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...

The methodology for testing pipeline steels is suggested on the assumption that destruction of pipes in field oil pipelines by mechanism grooving corrosion simultaneous fulfillment such conditions as occurrence scratches lower generatrix pipe, eventually growing into a channel form groove, emulsion enrichment with oxygen, presence pipe wall metal stressed state, chlorine-ion oil-water required....

Grade 91 steel pipe was replaced after about 30 months of service. In this paper, the tensile properties, microhardness and chemical composition pipeline are systematically tested analyzed. The results show that properties still meet requirements relevant standards.

−− the aim of this work is the study of the problems that arise during roll coating application of paints on steel sheets. We put in evidence the particular effects due to the non-Newtonian properties of these fluids. At speeds above a certain critical value, the flow of paint through the applicator suffers a hydrodynamical instability called ribbing, which generates a patterned interface on th...
