    Abstract. Regulatory documents for the construction of large vertical steel tanks contain a requirement for the need to perform heat treatment of large-sized structural units of manhole inserts and branch pipes in the wall sheets. This technological operation requires high costs and, at the same time, it is characterized by a number of disadvantages. In addition, there are stressed nodes in the tanks, for stress relief in which it is almost impossible to use heat treatment. It is proposed to use alternative methods of reducing residual welding stresses in the manufacture and installation of tanks, as well as to apply welding technologies that ensure a low level of residual stresses. The experience of using ultrasonic shock treatment and low-frequency vibration treatment of various types of welded structures is described. Specially developed welding technologies that ensure a low level of residual stresses without heat treatment must be certified with the measurement of the actual residual welding stresses in the welded joints of the corresponding structural units of the tanks. The certificate of attestation of such a technology should indicate the area of its distribution by steel strength classes, thicknesses of welded elements and types of welded joints. Proposals have been developed for adjusting regulatory documents aimed at improving the reliability and durability of vertical steel tanks.
