What’s Wrong With ASTM G48 Qualification Test in Duplex SS Welds?

Product Number: 51319-13118-SG

Author: Marco De Marco

Publication Date: 2019

$20.00

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.

When Undercover Agents Can’t Stand the Heat” The CIA and the Nether World of Corrosion Under Insulation (CUI)

Product Number: 41212-694-SG

Author: Mike O’Donoghue, Vijay Datta, Adrian Andrews, Sean Adlem , Matthew Giardina,Nicole de Varennes, Bill Johnson

Publication Date: 2012

$20.00

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.

Why Are Glutaraldehyde/Quaternary Ammonium Biocides So Common In The Oil And Gas Industry?

Product Number: 51322-17640-SG

Author: Ethan Solomon, Jon Raymond, Makensie Moore, Nigel Watson, Anup Rama, Nora Eibergen, Ken Wunch

Publication Date: 2022

$20.00

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.

Why Do We Record the Attributes of a Coating Failure as a Result of an Adhesion Test?

Product Number: 51220-229-SG

Author: David J Barnes

Publication Date: 2020

$20.00

International standards, both ISO and ASTM, require that the attributes exhibited during an adhesion test are recorded as part of the results. What are these attributes, how should they be recorded and what value are they to the inspector and applicator in assessing the reason for failure? This paper looks at all these questions and asks should we be going further than we do in defining the mode of failure.

$20.00

In our world of protective coatings, water usually seems to cause trouble. In relation to coating concrete - determining how wet the manhole structure is paramount in our struggle to rehabilitate these manholes. And we are not talking about the manholes used to contain water during heavy rains or floods, strictly the sanitary manholes. A few ASTM test methods are important tools.

Why Voltage Matters For High Voltage Holiday Testing On Steel

Product Number: 51322-17662-SG

Author: Cameron Walker, Vaughn O’Dea, Joshua Bell, Javier Tormes

Publication Date: 2022

$20.00

A holiday is defined as a pinhole or discontinuity in a coating lining. These discontinuities are frequently very small and not readily visible and create a pathway for oxygen and an electrolyte to cause deterioration of the underlying substrate. These defects will tend to reduce the life expectancy of a coating in service, particularly if the service is to include immersion, such as the lining of a tank or a pipe.
