Analytic prognostic for petrochemical pipelines [PDF]
Journal of Mechanical Engineering Research Vol. 3(3), pp. 64-74,
2011, 2012 Pipelines tubes are part of vital mechanical systems largely used in petrochemical industries. They serve to transport natural gases or liquids. They are cylindrical tubes and are submitted to the risks of corrosion due to high PH concentrations of the transported liquids in addition to fatigue cracks due to the alternation of pressure-depression of ...

Effect of high temperature service on the complex through-wall microstructure of centrifugally cast HP40 reformer tube [PDF]
arXiv, 2020 Centrifugally cast reformer tubes are used in petrochemical plants for hydrogen production. Due to the conditions of hydrogen production, reformer tubes are exposed to high temperature which causes creep damage inside the microstructure. In this study, two different ex-service HP40 alloy reformer tubes which come from the same steam reformer unit have ...

Saturation Magnetization of Inorganic/polymer Nanocomposites Higher than That of Their Inorganic Magnetic Component [PDF]
arXiv, 2012 Herein, some magnetic nanoparticles (MNP)/clay/polymer nanocomposites have been prepared, whose saturation magnetization is higher than that of pure oleic acid coated MNP component. The existence of unique 'nano-network' structure and tight three-phase nano-interface in the nanocomposites contribute to the surprising saturation magnetization.

Origin of the Significant Impact of Ta on the Creep Resistance of FeCrNi Alloys [PDF]
148th Annual Meeting & Exhibition of The Minerals, Metals &
Materials Society, TMS (The Minerals, Metals & Materials Society), Mar 2019,
San Antonio, United States. pp.1057-1066, 2020 Heat resistant FeCrNi alloys are widely used in the petrochemical industry because they exhibit a unique combination of creep and oxidation resistance at temperatures exceeding 900$^\circ$C. Their creep properties are often optimized by micro-additions of carbide forming elements.
