摘要： 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.

摘要： A method of prestressing a tubular apparatus having coaxial inner and outer tubes which are connected to each other at axially spaced locations comprises, after the inner and outer walls are connected to each other and the tube is heat-treated or otherwise processed, reducing the diameter of the outer wall so that the outer wall is elongated. The elongation of the outer wall establishes a prestressed condition between the inner and outer walls, with the inner wall under tension and the outer wall under compression. The reduction in diameter of the outer wall can be accomplished by using a roll extrusion machine, a tube reducer or a draw bench.

摘要： A method of prestressing a tubular apparatus having coaxial inner and outer metal tubes which are connected to each other at axially spaced locations. After the inner and outer tubes are connected to each other so that the tubular apparatus may be heat-treated or otherwise processed before it is prestressed, the diameter of at least a portion of the inner tube is increased so that it is shortened to thereby establish a prestressed condition between the inner and outer tubes with the inner tube under tension and the outer tube under compression.

摘要： A method of constructing a nozzle having cooling channels comprises a shell and a liner which are formed into a body of revolution having an axis of revolution. Helical welds are formed to hold the liner and shell to each other with a channel position being defined between each pair of helical welds. Pressurized fluid which may be a gas or a liquid, is introduced between the weld pairs to outwardly bulge the material of at least one of the liner and shell to define the channels.

摘要： A reinforced hydraulically expanded flow channel (18) is disclosed which prevents the width of the hydraulically expanded flow channel (18) from changing. This reduces the strain rate in the high strain area next to the welds (16). After the hydraulic expansion process, the ends (20, 22) of the hydraulically expanded flow channel (18) are restrained by a rigid structure (24) such as a tubular member (28). When a tubular member (28) is employed, additional support is provided opposite the desired heat transfer surface (26).
