REFLECTIVE BLOCK THERMAL INSULATION FOR PIPELINES AND / OR EQUIPMENT OF REACTOR PLANTS Russian patent published in 2021 - IPC F16L59/06 

FIELD: nuclear energy.

SUBSTANCE: invention relates to nuclear energy, namely to heat exchange equipment of nuclear power plants, in particular to thermal insulation of pipelines and equipment of reactor plants. Block thermal insulation of a reflective type for pipelines and / or equipment of reactor plants, containing multilayer packages of thin sheets of stainless steel, separated by air gaps, placed on the outer surface of the pipeline and / or equipment of reactor plants, according to the claimed invention, multilayer packages of thin sheets of stainless steel are made in the form of removable boxes, forming paired blocks connected to each other by quick-acting tension locks, made in the form of the condition of maximum adherence to the surface of the pipeline and / or equipment of reactor plants, while the multilayer package inside the box and the inner surface of the boxes of the paired blocks are made of corrosion-resistant thin sheet bulged steel sheets, and the sheets of the multilayer bag of bulged thin stainless steel sheet are installed with a variable air gap. The multilayer package inside the block is made of oppositely directed U-shaped sheets of rolled thin sheet stainless steel, connected from the fold side with the block box. The blocks are installed with an uneven air gap along the joint surface of the ducts. Paired blocks of block thermal insulation are installed around the pipeline and / or equipment of the reactor plants with an air gap.

EFFECT: invention provides a decrease in the material consumption of the device, a decrease in heat losses and a simplified installation and repair of the device, a decrease in the risk of fire.
