One of the most important directions of Russia's economic and energy strategy is to increase the efficiency in the field of heat supply. One of the options for solving this issue is using preinsulated pipelines, such as steel pipes in polyurethane foam polyethylene insulation. The experience of their application indicates several disadvantages associated with defects in pipes in polyurethane foam insulation and installed pipelines. The studies carried out made it possible to identify the main defects and inconsistencies in the manufacture and installation of preinsulated pipelines and the reasons for their occurrence. Following this, the authors have developed a set of operations and control tools during the installation of pipes in polyurethane foam PE insulation, clarifying the requirements of the input, operational and acceptance types of control, which contribute to improving the quality of the finished product, which was the purpose of this work.
