The paper presents the results of the experimental study of radial burning of holes in titanium samples simulating a fragment of the shell of a high-pressure tank filled with gaseous oxygen or oxygen-containing gas. The tests revealed the possibility of a large increase in the orifice area (140-2 250 times compared with the initial value) as a result of the burning of small through-holes when oxygen-containing gas of the increased pressure flows through them and allowed us to determine the apparent radial burning rate at various oxygen concentrations. The proposed mathematical dependence of the hole size in the titanium shell after their radial burning on the process parameters may be of interest for the analysis of processes occurring in engineering systems in case of some off-nominal and emergency situations.
