ESTIMATING WELDED PIPELINE RESIDUAL LIFE ON THE BASIS OF HYDROGEN DEGRADATION OF THE METAL

摘要

Test results are given for specimens of steel 20 cut from industrial pipelines that had been operated for 16 or 24 years at a deposit in West Siberia subject to the action of a medium containing hydrogen sulfide. It is shown that there is a change in the degradation coefficients characterizing the cracking resistance distribution in the tube wall thickness.
