Experimental results and findings from a joint industry program entitled “Prediction and Assessment of Corrosion in Amine Solvents” conducted over the period from March 2003 to May 2007. An overview of experimental methods, observed results and trends, as well as comparison of predicted corrosion rates to refinery field data.
An advanced grade of super-austenitic stainless steel with a reduced content of nickel offers a significant economic advantage over nickel-base CRA’s. As the alloy is readily fabricated by conventional techniques, it is an excellent candidate for a variety of applications in the chemical, petrochemical, mining, oil and gas, and refining industries.
As CORROSION journal celebrates 75 years of corrosion mitigation and control research in 2019, we offer a selection of articles by decade. These articles remain the most viewed research articles of their respective decade, highlighting important topics, experimental methods and discussions surrounding the pertinent research of the day, and they continue to provide intelligence, perspective and insights for today’s corrosion research.
Tube coils in a radiant section of an ethylene cracking furnace are subject to corrosion. Repair welding of these tube coils is difficult. A degraded tube section is replaced by welding in a virgin tube section. The current paper presents the test results of a weld joint between a service-exposed tube and virgin tube using automatic orbital and manual gas-tungsten-arc welding (GTAW) processes.
Advances in precision, fully-digital ultrasonic wall-thickness measurement systems with cellular data back-haul enable accurate, deployable, and cost-effective corrosion monitoring systems. Comparisons are presented. This paper includes design principles of this next-generation platform, end-user input, and recent installation and operational experiences.
