Abstrakt: The performed research helped to develop and implement a new process of manufacturing small high pressure cylinders, in which the operation of pressing of tubular blanks with preliminary induction heating of the deformation zone. A two-layer inductor was designed and an industrial unit for preliminary differentiated induction pre-heating for the developed technological process. The forming rate was determined, ensuring preservation of the specified temperature difference and manufacturing of deformed tube end in accordance with the requirements for its geometry. Heating die-blocks were designed for blanks deforming for application in manufacturing of diameter, allowing keeping the necessary temperature gradient at deforming. Developed technological lubricants can be used for obtaining high quality products, increase in labor protection and die-blocks durability.
