Description

technical field [0001] The invention relates to the technical field of pipeline network monitoring, in particular to a system and method for evaluating the performance of a fluid dynamic system. Background technique [0002] Oil and gas pipeline networks can be susceptible to corrosion over time. For example, acidic and mineral-laden crude oils are highly corrosive to metals. In extreme cases, pipe sections can corrode to the point of leakage. Because such leaks can prevent the efficient operation of the piping network, corrosion in pipelines is often monitored. Corrosion sensors and / or monitors are used in the detection and monitoring of loss of materials (eg, inner surfaces of pipeline walls, etc.) due to corrosion and / or erosion from interactions between the material and the environment in contact with the material. Some types of corrosion monitors use the electrical resistance method to detect the loss of material thickness in the pipe wall due to corrosion. Other ty...

[0003] However, there are no criteria for selecting individual monitoring sites along the pipeline network. For hand-held monitors, corrosion is monitored at locations selected by the operator of the installation. Typically, these locations are determined intuitively by the operator. Some types of Resistive corrosion monitors are permanently mounted to individual locations on the pipeline, with regard to hand-held devices, no guidance exists for determining optimal placement of such monitors
