  • Integral joint forming of work-hardenable high alloy tubing
    Patent number: 4747431
    Abstract: A method of fabricating a tube having enlarged ends and made of material which can be strengthened by cold working comprises fabricating a pre-form having the overall configuration of the tube but with increased outside diameters and a decreased length. The pre-formed tube is cold forged or cold rolled over its entire length to reduce its outside diameter while maintaining its inside diameter substantially fixed. This elongates the tube and reduces its cross-sectional area. Cold working is continued until the final desired dimensions for the tube are reached. This produces a strengthening effect by cold working over the entire length of the tube.
    Type: Grant
    Filed: December 19, 1986
    Date of Patent: May 31, 1988
    Assignee: The Babcock & Wilcox Company
