Investigation of the Performance of the Interval Radial-Stop In-Line Device Under Conditions of Increased Pressure

Abstract

The article reflects the results of a study to determine the operability of an interval radial-thrust in-line device, intended for use in the repair of the linear part of main gas pipelines. The paper contains information characterizing the stress-strain state of the most wear-out elements of the inline shell. The problem is reduced to finding the equivalent stresses for the initially selected material. The results of the study indicate that under the conditions of a one-sided force factor (pressure) of the gas pipeline medium, the limiting state of the material of the end element is not reached. As a methodological basis for the study, the use of finite element analysis is assumed. The result of the study is a picture of the distribution of equivalent stresses in the plane of the end element.
