Selection of Priority Production Technology Based on Comparative Evaluation of the Oil and Gas Equipment Working Resource

The purpose of this article is to provide the largest working resource of oil and gas equipment by selecting a priority manufacturing technology. We propose to use the plasticity resource of the material as a criterion for the choice of technology. Manufacturing technology which provides the greatest plasticity resource of the material should be recognized as a priority. We propose a new procedure for comparing technologies using information on the plasticity resource of metal at the final stage of fabrication of the product. This procedure includes the following steps: (a) cutting samples from the regions of the structure with the most deformed metal, (b) determining the mechanical characteristics of the metal using the penetration method based on ESPI, (c) testing the samples for crack resistance, and (d) determining the plasticity reserve of the material. At the last stage, the concept of a two-stage process of damageability accumulation is used. The proposed procedure excludes a detailed analysis of individual technological operations. The use of this procedure will simplify the comparison of the different technological processes for the products manufactured and the selection of priority technology.
