Vessels and apparatus employed in the chemical and petrochemical industry (containers, heat exchangers, towers, scrubbers, reactors, tanks, and pipelines) do not contain redundant components; safety factors assigned during design for cases of wear, degradation of material properties, and other unforeseen situations therefore ensure their safe-operating lives. A reduction in safety factors will make it possible to judge how closely structural components and production equipment as a whole approach the limiting state. The standard safety factor serves as a reference point indicating just how closely the actual safety factor comes to the limiting state, and in the author's opinion, can be adopted as the limiting allowable safety factor ensuring the safe operation of production equipment. Reserve-strength investigations conducted by the Angarsk Petrochemical Company over a number of years have demonstrated the versatility of dimensionless values of design, actual, and standard safety factors, and the possibility of their use as indicators for evaluation of overall, computed, (allowable) and remaining service life. Evaluation of the overall, computed (allowable), and remaining service lives is acceptable for design, fabrication, and appraisal of industrial safety as a technico-economic indicator serving to define safe-service lives assigned to production equipment. © 2011 Springer Science+Business Media, Inc.

A new version of a regulation of output and product quality in coke making of various residues in oil refining and petrochemical industries was suggested. Regularities of a hydrogen effect on the carbonization yield and an amount of sulfur in it were found. © 2010 Pleiades Publishing, Ltd.

A mathematical model is proposed for investigating the effect of parameters of welding with the energy of electrical explosion of a conductor on the quality and reliability of tube–tube plate welded joints. The possibility of controlling the parameters of collision by regulating the angle of preparation of the orifice in the tube plate and the parameters of the discharge circuit of electrical engineering equipment (EEE) are discussed. Combined preparation of the orifice in the tube plate is an efficient method of increasing the quality of the investigated welded joint. © 2014, © 2014 Taylor & Francis.

A concept of methodological recommendations for estimating service life for designing, fabricating, and appraising safety of industrial equipment is proposed. The degree of wear, which characterizes the change in safety (strength) margins of components, parts, and units (assemblies) in the process of their operation, is taken as the generalized parameter. The concept solves the problem of estimating the full, residual, calculated (permissible) service life of industrial equipment that does not have backup (standby) components. © 2012 Springer Science+Business Media, Inc.

Transfer pipelines are developed for the supply of feedstock from a furnace to a fractionating tower. A feature of the development is absence of temperature compensators and preliminary loading of pipelines. In order to monitor stresses that may arise in the area of pipeline setting into a K-11 tower, and their movement, a comprehensive diagnostic monitoring system has been developed with the possibility of remote control, inspection and analysis of the monitored parameters. © 2012 Springer Science+Business Media, Inc.
