeller due to the local pressure decrease of the fluid, has adverse effect on the operation of the vessel. Cavitation resistant paints have been highly considered to prevent the rudder from eroding, because of its relatively easy application and low working cost compared to other preventing methods.

CFRP Reinforcement Anode For Cathodic Protection Of Steel Rebar

Only a few researchers have studied the effect of carbon fiber repair on corrosion processes. The main protective effect is the "protective barrier" which is sometimes called passive protection against corrosion, comparable to some techniques such as anticorrosion coatings of concrete structures. Indeed, CFRP materials, applied as external reinforcing material on reinforced concrete structures form a protective barrier against the penetration of moisture and pollutants such as chlorides or carbon dioxide.^1.2.3.4.5 Apart from this impermeable barrier action, it has been found in these studies that the confinement of CFRP concrete has a positive influence on the onset of corrosion and on its velocity. Very little research has investigated the coupling between mechanical reinforcement and impressed current system.^6,7,8

This case study involves an NPS 36, 107 km long pipeline (Pipeline A) installed in 2016. The subject pipeline is collocated with an NPS 30 pipeline constructed in 1999 (Pipeline B), for the entire route, and two additional pipelines near the start of its route (Pipelines C and D), all owned by the same operator.

Changes in Appearance and Corrosion Protection of Polyurethane Pipeline Coatings During Weathering Exposure

Product Number: 51217-038-SG

Author: S.G. Croll, C. Gu, V. Upadhyay, B.D. Keil,

Publication Date: 2017

Very thick polyurethane coatings are used to provide corrosion protection for water pipelines that must be placed below ground and then may be exposed to ground water. Occasionally there are construction delays and pipe sections remain above ground for extended periods before installation. Under these conditions, atmospheric conditions and exposure to solar UV light cause the coatings to lose gloss and become yellow. These changes can be very obvious and thus raise concerns that the corrosion protective qualities of the coating have also similarly diminished.

Changing The Landscape Of Thermal Insulation Coatings

Product Number: 51322-18201-SG

Author: Jeremy Daum, Neil Wilds

Publication Date: 2022

$20.00

Thermal insulation is a material that restricts the flow of heat. Heat spontaneously flows from a high temperature region to a low temperature region, and the greatest heat flow occurs through the path of least resistance. For this reason, thermal insulation is used as a barrier between two bodies at different temperatures either to reduce heat loss from the hotter body or to reduce heat entry into the cooler body.

Characterization And Further Development Of Austenitic Stainless Steel UNS S20910 Towards New Industrial Applications

Product Number: 51322-17648-SG

Author: Clara Herrera, Merlin Seifert, Helmuth Sarmiento Klapper, Julia Ditmann

Publication Date: 2022

$20.00

UNS S20910¹, also known as XM-19 by ASTM A276², is a nitrogen-strengthened austenitic stainless steel with high strength and excellent corrosion resistance. Besides nitrogen (N) it also contains higher amounts of chromium (Cr), nickel (Ni), manganese (Mn), and a similar molybdenum (Mo) content compared with UNS S31603, as well as small additions of niobium (Nb) and vanadium (V). High contents of Cr, Mo and N confer this stainless steel high localized corrosion resistance. Mo, Mn and Cr increase the nitrogen solubility in iron alloys.

Characterization Of The Surface Chemistry At Corroded And Non-Corroded Sites On Aluminum Alloy 7075-T6 Samples Exposed At Coastal Locations

Publication Date: 2022

Knowledge of the localized corrosion environment on a metal substrate can provide the critical link between atmospheric data and corrosion morphology and can enable the formation of a framework to predict service life as a function of environment. Over the last few decades the analytical characterization of bare metal surfaces undergoing atmospheric corrosion has improved, resulting in a more complete understanding and consideration of the environmental parameters involved. However, the corrosion processes and the role that the environmental parameters play in what is a multiphase system is rather complex involving chemical reactions and equilibria, ionic transport phenomena, and gaseous, aqueous and solid phases.

Chemical Agent Resistant Coating (CARC) System for Military Vehicles

Product Number: 41216-996-SG

Author: Alex G. Piazza

Publication Date: 2016

$20.00

The United States Army and Marine Corps (USMC) paint their vehicles with the Chemical Agent Resistant Coating (CARC) system. This system consists of a pretreatment, an epoxy primer, and polyurethane topcoat, similar to many other industrial paint systems, but with added functional requirements (e.g., chemical agent resistance, camouflage, and signature reduction) unique to these paints. The systems that utilize these coatings are also designed for specific capabilities, of which corrosion is usually a lower priority. Lastly, the vehicles and equipment of the Army and USMC typically operate in harsh environments, which are highly corrosive.

Organic corrosion inhibitors (CI) have widespread use in the crude oil refining industry for corrosion protection and mitigation.¹ An effective corrosion inhibitor is a chemical substance that is applied in low concentration into a stream which suppresses or mitigates a corrosion mechanism.^,2,3,4 Inhibitors can be classified into two classes: adsorption or film-forming with organic inhibitors falling under the adsorption class. In this type of inhibitor a self-assembled structure is formed, where an array of hydrocarbon tails extend away from the metal surface and the polar groups (e.g., N in amines) chemisorb onto the metal surface.² Over the years, certain classes of inhibitors have been established as industry standards to confront specific corrosion mechanisms encountered throughout the refinery process. Examples include, filming and neutralizing amines used in crude units to combat aqueous corrosion; polysulfides used in FCCU to combat hydrogen blistering, cracking and embrittlement; P-based chemistries to combat naphthenic acid corrosion.⁵

The crude oil produced by fracking or hydraulic fracturing method are high in sulfur content (0.5%)1. The vast majority of vessels that are used in the petrochemical industry to store and transport materials are constructed using Carbon steel. Coating linings used for corrosion protection inside of vessels and tanks must perform under severe conditions such as an exposure to corrosive gasses ( H₂S) and carbon dioxide as well as high temperatures, high pressures and often must withstand the cold wall effect and rapid decompression.

Different refiners have a variety of procedures in place for hydroprocessing reactor and reactor system shutdowns, depending on the scope of the work to be performed during the downtime. If activities are to be performed inside the reactor (e.g. inspection, maintenance, catalyst changeout, etc.) such that the reactor must be opened to air, shutdowns must include steps to address the various hazards. These same steps must also be applied to associated process equipment related to the reactor system susceptible to similar hazards and damage mechanisms.
