This work studies a series of factors influencing erosion-corrosion in oilfield gathering pipelines steel using the home-made testing pipe flow loop. Results showed that was corroded oil-water flow. The corrosion rate increased with velocity on whole, and addition solid particles would intensify localized corrosion. For test added 2 wt% quartz sand at m/s, portion pure erosion accounted for 47....

Chitosan–copper oxide (CHT–CuO) nanocomposite was made by an in-situ method utilizing olive leaf extract (OLE) as reductant. The OLE mediated CHT–CuO containing varying amount of chitosan (0.5, 1.0 and 2.0 g) evaluated corrosion inhibitor for X60 carbon steel in 5 wt% hydrochloric acid solution. inhibitive performance assessed weight loss electrochemical impedance spectroscopy, linear polarizat...

this paper presents a k- turbulence model for simulation of steady current and itsinduced vortex shedding caused by the presence of an offshore pipeline. performance of the modelaround a circular cylinder above a wall with gap to diameter ratios of 0.1, 0.35 and 0.5 underdifferent flow regimes with reynolds numbers of 1500, 2500 and 7000 is studied. the flow field iscomputed with solving the re...

To ensure the reliable functioning of main pipeline for water transport in hydropower, which has been operational 50 years, a detailed analysis pipeline’s material condition is necessary. The undergoes changing exploitation and working conditions, including extreme load phases such as periodic intensive emptying filling with inspection. In this paper, we analyse resistance NIOVAL47 steel using ...
