Abstract
Given are the results of calculation of stressed state of the wall of a coiled tank with a capacity of 50,000 m3 in welding-in of insert plates. Theoretical estimation of the possibility of loss of stability of the wall due to the effect of residual welding stresses is presented. It is shown that the welding technology recommended by standards fails to provide retention of the designed geometrical shape of the wall in the case of replacement of its vertical assembly welded joints arranged in line by joints with the welds separated in chords.
Keywords: overhaul, vertical cylindrical steel tanks, coiled billets, vertical assembly joints in wall, welding stresses, stability
