FIELD: production of T-pieces, cross pieces and other hollow branched parts. SUBSTANCE: method of shaping hollow branched parts from tubular blank with use of pressurized plastic viscous filler at simultaneously upsetting end of blank from the very beginning of shaping process comprises steps of uniformly lowering pressure in blank cavity until value being less than pressure breaking apex of branch. Pressure in blank cavity is reduced by throttling plastic viscous filler through small-diameter openings in ends of one or both punches. EFFECT: enhanced efficiency. 3 cl, 1 dwg
