FIELD: heat power engineering.
SUBSTANCE: method comprises setting the core and ribs into the piping blank. The core is hollow, and each of the ribs are made of a hollow body defined by the rotation of a figure composed of the straight sections interconnected to form a hexagon. After setting the ribs, they are subjected to the flexible deformation by bringing the sides of the rib together. The sides of the ribs are perpendicular to the axis of the pipe and point in the direction of the pipe axis.
EFFECT: enhanced efficiency.
