EFFICIENCY OF PIPE FITTINGS USING FOR PIPELINE TRANSPORTATION SYSTEM ACCORDING TO THE TECHNOLOGICAL AND ECONOMIC CRITERION
Abstract
Modern transport energy systems are pipelines with structural elements intended to transport of energy carriers from their production sites to processing or consumption sites.
The basis of the transport pipeline system consists of a main pipeline that is a linear type construction which is a continuous pipe with an appropriate reinforcement which ensures the pumping of the transporting product at predetermined parameters (pressure, temperature, throughput, etc.).
The operational variability of the high-speed head of the energy carrier is a traditional issue of research and valuation. The function of the pipe fittings includes the implementation of dosing, control, sealing of the pipeline transport system. Therefore the problem of determining the regularities of the indicators formation of pipe fittings reliability in the transport pipeline systems design, production and operation of the technological heredity is relevant.
In the article it is analyzed the features of transport pipeline systems and the location of pipe fitting, it is substantiated theoretically the aspects of its reliability and cost reduction for maintenance and repair. It has been developed the general strategy of maintenance of operational reliability of pipe fitting of transport pipeline systems according to criteria of technological heredity. It is substantiated scientifically the forecast of the quality of management in auxiliary materials of technological purpose and it is developed the general principles of determination of the functional and technical condition in the transport pipeline system on the example of pipe fitting. In the article it is also shown that the suitability of transport pipeline systems degree is determined by the operational characteristics. It is identified the significant number of factors influencing on the reliability of pipeline fitting which are input, controlled and random which ensure the reliability and durability of nodes and components at the predetermined level during the exploitation. It is constructed the diagram of distribution of failures of pipe fitting depending on their design features, it is given the complex estimation of the efficiency of gas losses when the hydraulic state of the transport pipeline systems decreases.
It is calculated the dependencies which allow to estimate specific energy costs in the conditions of pipeline gas transport, power of the power drive, potential operation of gas flow after compressor stations, taking into account irreversible energy losses.
The nomogram has been developed which allows determining the above indicators with a high proportion of reliability graphically.
Keywords: pipe fittings, pipelines, efficiency, reliability, durability, factor, deformation, depletion.
