Methods aimed at calculating wall thicknesses and testing strength of complex connectors designed for trunk gas pipelines
In this paper, authors consider the problem of determining wall thicknesses and checking the strength of steel pipe fittings of complex design such as bend-transition, oblique welded tee, welded tee from bent bends. Methods and algorithms for analytical determination of wall thicknesses of connecting parts have been developed. Analytical methods for calculating the connecting parts have been verified on the basis of a numerical analysis of the stress-strain state of the fittings of complex design using the finite element method for various combinations of the geometric parameters of the fittings and loading conditions.
