Abstract: Modular heat insulation, manufactured as separate welded blocks of stainless corrosion-resistant steel, arranged on the pipeline outer surface. The boxes are filled with heat-insulating material and interconnected with quick-acting tension locks. The cover plates shield the block joints. A heat-insulating material being a set of minimum three corrugated or blistered shields is used. These shields are manufactured of stainless corrosion-resistant steel forming enclosed air cavities. The external lining sheets of the adjacent blocks are shorter than the blocks themselves by the size of the cover plates and are installed with a lateral ventilated gap from the external surface of the shield set. The cover plates shall have the shape of mated sections with a multilayer set of corrugated stainless corrosion-resistant steel sheets. The mated sections are quick-acting tension locks, and their cover plates have width overlapping the area of blocks' increased temperature within their joints.

Abstract: A bath electrical heating device for deactivation designed to provide heating of bath deactivation and the deactivating solution in it before deactivation of reactor facility equipment and ensuring the removal of excess heat in the process of deactivation. The invention improves reliability, reduces the material consumption of the device and simplifies the structure installation and repair. The device performs at least from three heat insulation blocks in the form of coaxial metal screens, installed with an air gap from the heater. The heater with current leads is made in hermetic perform, each heat insulation blocks supplemented with an air-gap coaxial metal protective casing. The air gap of which in the upper part is covered with a cap with a visor whose diameter exceeds the external diameter of the protective casing, wherein solid cover of the upper protective casing install a sealed coupling.

Abstract: The invention relates to nuclear power, in particular to electric heaters in the safety systems of nuclear reactors of nuclear power plants. The object of the invention is to improve the reliability of nuclear power plants. The technical result is achieved in that the busbar unit is tubular, containing a block of tubular heaters, sealed terminal box, the connection nodes of the power wires to the output tubular heaters, which are combined in groups, the node connecting the wire supply to the output tubular heaters made in the form of a heat-resistant sealed plug bayonet connector, plug which is the output tubular heaters, pins bayonet connections are made on the body of the tubular electric heater, and the grooves of the bayonet connection are made in the form of an inclined profile surface.

Abstract: The present invention provides a device that reduces thermal influence from heated elements of equipment on the findings of the tubular electric heater and lowers the temperature of the host electrical connection. Tubular unit heaters include flange (cover) with threaded holes and bushings, which are rigidly sealed tubular heaters with the conclusions and findings of the tubular electric heater made of electric portable node connections, and protective jacket, which is mounted on the flange from the insights of the tubular heater, offered on the module flange tubular electric heaters, from the insights of tubular electric heaters, set the cylindrical shell, on the upper half of which to perform a through perforation, on the inner surface of the cylindrical shell rigidly fix at least two heat shields with holes for tubular electric heaters, and the diameter of the holes in the heat shields should exceed the outer diameter of the sleeve.
