“…Nowadays, the majority of published articles concerning the effect which hydrogen has on embrittlement, hardening, fatigue, yield of structural elements point out to its negative impact on those processes [5][6][7][8]. Affected by hydrogen, metals undergo degradation of various types (hydrogen embrittlement, hydrogen corrosion, etc), which leads to catastrophic results [9,10]. Global statistical data indicate that, for the last thirty years, the number of accidents in oil and gas field has risen three times, but the damage from them has seen an increase of nine times.…”

A steadily rising interest which specialists in various fields show towards the problem of hydrogen affecting metallic materials and causing their failure is connected to all-increasing requirements set on the durability of machines and equipment in operation. Metallic structures are most often surrounded by such environment which contains hydrogenous components or hydrogen itself (in chemical industry, power engineering, etc). And it leads to various types of degradation in metals (hydrogen embrittlement, hydrogen corrosion, and so on), which, in its turn, could cause catastrophic results. Ultimate strength is considered to be a representative parameter of the process of hydrogen degradation in steels. The authors cite the results of testing conducted on hydrogen-saturated specimens made of A516-55 steel which register a significant decrease in the ultimate strength. It is proposed to use a diagram which describes a fall in metal strength and transition of structural materials into their brittle states following an increase in hydrogen concentration. Discussion is made on criteria for hydrogen-saturated materials of metallic structures failing when a momentary overload occurs under default working conditions.

Abstract. Corrosion damages of metal structures of wastewater treatment facilities affect the work process parameters and operation safety. The analysis of the factors causing corrosion of metal elements and the assessment of corrosion resistance of the steel grades St08ps, St3sp and St5sp during the treatment stages, including the chlorine treatment, were conducted based on the data obtained from the Rostov-on-Don aeration plant. The article search techniques to determine the corrosiveness of water towards the metal structures. It is established that in this case it is advantageous to use redox indicator systems (rH2), which is calculated on the basis of field measurements of redox potential (ORP) of water. Based on the conducted studies, the correlation dependence for determining the corrosion rate of the steel grades St08ps and St5sp was suggested and statistically assessed for the aeration plant structures.
