Abstract
In the article, based on a typical reduced model of the linear part of a steel main pipeline between four supports with a crack-like through defect, methods for numerical modeling of the main key parameters of the bandage in the form of circular composite linings are developed: the type of composite material, the length of the lining and the thickness of the lining. The presented calculation method is recommended to be used in the ANSYS software package. The results obtained can be used in modeling traditional and reinforced with composite linings main steel gas pipelines. Also, the described calculation method can be used for numerical studies of full-scale and reduced models of main steel gas pipelines, taking into account operational loads in the issue of increasing strength characteristics.
