Modeling a composite assembly for repair of trunk pipelines

Abstract

Abstract The article considers the issue of the efficiency of the use of composite materials in the repair of trunk pipelines. During the study, simulation experiments were carried out using the Solidworks program for the main product pipeline under excess pressure P = 4 MPa. Altogether, eight situations were studied that differed in the amount of composite material applied to the defect. The criterion for determining the number of situations was determined by the number of layers of the composite material at which a favorable situation for the operation of the pipeline occurs. As a result of the experiments, the dependence of the stress-deformed state on the number of layers of the composite material deposited at the defect site is obtained. This dependence allows us to recommend a certain composition of the composite unit for repair of trunk pipelines. The research results obtained have the prospect of their further application in the development of a standard program for the repair of trunk pipelines using composite materials.
