Patent CA-2357724-A1 (CA)
Title: A method of manufacturing a metal pipe with an eccentrically expanded open end
Inventor: ISHIKAWA HANJI
IPC: B21D41/02
Filed: 2001-09-24
Abstract: At first, an open end of an original metal pipe M is plastically deformed to such the coaxially expanded state M1 that axial wall length L2 at a side to be eccentrically expanded is longer than axial wall length L1 at the opposite side to be expanded without eccentricity. The coaxially expanded open end M1 is then plastically deformed to an eccentrically expanded state M2 by forcibly inserting an eccentrically expanding punch 20 into the coaxially expanded open end M1. The eccentrically expanding punch 20 has a boundary 23 between a conical tip 21 and a cylindrical body 22 inclined with a predetermined angle .theta. so as to bring the cylindrical body 22 into contact with an inner wall of the coaxially expanded open end M1 at a side to be eccentrically expanded earlier than the opposite side to be expanded without eccentricity. When the coaxially expanded open end M1 is plastically deformed to an eccentrically expanded state M2, metal flow is suppressed at a side to be eccentrically expanded, but metal flow from the opposite side to be expanded without eccentricity to the former side is promoted. Consequently, the open end is plastically deformed to the eccentrically expanded state M2 without thickness deviation along a circumferential direction.

Abstract: The process and the apparatus are used to obtain argon using a three-column system for the fractionation of air, which has a high-pressure column (11), a low-pressure column (13) and a medium-pressure column (12).      A first charge air stream (10, 64) is introduced into the high-pressure column (11), where it is separated into a first oxygen-enriched liquid and a first nitrogen top gas. A first oxygen-enriched fraction (23, 24, 26) from the high-pressure column (11) is introduced into the medium-pressure column (12), where it is separated into a second oxygen-enriched liquid and a second nitrogen top gas. A second oxygen-enriched fraction (33, 35), from the high-pressure column and/or from the medium-pressure column (12), is introduced into the low-pressure column (13), where it is separated into a third oxygen-enriched liquid and a third nitrogen top gas. An argon-containing fraction (68) from the low-pressure column (13) is introduced into a crude argon column (70), where it is separated into a crude argon top fraction and an oxygen-rich liquid. At least a part (73) of the crude argon top fraction (71) is passed into a crude argon condenser (29), where it is at least partially condensed by indirect heat exchange with at least a part (27) of the second oxygen-enriched liquid from the medium-pressure column (12).
