Abstract
This study presents results about stresses including thermal stress in internally heated subsea pipes that are subjected to laminar flow of crude oils. The hostile environment causes corrosion of carbon steel subsea pipeline in oil and gas applications. The suitability of high performing non-metal piping in subsea oil and gas applications is explored through ANSYS simulation. Three non-metals are used in this analysis, namely polyester, polyether ether ketone, and polyvinylidene fluoride. FSI analysis on these non-metal piping are studied to investigate the influence of the fluid and solid properties on the resulting thermal stresses in pipes. Different flow temperatures are used in laminar flow to study their influence on the resulting thermal stresses in pipe. Besides, the analysis model is validated through theoretical calculation on stresses of subsea pipeline.
