  • a reliability assessment of the hydrostatic test of Pipeline with 0 8 design factor in the west east china natural gas Pipeline iii
    Energies, 2018
    Co-Authors: Lei He, Weichao Yu, Jing Gong
    Abstract:

    The use of 0.8 design factor in Chinese Pipeline industry is a breakthrough with the success of the test Pipe Section in the west–east China gas Pipeline III. For such a design factor, the traditional P-V (Pressure-Volume) curve based pressure test control cannot describe the details of the process, and the 0/1 type failure is not an efficient index to show the safety level of the Pipeline. In this paper, a reliability based assessment method is proposed to monitor the real-time failure probability of the Pipeline during the hydrostatic test process. The reliability index can be used as the degree of risk. Following the actual hydrostatic testing of a test Pipe Section with 0.8 design factor in the west–east China gas Pipeline III, reliability analysis was performed using Monte Carlo technique. The basic values of input parameters of the limit state equations are based on the data collected from either the tested Section or the recommended value in the codes. The analysis of limit states, i.e., the yielding deformation and the excessive plastic deformation of Pipeline, proceeded based on these distributions. Finally, it is found that the gradually increased water pressure makes the failure probability increase accordingly. A reliability assessment method was proposed and illustrated with the practical pressure test process.

  • correlation and capability of using site inspection data and small specimen creep testing for a service exposed crmov Pipe Section
    Materials at High Temperatures, 2019
    Co-Authors: B Cacciapuoti, D G Mccartney, A Morris, Jeff Hulance
    Abstract:

    ABSTRACTThis paper presents for the first time an investigation on the creep damage evolution of an ex-service CrMoV Pipe Section through impression creep test (ICT) and metallurgical inspection data. The study emphasises the importance of correlating the operating conditions (temperature and stress) of power plant components with the results from metallurgical examinations and small specimen creep tests. The paper seeks for a correlation among micro- and macro-hardness measurements, surface replicas data and minimum creep strain rates (obtained by ICTs) of the parent material of the Pipe Section. Also, optical and scanning electron microscope (SEM) micrographs have been used to assess possible metallurgical differences through the thickness of the Pipe Section. This investigation shows how miniature creep test specimen data could be practically used in a holistic approach for the evaluation of life consumption of power plant components and concludes that the studied parent material could have been retire...
