ABOUT RATIONING RELIABILITY PIPES AND PIPELINES

Abstract

The choice of reliability indices of pipes and conduits as criteria by which to assess the effectiveness of the object in the design of piping systems. Based on the analysis of statistical data and regulatory requirements for the selection of the range of indicators of reliability of technical devices is justifiedthat the reliability of pipes and pipelines must be assessed indicators of longevity: Т*ср, Тсл, Тγ. If it isср сл γjudged piping system, such as conduits or piping distribution network, the reliability is taken as ameasure of P ( t ) - reliabilities for time t . It is proposed to the existing set of rules (SR) design water and wastewater systems to make the requirements for standardization and evaluation of the reliability of pipelines.
