FASTENER Russian patent published in 2010 - IPC F28F9/00 F28F9/13 

FIELD: machine building.

SUBSTANCE: invention refers to heat engineering and can be implemented at fastening bank of spiral-like twisted pipes of high-heat area of heat exchanger of nuclear power installation. The fastener consists of a rim with rows of strips arranged parallel in each row and at angle relative to each other in adjacent rows; the strips have sections of contact with pipes; also the strips in each row are inclined relative to lengthwise axis of pipes; sections of strips contact with pipes in each successive row are set off relative to sections of contact of the preceding row around spiral line.

EFFECT: design of fastener of disclosed type facilitates reliable operation of heat exchanging pipe bank of high-heat exchanger of nuclear power installation due to close distancing of pipes and also due to elimination of pipe vibration.
