Nanocomposite pipelines energy efficiency

Abstract

Today multilayer metal-plastic pipes manufactured by means of special technologies are becoming widely applied. The main advantages of the so-called nanocomposite pipes are the increased service life (up to 80–100 years) and high corrosion resistance. The paper considers energy aspect of application of nanocomposite pipes in utility systems. It was shown that due to the low roughness, even at the initial stage of operation, electric power consumption for driving pumps in nanocomposite systems is almost 1,5 times lower respect to steel pipelines. In the long term, due to the buildup of deposits in steel pipelines, the effect increases by an average of 8% for each subsequent year of operation.
