Method for reliability estimation of the main pipeline steelwork structure
Abstract: Factors affecting the reliability of steel pipelines are under consideration in the paper. A selection of probability models is presented and the random variables magnitude distribution is determined for internal pressure of the product transported and for the thermal gradient in the buried pipeline. The method for estimating the reliability of such structures is suggested, the comparative analysis for pipelines having different external diameters and for different internal pressure values of the product transported is presented. The problem of choosing the best level of pipelines safety is considered. The formulated and developed probabilistic method is distinctive in its analytical simplicity. The given method can be used at the design stage as well as during operation of transit pipeline: in the process of decision making of its major repairs, determination of safety power pressure under the practical engineering state.
Keywords: main pipeline, reliability of structures, loads and impacts random variables, probabilistic method.
