Analysis of Тhermal-Нydraulic Сharacteristics of Сomposite Рipes Сompared to Мetallic and Рolymeric Мaterials

Abstract

A brief analysis of the thermal networks in the Russian Federation with evidence of upgrading necessity of the existing pipeline system is presented. A comparison of the various existing and promising materials of pipelines and thermal insulation from the point of view of their thermal-hydraulic characteristics are presented. It’s estimated an economic effect for the reduction of thermal and hydraulic losses in the comparison of composite and metal piping length of 1000 meters. It is shown that the optimum thickness of thermal insulation composite piping can be taken smaller than for the metal tube 4-5 mm.
