Preventive Maintenance of Underground Pipeline with the help of Cathodic Protection
12V Battery, Electric Wire, Half Cell Device, G.I. Pipe, Multimeter
Ever increasing problems in oil or gas pipelines can have serve environmental and economic consequent. Therefore, large investments have been made in studies on corrosion prevention for buried pipes. Important research is being conduct to determine and predict the corrosiveness of the oil, corrosion mechanism in the ground and to develop effective protection techniques such as coatings for buried metallic structures. Moreover, because of the hidden character of pipelines and their low accessibility, installation, survey, maintenance and repairs is intricate, elaborate and expensive. Numerical modeling can provide some relief by simplifying and optimize installation, maintenance and repair. When used in the planning phase, conceptual mistakes can already be traced before any actual installation, by calculating different set-ups in cheap, harmless and fast simulations. Also, a model can provide reference values for measurements on operational sites that can help in the tracing and solving of any possible anomaly. Last but not least, the model technique creates a safe and cost effective on screen ‘virtual’ test environment where new corrosion engineers can gain experience without long and expensive ‘trial and error’ experiments on site.
