Abstract

In the modern petroleum industry it is vital to provide reliability and proper operation of transmitting pipelines, which are often subjected to various defects including volumetric surface defects (VSDs) arisen as a result of corrosion or erosion. In this, we consider a problem of computer simulation of pipeline fragment subjected to two VSDs and repaired by setting a composite wrap of a special structure. The algorithm of automatic finite-element model building based on the initial problem parameters is developed. The computational experiments on the influence of different parameters of the problem on a stress strain state of the pipe are conducted and discussed.
