FIELD: power engineering.
SUBSTANCE: steam generator pipe, where to create an internal profile that forms turbulence, at least one insert is installed in the internal space of the pipe, comprising multiple wires adjacent to internal wall of the steam generator pipe and having identical slope and arranged with the possibility of bending as the multiple thread in a helical manner lengthwise on the internal wall of the pipe.
EFFECT: simplification and reduced cost of steam generator pipes manufacturing with preservation of heat transfer characteristics.
