On the basis of piezomagnetic method the mathematical model have been designed for determining residual stresses in welded junctions of gas-main pipeline. We have also developed the mathematical model that allows to investigate the stress state of gas pipe with subtle defects and inclusions. The received results give the chance to develop the corresponding methods of technical diagnosing of pipelines, an assessment of their residual resource on strength.
