Sulfide stress cracking (SSC) is one of the most dangerous types of pipelines destruction. Thermal impact of the welding process drives to heterogeneity of the microstructure and properties of the metal, which can lead to cracking of pipeline welded joints. Resistance to SSC of welded joints is determined by the thermal cycle of welding and cooling rate in the temperature range of austenite transformation. Due to performed studies based on simulation of welding heating the recommended range of cooling rates of 10–30 ° C/s was established, in which the resistance to SSC of welded joints is ensured. To calculate the cooling rates in coarse grained heat affected zone (CGHAZ) finite-element models of heat distribution were developed for longitudinal multi-electrode submerged arc welding (SAW) and multi-pass girth welding of pipes. Using the developed welding models, it was found that in order to achieve the cooling rate in CGHAZ it is necessary to reduce heat input up to 15-30% during multi-electrode SAW process of longitudinal welds of pipes . For multi-pass girth welding it is necessary to preheat the edges to be welded up to 100-300 °C depending on type of welding (GMAW or SMAW) and pipe wall thickness.

The creation of electrical facility modern dispatching system in an industrial enterprise should be part of the overall digitalization strategy, ensuring reliable and safe operation of electrical installations, which in turn will have positive impact on the competitiveness of industrial enterprise. The article describes the principles and algorithms for constructing of electrical facility monitoring and control system on the example of metallurgical enterprise. It is described the pilot project of the plant's electrical facilities dispatching control implementation, defining ecological safety. One of the significant results of the dispatch system introduction for the sulfuric acid subdivision is to reduce technological equipment downtime by 30%. The stages and tools for improving the operational and dispatch management of the enterprise's electrical facilities are developed. The developed system of the company's electric facilities dispatching, combining information channels with three major downgrade substations, will allow solving the problems of electrical parameters, monitoring of the substation equipment state, and controlling the load of transformers, switching equipment. In addition, it becomes possible to control the specific electricity consumption of the main process equipment and efficiently to plan electricity when working in the wholesale market, as well as to increase the speed of decision- making to eliminate and prevent unwanted operating modes.

Development of Satka magnesite deposit is carried out in complicated geomechanical conditions, in particular, mining works are conducted under the Bolshaya Satka river, in the zone of influence of the existing and developed quarries. Underground workings undermine a number of surface objects of industrial and civil purpose: railways, bridges, buildings and structures. There was an urgent need to conduct special studies of geomechanical conditions at the mine in order to assess the feasibility of working off part of the safety pillars located under the railway tracks of "Russian Railways", PJSC and the river bed. In the process of research, the main physical and mechanical properties of rocks have been identified, and the initial natural stresses of the rock mass have been measured. An increased level of horizontal initial stresses in the zone of safety pillars at the horizons + 180. + 260 m was detected. Based on the results of the research, a conclusion was made on the need to develop some engineering measures to ensure the safety of underground works. It was recommended, to ensure the stability of the rocks massif, to apply the option of extracting the treatment chambers with the formation of the ceiling of the vaulted form. It is proposed to monitor deformation processes in mine workings and on the daylight surface. To this end, the installation of an automated control system for rock pressure is recommended. It is necessary to provide for the establishment of long-term observation stations for controlling rock pressure and displacement. According to the results of the research, "Guidelines for the safe control of mining operations at bump-hazardous Satka magnesite deposit" have been developed in accordance with the requirements of the Federal norms and regulations in industrial safety.
