摘要：

The paper is devoted to the issues of experimental analysis of residual stresses on the concrete part of pipelines - welded ball valve. A semi-destructive hole-drilling method was used for measurement, and experimental stress analysis and evaluation of residual stresses was made in accordance with the US standard ASTM E 837 - 01 [1], as well as with use of an integral method [2]. Residual stresses were measured both immediately after welding and after pressurising of the ball valve. This has enabled observation of the influence of pressurising 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.
