ABSTRACT:
A tubular part formed by superplastic forming has a tubular structure made of superplastic material having a tubular wall with an outside surface like an inside surface of a die against which the tubular wall was superplastically formed by heating to superplastic forming temperature, and injecting the forming gas through connectors in end portions of the tubular structure, sealed against escape of forming gas from the tubular structure, to inflate the tubular structure against the inside surface of the die. Two open ends at opposite ends of the tubular wall are made by cutting off the end portions of the tubular structure. An integral projecting pull-out in the tubular wall for connection to a connecting tube is formed simultaneously with the tubular wall against a concave shape on the die.
