A modelling effort was made to try to predict the life of downhole tubes or casings, synthetically considering the effect of service influencing factors on corrosion rate. Based on the discussed corrosion mechanism and corrosion processes of downhole tubes, a mathematic model was established. For downhole tubes, the influencing factors are environmental parameters and stress, which vary with se...

The paper treats the application of various non-destructive testing methods to preventive examinations of vital elements of thermo-energy systems operating at elevated temperatures and pressures. The elevated pressures and temperatures produce thermal stresses in the material of a device, i.e. a system, which may result in material creep. On the occasion of a preventive inspection of a steam li...

Abstract We performed tomographic investigation of the most heavily perturbed (thus highly radioactive) rod and its pristine/unirradiated replicate from target No. 12 Swiss neutron spallation source (SINQ). The dataset reveals 3D re-distribution lead filling inside irradiated Zircaloy tube. change in linear attenuation coefficient both tube (due to presence entrapped products) comparison with m...

nowadays, tube bonding in vehicles structure is noticeably considered by many researches. in this paper, local tube compression process by a rubber ring has been studied. firstly, simulation of the process was performed by fem. then, experimental test has been carried out to validate the numerical results. numerical and experimental results were compared showing a good agreement. in the second ...

Traditional fossil fuels lead to environmental problems and are also depleting. A significant portion of global energy consumption is due to building’s air conditioning. Nowadays there is a great attention toward renewable and sustainable energy sources to support the buildings energy requirements. In this study, a solar cooling machine was designed for a three-floor residential building under ...
