    Stress Analysis of Pipeline Valves

  • Original language description

    The contribution is devoted to the stress analysis of pipeline valves. Two types of pipeline valves were measured - the welded ball valve (Fig. 1) and the welded plate valve (Fig. 2). Results of the residual stress measurements will be given in this contribution only at the first type - welded ball valve. A semi-destructive hole-drilling strain gauge method was used for measurement. Residual stresses were measured both immediately after welding and after pressurizing of the ball valve. This has enabledobservation of the influence of pressurizing on change of residual stresses in the neighbourhood of the welded joint. Results of measurement of residual stresses served for further assessment of strength and service life of this component.
