Проблема изготовления труб по проектной информации

Abstract

The article considers the problem of increasing the efficiency of shipbuilding production on the basis 
 of pipe manufacturing technologies by design information. The reasons that prevent the manufacture of pipes by design information and possible ways to eliminate them are analyzed. Great attention to the manufacture of pipelines is explained by the significant amount of pipeline work, which makes 10-12% of the total labor intensity of building 
 a ship, and on some projects - up to 14-17%. At the same time, the share of pipes manufactured in advance does not exceed 40%. The solution of the problem is considered in a historical retrospective taking into account modern realities, because the development and improvement of the technology of pipe production is one of the main important directions in the development of shipbuilding not only in Russia, but also in the world. Significant changes in the technology are associated with the widespread use of computing devices to improve the computer-aided design, technological preparation of production and the manufacture of pipelines according to design information. There has been carried out comparative analysis of pipe production efficiency using pipe bending machines, bent segments and straight sections. To form the pipe configuration, it is proposed to retain the traditional technology of pipe bending using pipe bending machines. Directions for further research in this area are identified and solutions are proposed, the implementation of which will help reduce construction time, reduce labor intensity and increase the productivity of pipeline work when fulfilling shipbuilding orders. Ensuring the reliability of design information is aimed at increasing the proportion of pipes manufactured in advance, regardless of the functional purpose of pipelines.
