Block thermal insulation piping device

Abstract

The present invention relates to nuclear kinetics, and in general, to heat exchange equipment for nuclear power plants, particularly for pipe insulation and reactor plant equipment. The technical achievement of the invention is to reduce equipment material consumption, reduce heat loss, and simplify device installation and device maintenance. The result of this technology is that in block thermally insulated pipes, separate blocks are installed in the form of corrosion-resistant stainless steel welded boxes including the outer surface of the pipe, the interior of which is thermal insulation material, interconnected using high-speed fastening locks, and, The joints of these blocks are covered by gaskets. It is recommended to use a set of at least three layers of heat shields made of corrugated stainless steel corrosion-resistant sheets as insulation materials to form a closed air cavity. The outer wall of the adjacent block The plate is shorter than the length of the block itself than the size of the gasket, and is installed on the air gap on the air opening side of the outer surface of the baffle cover. The gasket is made of multi-layer stainless steel corrosion-resistant thin corrugated steel in pairs. , The combined parts are connected by high-speed fastening locks, and the width of the covering gasket covers the high-temperature area of ​​the block at its joint. As an option, these blocks are jointed along the axis with ledges. As an option, the joints of the blocks should have rough surfaces, especially the joints of the blocks should be made of stainless steel corrosion resistant sheet corrugated steel. As an option, the internal length of the block should be less than the external length of the block, expressed in terms of thermal expansion. As an option, these blocks are fitted with an air gap from the pipe.

Description

technical field [0001] The present invention relates to nuclear kinetics, and in general, to heat exchange equipment for nuclear power plants, particularly for pipe insulation and reactor plant equipment. Background technique [0002] A technical solution is known, which discloses a method for the insulation of pipelines by weakening radiation heat transfer heat insulation (Russian Federation Patent № 2219425, MPK F 16 L 59 / 06, priority 20 November 2002 day). [0003] The disadvantages of this device are: [0004] - the complexity of the organization of a large number of closed air cavities; [0005] - complexity of installation and maintenance of the installation; [0006] - Impossible to remove excess heat. [0007] Known technical solution "High temperature insulation", where the insulation is made with a set of alternating corrugated and foil shields of different thicknesses (application 2003106471 / 06, MPK 16L59 / 06, F16L59 / 08, 2003 27 September). [0008] The disad...

Problems solved by technology

[0018] These disadvantages are due to the fact that the fibrous material is used as insulation, moreover, the design does not provide for the removal of excess heat at the joints of the blocks during the operation of the switchgear
