FIELD: machine building.
SUBSTANCE: method for forming the pipe ends in the pressure vessel necks includes heating the pipe end and its breaking-down in a die, moving the pipe through the heat exchanger arranged above the melt surface and into the melt of a substance with melting point corresponding to the pipe material superplastic state. The pipe end breaking-down is carried out by combining the pipe dead weight effect and ultrasound in the aforesaid die placed on melt bath bottom.
EFFECT: higher quality of structure of pipe material broken-down in pressure vessel neck.
