Analysis of approaches for creating pipe connections in oil and gas equipment

The article deals with the problem of connecting pipelines in the oil and gas industry. One of the connection methods is resistance welding. Often, the use of this approach shows muted efficiency as it depends on the qualifications of the welder. A technique for creating flange (plane) connections with a pipe in the oil and gas industry is considered. The necessary equipment and types of welds within the considered area are considered. Thus, it is necessary to conduct a literature-patent review to find an alternative method for creating welded joints in oil and gas pipelines in order to increase the reliability of such joints and reduce the cost of production. The analysis of the subject area and the search for possible solutions to the problem posed were carried out. Various welding methods (manual electric arc, automatic submerged-arc welding, induction brazing, etc.) are considered and a comparison of the main welding methods is given, as well as the rationale for the use of electron beam welding to create such pipe joints.
