Experiments in a large-scale flow loop provide an example of a somewhat increased corrosion rate under multiphase flow conditions caused by a low concentration of H2S in a CO2 saturated environment. Under operating conditions that prevent scale formation, the addition of 3ppm H2S in the gas phase increased the corrosion rate of AISI C 1018 and API 5L X-65 carbon steels, while the addition of H2...

Near-neutral pH and a low redox potential are considered favorable conditions for immobilizing radionuclides in deep repository systems within clay formations. Cigeo is the future French Industrial Center Geological Disposal high- intermediate-level long-lived radioactive waste, to be built at depth of 500 m Callovian–Oxfordian clay. In-depth knowledge mechanisms kinetics corrosion occurring on...

A large amount of oil and gas production needs to be followed by optimal pipeline maintenance. Most cases pipe leaks are sudden in nature that able cause losses over a long period time. The consisting sand particles increase erosion rate, especially at the elbows. Cases prevented through routine inspections based on accurate rate predictions. This study aims predict elbow piping systems using c...
