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. Here is disclosed the fastener consisting of a support with cells for pipes and of a group grip overlapping the cells; the support has one common cell for each pair of pipes; the grip corresponds to a strip with stops entering between adjacent pipes of each cell, while base angles of the support are rounded and the strip of the group grip is made radial.

EFFECT: design of fastener of disclosed type facilitates reliable operation of spiral-like twisted pipe bank of high-heat area of heat exchanger of nuclear power installation, also facilitates their spacing and decreased hydraulic resistance.
