The article presents a feasibility study of the use of the izoproflex-115A pipeline based on thermal and hydraulic calculations of existing thermal networks in Saransk. When modeling two variants (pipe networks made of steel in polyurethane foam insulation and polymer pipelines "izoproflex-115") of pipelines, the same technique was used. Analysis of the calculation results of the longest section of the heat network showed that ISOPROFLEX pipes, on average, have a three-fold capacity reserve in relation to a steel pipe. The use of modern izoproflex-115A pipeline systems will ensure high-quality and uninterrupted heat supply to consumers, increase energy security and energy efficiency, reduce the accident rate of heat supply systems and improve the financial performance of heat supply organizations.
