The present invention relates to an aluminum alloy brazing sheet (1) for a heat exchanger improved in a life including a fatigue in a plastic area and an aluminum alloy heat exchanger tube (11) using the brazing sheet, which is composed of:a core material (2) of an AlMn series alloy; a skin material (3) of any one of an AlZn series alloy, an AlZnMg series alloy, an AlSiMnZn series alloy, and an AlSiMnMgZn series alloy
A. Qualify soldering processes, procedures, and solderers for copper and copper alloy pipe and tube in accordance with ASTM B 828. B. Qualify brazing processes for copper and copper alloy pipe and tube according to ANSI/AWS C3.4. 1. Qualify brazing procedures and brazer performance in STEEL TUBE AND PIPE HANDBOOKTube classification goes out several aspects:mode of produc-tion, cross section shape, tube ends treatment, sphere of tube usage. According to EN 10079 tubes rank among so-called long prod-ucts. It is a product having permanent circular or another hollow section along, with both ends free and with relatively long length.
Feb 10, 2004 · Basic Principles of Tube Expanding Tube Expanding is the art of reducing a tube wall by compressing the O.D. of the tube against a fixed container . . . such as rolling tubes into tube sheets, drums, ferrules or flanges. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage. US4754635A - Device for drape drawing a shadow mask for Abstract.
