The polarity of the zinc-steel galvanic couple in hot aqueous solutions was published more than 20 years ago. It used an inorganic zinc primer coating that was applied under thermal insulation at elevated temperatures [30C-60C (86F-140F)]. Since the year 2000, industrial practices or standards do not recommend using inorganic zinc rich coatings under thermal insulation. Research has showed over the years that good practice of corrosion prevention under insulation is to apply an additional layer of a heat resistant modified epoxy or inorganic polymer coating as an additional barrier.
Although bridge construction extends back thousands of years, steel bridge painting is in its infancy. The first iron bridge was built in 1779, and the first steel was used in a bridge in 1828. Coated bridges from the 19th century survive, raising the question, “Can coatings protect steel bridges for the next hundred years?” The author discusses how to achieve 100 years of service life using current materials and offers recommendations for improving steel bridge painting.
Like most manufacturing representatives, representatives of the paints and coatings manufacturing industry know less about architects/specifiers than what architects/specifiers know about the paints and coatings manufacturing industry. The purpose of this presentation is to provide the paints and coatings manufacturing industry with (a) insight into the mysterious world of architects/specifiers; and (b) to explain what architects/specifiers expect of manufacturing representatives.
Now that you as a specialty coating / lining contractor have joined the fast-growing technology of polyurea elastomeric coating & lining systems, what’s the next step? The polyurea technology has grown in use by significant volumes since the initial start in the early 1990’s. Applications include concrete coatings / linings, steel coatings, traffic deck systems and specialty coatings.
The application of Corrosion Resistant Alloys (CRA) in harsh environments and severe services is gaining a leading position across the Industry. Among the different CRA Duplex & Superduplex stainless steels (DSS) represent an often-interesting choice in terms of cost-benefit ratio. Duplex and superduplex stainless steels as a matter of fact offer a competitive cost excellent corrosion resistance in many environments and good mechanical properties; they are often replacing and upgrading traditional stainless steels by closing the application gap with more noble alloys such as nickel and copper alloys. The quality control of DSS fabrications that involve welded joints cannot underestimate the possible influence of the welding process itself on the localized corrosion resistance of the material. Such alloys are characterized by a somewhat complex metallurgy which involves during welding the possible precipitation of undesirable phases & compounds that can induce an important loss of corrosion resistance in particular considering localized corrosion phenomena (e.g. pitting corrosion).During welding and materials qualification steps the most commonly specified test for checking localized corrosion resistance of CRA in particular in chloride-containing environments is the Ferric chloride ASTM G48 [1] corrosion test. So many End-User material & fabrication specifications have taken up this procedure by incorporating it and often customizing it. This is because the procedure described in the ASTM standard does not cover or define in detail many particular aspects of the test itself. This creates a number of free interpretations of the test procedure that can be associated with more or less severe test conditions and more or less easy-to-reach requirements. It can be useful to remember that the test itself is in any case not a real fitness for purpose test but more a quality control one; it is carried out under very severe conditions often more severe than the actual conditions in which components will be exposed. This also means that even small variations in the test procedure welding variables or welding metallurgy can tip the balance in the pass/fail equilibrium. The purpose of this work is to describe some fundamental aspects of test procedure and results evaluation somehow customizable with respect to the ASTM standard which may influence the test outcome itself also considering a possible review of the standard toward a more unified procedure. In this context taking into account that manufacturers find themselves in need to optimize the welding process with the aim to overcome G48 corrosion test during qualification the work also describes typical issues related to welding that could induce a negative verdict of ferric chloride pitting test.
This study is a result of analyzing the data and statistics from the Brooklyn Bridge project collected during lead paint removal operation. The $508 million Brooklyn Bridge Contract 6, which is still ongoing, commenced in 2010 as a part of New York City Department of Transportation’s (NYCDOT) $2.6 billion East River Bridges Capital Program.
This paper is a “high temperature” sequel to previous investigations of four specialty inorganic coatings said to prevent corrosion under wet insulation conditions with temperature cycling both in the CUI range of -5°C to 175°C and up to ca 400°C.
Corrosion under insulation (CUI) is a costly and complex problem for industry to contend with successfully. This paper describes a suite of accelerated laboratory tests undertaken in part to evaluate some of the claims made for engineered coatings touted to possess high heat resistance to 400°C and simultaneous anticorrosion properties.
The purpose of this article is to attempt to provide the reader a basic understanding of the minimum standard in providing a safe work environment for their employees and the general public when using open-air Abrasive Blasting equipment.
Oil and gas operations worldwide are impacted by the presence of microorganisms. A variety of microorganisms can be found in the oilfield, dependent on the type of operation, geology, location, water source and water treatment utilized. Biocides are used in all stages of oil and gas development to control microorganisms and their detrimental impacts on production such as corrosion, biofouling, and souring. A wide number of biocides are used to control microorganisms, ranging from oxidizing biocides that react quickly but leave no residual activity, to preservatives which act slowly, but provide antimicrobial activity for weeks or months at a time. The spectrum of biocides used in oil and gas are covered by several excellent reviews and will not be detailed in this paper.
