INFORMATION MODEL FOR FORECASTING OF TECHNICAL CONDITION AND DIAGNOSTICS OF PRODUCTS EXEMPLIFIED BY GAS INDUSTRY
Abstract
Products of the gas equipment and pipeline systems (GE and PS) and other gas power equipment operating in the pipeline transportation systems (PTS), is usually characterized by an initial technical condition. This is due to the specific design, materials used, quality of manufacture or repair as well as costs of transportation and storage. Substantial influence on the functional state of these products exerts the wear of highly-accurate micrometric pair of pipe fittings, which takes place in the process of their exploitation and results in the loss of the sealing property. It should be mentioned that this process of change in geometry of the interfacing surface of pipe fittings takes place gradually and in most cases these defects, which are actual failure, are revealed at maintenance service or operating repair of GE and PS products. Among other things, such situation can be explained by many reasons, for example, with a great amount of the products of GE and PS that are made or repaired on the proper type enterprises. However, in this case, requirements which are produced to any, both new and repaired articles must be corresponded to a normative and technical document, and also scientifically-based recommendations.Key words: gas equipment, pipe fitting, defect, failure, technological heredity, forecast.
