Magnetic flux leakage (MFL) detection is frequently used for oil and gas pipeline inspection, especially evaluation of the integrity pipelines. The success MFL technique depends on many parameters. However, a sensitive magnetic sensor an important requirement. Therefore, field sensors based different mechanisms have been developed applied to technique. In this paper, we evidence first time capability innovative device planar Hall magnetoresistance devoted detection. This promising prototype...
This article presents the use of an electrically assisted manufacturing method in incremental sheet forming process to improve formability, surface quality, and geometric accuracy. system utilizes a direct current source connected directly metal through two electrodes at opposite edges conduct heat based on Joule’s effect. The approach produces homogeneous heating zone whole with very short ramping time. In this work, is designed serve investigation accuracy, roughness hot technology. Three...
Gas-liquid cylindrical cyclone (GLCC) separator is widely used in the petroleum industry with potential field applications. Its performance strongly influenced by inlet configuration. The 27° optimal inclined angle has been experimentally observed for GLCC same diameter of body and inlet. For other GLCCs, effect on flow pattern their performances have not investigated. main target current study to deeply understand changes respect different angles conditions. Twelve GLCCs were numerically...
We proposed a lightweight magnetizer toward the realization of portable circumferential magnetic flux leakage (MFL) inspection tool for detection longitudinal defects with linear motion between pipes and tool. The consists four permanent poles constructing configuration in which like are separated by θ angle ranging from 30° to 60° opposite supplemental θ. distribution field generated this caused was studied finite element methods as well experimental measurements. results reveal that new...
AbstractThe incremental sheet forming (ISF) technology has recently received considerable interest due to pre-eminence advantages for low-batch, high-quality, and customized products. Regarding the manufacturing of polymeric materials, this could be considered as potential candidate satisfy growing requirements low batch products in very short development production lead-times. In paper numerical simulation ISF process with a cone shape 45° wall angle, hemispherical-head tools helical...
This paper presents the design and simulation evaluation of a self-contained submersion robot that mimics actual flexible locomotion American knifefish. First, prototype bio-inspired with single undulating fin running along length is developed. segmental comprised sixteen rays produce sinusoidal waves to propel robot. Then, system modeling established investigate kinematics propulsion. A feedback linearization controller employed achieve propulsion velocity. The results demonstrate developed...
Abstract Gas-Liquid Cylindrical Cyclone Separator (short for GLCC) is a compact separator that has been widely used in petroleum production. The inlet configuration significant impact of the GLCC capacity separation. By utilization both FEM simulation and practical experiments, three configurations twelve inclined angles are investigated to find steadily operating industrial applications. In this study, flow pattern kinematic behaviour each thoroughly analysed. Besides, distribution velocity...
The remote-controlled explosive ordnance disposal machine, an important device used in the military, has been developed many countries. It become more intelligent and multi-functional due to being integrated with functional components. New generations have equipped a completely system high-resolution cameras. In bomb work, this machine can be replace other single-operating machines which allow reduce greatly consuming time labor effort as well safety for operators. There are significant...
Two Point Incremental Forming technology (TPIF) is one forming method of incremental sheet (ISF) which an innovation process with potential advantages such as simplicity, less-time consumption, and high flexibility. This using a hemispherical-end tool under CNC movement deforms metal fixed on simple frame. The clamped between movable plate clamp plate, the has support die bottom plate. lower firmly positioned machine table in while upper (included material, plate) able to move easily up down...
In this study, strontium is used as an alloying element for improving the pitting resistance of Mg-5Al-4Sn based alloys in alkaline solution. Potentiodynamic polarization measurements suggest that addition increases robustness a result higher potential and wider range passive potential. Electrochemical impedance spectroscopy (EIS) confirms formation solid film on alloy surface due to significant increase charge transfer resistance, well lower double layer constant phase magnitude values....
