The work reported in this study focusing on the abrasive wear behavior for three types of pipes used oil industries (Carbone steel, Alloy steel and Stainless steel) using a apparatus dry wet tests, manufactured according to ASTM G65. Silica sand with hardness (1000-1100) HV was as material. these has been measured experimentally by measuring rate each case under different sliding speeds, applie...

Image monitoring of oil wear particles is currently only applicable to microflows and susceptible bubble interference. This paper develops an optical oil-monitoring system that can be used for large-diameter pipes with high flow rates. A shallow wide observation cell equivalent diameter Φ5 mm designed allow a theoretical maximum rate about 8 L/min, which significant improvement over current ima...

Exergy destruction in adiabatic pipeline flow of surfactant-stabilized oil-in-water emulsions is investigated in five different diameter pipes. The dispersed-phase (oil droplets) concentration of the emulsions is varied from 0% to 55.14% vol. The emulsions are Newtonian in that the viscosity is independent of the shear rate. For a given emulsion and pipe diameter, the exergy destruction rate pe...

One approach to solve the end to end (E2E) quality of services (QoS) problem of multimedia services delivery over multi-domain IP heterogeneous network infrastructures in a scaleable manner is the establishment of long term QoS enabled aggregated pipes. To allow dynamism, the actual service invocation of these pipes can be made as a separate action from the pipes subscription. This paper propos...

The results of a metallographic study of grey cast iron water pipes are reported. These pipes had been installed between 1885 and 1973 in eight different water systems. Each pipe had been extracted during scheduled maintenance or failure repairs to provide data for a larger study to produce a methodology for determining the residual life of grey cast iron pipes. This metallographic study was co...

The effects of groundwater flow and biodegradation on the long-distance migration of petroleum-derived benzene in oil-bearing sedimentary basins are evaluated. Using an idealized basin representation, a coupled groundwater flow and heat transfer model computes the hydraulic head, stream function, and temperature in the basin. A coupled mass transport model simulates water washing of benzene fro...

Corrosion effects on structural integrity and life of oil rig welded pipes are analysed by experimental, analytical, numerical methods. Experiments were performed using standard tensile specimens CT for static loading, Charpy impact 3 Point Bending fatigue crack growth with amplitude loading. In each case new old used to evaluate corrosion effects. Results indicated negligible in the properties...

Wireless sensors and measurement devices are widely deployed in oil and gas refineries to monitor the health of the pipes. These sensors are deployed along the pipes in an open area and thus are subject to large scale failures due to cyber-physical attacks and hazardous environments. In this paper, we study the resilience issues in collecting data from a dense and large scale set of sensors dep...
