AP Dynamics Inc. specializes in the fields of computational fluid dynamics (CFD), torsional vibrations, pipingx000D
stress, pulsation and erosion mitigation, and mechanical design. One of the current challenges is the erosion inx000D
Once Through Heat Recovery Steam Generators (OTSGs) piping due to water droplets existing in the flow ofx000D
steam. To mitigate the problem, a predictive approach is required to estimate the material loss in order to planx000D
preventive maintenance and maximize steam productions in oil extractions. Furthermore, the reduction ofx000D
erosion is needed to enhance longevity of steam pipes.x000D
The main goal of this project is the development of a model to predict the erosion rates in the steam pipes andx000D
propose a nanocoating based on using nanoparticulates for enhancing erosion resistance. To investigate thex000D
erosion rate caused by the steam jet within the pipes, AP Dynamics and the University of Calgary have formedx000D
a collaborative relationship to design, manufacture, optimize, and test a setup to mimic the steam jet systemx000D
with integrated sensors. In the proposed system, the unknown empirical parameters influencing the erosion ratex000D
of the internal surface of the pipes will be measured through dynamic analysis of the impacts on the internalx000D
surface of the pipes. To mitigate the erosion, the nanocoating will be applied to steel pipe sections. The steamx000D
erosion tested metallic substrates will be characterized via a various microscopy techniques.x000D
The developed system will be used for performing a comprehensive experimental investigation on the effectsx000D
of different steam jet velocities, droplet sizes, fluids, etc. on bare and coated steel pipes. The outcomes of thex000D
project will enable AP Dynamics to develop a model to predict and analyze the erosion in steam pipes andx000D
prevent catastrophic failures. The developed nano coatings can result in protective layers with higher erosionx000D
resistance values compared to the regular pipes. The outcomes of the research will enable training of HQP andx000D
provide a competitive edge for AP Dynamics for analyzing and preventing erosion failures in steam pipes.
