Variants of pipeline assemblies made of composite materials and their connections and technological units
The object of research is a polymer composite pipeline with connections and technological nodes. Method. During the research, methods of system analysis, methods of expert assessments, risk theory, comparative method, method of generalization, abstraction, induction, and deduction were used. Results. The analysis of theoretical sources, tests, scientific publications and regulatory documents was carried out, as a result of which the criteria for the characteristics of polymer composite networks were established, providing conditions for the economically and practically profitable use of polymer composite networks based on the project of a high-rise construction object, as a result of which the criteria for the characteristics of the object were established, providing conditions for the economically profitable use of self-lifting formwork, and a financial and economic model to justify the investment in this project has been invested. The pipes can operate at an operating pressure from a vacuum of 0.01-0.35 MPa and at an operating temperature from -269 to +150°C. The polymer composite material must contain a binder in the range of 28-36%, and the density of the binder varies from 1.75 to 1.85 g/cm3.
