This document captures the key components required to get Thermal spray aluminum (TSA) coating installed by material engineering, project design and execution. These execution details apply to any TSA and insulation system installation whether it is a new construction project or in-plant maintenance project.
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.
The cathodic disbondment (CD) test is a well known and generally accepted laboratory test for pipeline coatings for a long time. What are we testing and what is the significance of the test? By means of basic investigations factors influencing cathodic delamination have been identified and their extent on the delamination radius has been assessed.
Initial investigations described at Corrosion 2011. This paper reports on development of a micelle detection instrument. Criteria for interpreting the presence of micelles will be reported and results of a simulated field study to investigate the link between inhibitor micelle presence and corrosion rate. Together with results from real field samples, this data will be presented as development of a new tool for field analysis of brines
