The article provides the information on a promising technology for trenchless repair named Swagelining, which supposes pulling into the old pipeline the new polymer with its preliminary thermo-mechanical compression and further straightening. The coauthors present the results of the calculations determining the thickness of the polyethylene pipes after compression and straightening in the old pipeline depending on the initial diameter in case of different ratio of the diameter to the wall thickness (SDR) and the dynamics of the changes in hydraulic performance after repair work on the pipeline using the method Swagelining. The concept of the energy saving potential is formed in addition to a no-dig repair for pressure piping systems, water supply, and its magnitude. On the basis of the research results, the authors formulate the principles of the energy efficiency potential after the implementation of the trenchless technology of drawing the old pipeline with new polymer pipes with their preliminary thermo-mechanical compression and subsequent area enlargement. The technology Swagelining is described and the authors develop a mathematical model that illustrates the behavior of the pipeline in the process of shrink operations. Such parameters are analyzed as changing the diameter of the pipeline at thermo-mechanical compression, the hydraulic parameters of the new (polymer) and old (steel) pipelines, energy savings on one-meter length of the pipeline. The calculated values of the electric power economy on the whole length of the pipeline repair section with a corresponding flow of transported waters.The characteristics and capabilities of the technology of trenchless renovation Swagelining allows achieving simultaneously the effect of resource saving (eliminationof the defects and, as a consequence, of water leakage) and energy saving (reduction in the water transportation cost).A numerical example of the old steel pipeline renovation shows the calculated data, which proves the efficiency of the considered technology. The calculation results can be used as base material for designers when selecting the final decision of the alternative at reconstruction of dilapidated pipelines by Swagelining using a wide range of polymer pipes with the corresponding value of the SDR.

The authors present an analysis of various types of internal protective pipeline coatings to ensure the strength and hydraulic characteristics of a remodeled pipeline and related coating methods for effective trenchless renovation of engineering systems, water supply systems and sanitation. As protective coating the authors considered a round profile tube of a smaller diameter than of the old pipe, close to the old pipe, sprayed lining on the basis of inorganic and inorganic materials. The article analyzes the methods of trenchless renovation for applying protective coatings: routing in the old pipeline of new pipes made of polymeric materials or polymeric sleeves, centrifugal spraying on the inner surface of pipelines’ inorganic and organic protective coatings. Special attention was paid to bag technology, providing the required strength properties at specific values of the modulus of elasticity and a number of external factors such as the depth of the existing pipe, the existence and magnitude of the horizon groundwater over it. Also attention is paid to the application technology of tape coatings ribbed profile on the inner surface of pipelines. This technology has a unique feature, which is the ability of recoverable pipeline functioning during its renovation by winding an endless belt and the formation of a new pipe. The tape coating winding is carried out by different types of spiral winding machines. The thickness of the protective coating layer forming the tube remains minimal. Inorganic cement-sand and organic coatings were considered as alternative options for repair of pipelines, which allow to localize the defects in the form of a fistula, minor cracks and other damages. However it is noted that a cement-sandy covering is inferior to organic, because it does not provide the strength characteristics of the pipeline system. The main advantage of the organic coating is mudding fistula of a large diameter, making a high wear-resisting pipe, ensuring a smooth surface. Then the protective coating almost merges with the old pipeline. The conclusion is made on the necessity of taking account of the potential for energy saving in case of various protective coatings and implemented trenchless technologies application.

Swirled flows of liquid and gas are widely used in modern technology because of many of their unique aerodynamic, thermodynamic, and hydro-mechanical qualities. They are used for spraying liquid fuel mixing and dispersing liquid, aerosol formation, formation of the flame, classification of disperse materials and drying, dehydration, deaeration, cooling and heating, distillation and purification (rectification of working fluids), ash and dust-collecting, generating vapor separation of suspensions, absorption materials, separation materials, excitation of mechanical vibrations and formation of a sound signal, transportation of materials and many other technological purposes. The proposals for the use of interacting (counter vortex) swirling flows were caused by the requirements of the practice of mixing fluids and gases and quenching of excess kinetic energy of the high-speed flow of water in the high-pressure hydro spillways. The method for energy dissipation by reacting flows (jets) I based on the idea of separating the stream into parts and creating the conditions for mutual energy damping of individual parts of during subsequent reunification. As it is known, while moving from the upper pool to the lower one the water flow may dampen its energy performing useful work on the hydraulic turbines or overcoming the reaction forces, which arise when passing through the dampers. The energy of one part of a stream in interaction with the energy of the other part is used for creating the forces equivalent to the jet forces developed by quenchers. Such interaction can give the best effect in the conditions of rational breakdown of a stream and creation of the respective movement directions of its parts in relation to each other. In the cylindrical camera of counter vortex devices coaxial flows are formed consisting of two or more oppositely swirling flows of liquid or gas, the interaction of which can convert practically the whole mechanical energy source of the interacting flows into excess turbulence energy. The nature and intensity of hydro-mechanical, aerodynamic and mechanical processes occurring in the counter vortex devices provide the efficiency of their application in various branches of modern technology for mixing of single-phase and multiphase media, quenching the excess mechanical energy of the flow of liquid and gas, for disintegration of conglomerates, creating a homogeneous systems, excitation of mechanical vibrations and obtaining other effects. Authors due to the nature of their activity paid the main attention to the development, researches and creation of the designs of counter vortex quenchers of spillways energy of high-pressure water-engineering systems and counter vortex aerators of different purpose. Counter vortex devices have been tested for other purposes (homogenizer, flotators), protected by patents or circuit diagram are proposed for them.
