FIELD: machine engineering, possibly manufacture of fittings, namely body parts of pipeline fittings.
SUBSTANCE: sheet blank with central through opening and different thickness is heated and placed in die set for forming bottom and branch pipe of body part without replacing blank. Bottom of body part is drawn with use of drawing punch and branch pipe is formed by flanging.
EFFECT: improved operational reliability, enhanced strength of body parts, lowered metal consumption, simplified process of making such parts.
