The project of creating an expert company for the diagnosis of gas, and also oil and gas pipelines using MPS

Abstract

© International Research Publication House Various technological defects arise in manufacturing products and welded structures. Mechanical, chemical and thermal influences on structural materials during processing and welding procedures cause changes in ultimate strength, brittle fracture resistance, corrosion resistance, etc. The main operational causes of failures and damage are: defects; violation of operating conditions; corrosion; wear; the presence of overloads and unforeseen loads; improper maintenance, etc. The danger of the influence of defects on performance depends on their kinds, type and number. The classification of possible defects in the product allows us to choose the right method and means of control. However, it should be noted that the norms of rejection based on the results of non-destructive testing adopted in the guidance documentation do not guarantee that the presence of defects in an object with dimensions exceeding the permissible ones leads to a critical decrease in performance during operation. This is due to the fact that the applied X-ray inspection technologies do not allow us to reliably establish the type of defect and determine its characteristics, without which it is impossible to achieve an acceptable reliability of strength calculations. In this regard, this paper discusses the relevance of creating an expertise company for inspection of gas, and oil and gas pipelines using MPS (magnetic prospecting survey). The company will allow the owner of a pipeline monitoring with the use of the MPS method to obtain such data as: presence or absence of unauthorized tie-ins; location of pipeline defects. The main conclusions are made on the technical and economic analysis of the planned production, with the preparation of marketing, production and calendar plans; the risks of the project are analyzed.
