The customer places high demands to this equipment:

- warranty service life of gates to the boundary state of at least 35 years;

- warranty period of the anti-corrosion protection system for gates is at least 15 years;

- the work is performed on the object representing an increased environmental hazard.

Production of such critical equipment is possible only at a specialized enterprise, equipped with the necessary technological equipment, machine park and qualified engineering and technical personnel, who will ensure proper preparation of production, development of necessary executive documentation, compliance with the requirements of current regulatory and governing industry documents in all parameters.

The contract with UKRHYDROENERGO also provides for the reconstruction of the embedded parts of the three spans of the dam, as well as the installation of the produced gates, which will start according to the schedule of works in the near future.

In the long history of UKRSTAL CONSTRUCTION it has accumulated invaluable experience in the production and installation of such ultra-reliable hydraulic engineering equipment: in 2007, 2008, 2010, similar projects were repeatedly implemented throughout the Dnieper cascade for the Kremenchug, Dneprodzerzhinsk, Dneprovkaya, Kakhovskaya, Kanevskaya, Kiev hydropower stations.

Technological map of the production of this order involves the use of the most advanced and technically sophisticated methods of metal processing, the equipment includes not only welded metal structures, but also components made by casting, forging, followed by mechanical and heat treatment to achieve guaranteed equipment performance parameters. After complete welding of the seams of bolts, diaphragms, stringers and ultrasonic testing, the construction will proceed in several stages to a control blot assembly with installation of mounted components (balance carts, compactors and other components). After acceptance by the Customer, Developer and Installer, there follows the disassembly, anti-corrosion coating, shipment to the site, where our installers UKRSTAL MONTAZH will perform a pre-installation revision, assembly welding in assembly mode into a single GATE mechanism, install rubber seals, conduct ultrasonic testing and apply finishing coatings, and then provide equipment installation and commissioning.

All work is carried out in a coordinated interaction with the Customer UKRHYDROENERGO and the Developer of design documentation - SPKTB ZAPOROZHHYDROSTAL - the leading specialized organization of Ukraine performing a set of works on design, engineering, author supervision and inspection of mechanical equipment and special steel constructions of hydrotechnical structures of power engineering facilities, land improvement and water farms.

UKRSTAL CONSTRUCTION with full responsibility approaches the implementation of significant national projects that ensure the smooth operation of the energy system of Ukraine, recognizing its role in the economic growth and welfare of the country. The team of UKRSTAL CONSTRUCTION expresses deep gratitude to the Partner - the company UKRHYDROENERGO for their confidence and will continue to work hard to complete the production task.
