Abstract
The paper presents the results of experimental investigations of the residual service life of shop vertical butt welded joints of 16G2AF steel on a coiled tank wall after 20-25 years of service. No changes of mechanical properties with time were found, including their cold resistance. It is established that the studied welded joints have the residual service life sufficient for their further operation for not less than 20 more years.
