VIBRATORY STRESS RELIEVING OF TANK FLANGS

1. Nedeljko Vukojević

The procedure of residual stress relieving on structures can be done in several ways, the best results can be achieved with heat annealing treatment, but due to limitations on the dimensions of structures that need to be treated alternative methods have been developed. One of these alternative procedures is vibrational relaxation process. The paper presents method and results of performing the vibrational relaxation of residual stresses. Measurements of residual stress are made i.e. the definition of \"zero state\" as well as measurement of changes in residual stress caused by vibrational relaxation, which was performed in order to eliminate or decrease the size of residual stresses in the zone of welds flanges and vertical tanks with floating roof.
