New aluminum alloy brazing sheets are disclosed. The new aluminum alloy brazing sheets may include a core, an interliner layer adjacent the core, and a braze liner adjacent the interliner layer. The interliner layer may include a first aluminum alloy having at least 0.35 wt. % Si and from 0.05 to 2.0 wt. % Mg. The braze liner may include a second aluminum alloy having 0.05 to 2.0 wt. % Mg. The first aluminum alloy and the second aluminum alloy may include an amount of magnesium sufficient to achieve T(IL)&#x2265;5&#xb0; C. T(BL). The new aluminum alloy brazing products may be useful, for instance, in fluxfree brazing.

Aluminum alloy brazing sheets for fluxless brazing

In one embodiment, the present invention relates to a riser apparatus for use in offshore drilling for oil or other fossil fuels, the riser apparatus comprising: a plurality of riser sections coupled serially end-to-end, wherein each of the riser sections comprises: a tube having a first end and a second end; a first flanged that is mechanically joined to the first end of the tube; a second flanged that is mechanically joined to the second end of the tube; wherein the tube is constructed of an aluminum alloy; and wherein the flanges are constructed of the aluminum alloy; and wherein the riser apparatus has a length of approximately 1,500 meters or greater.

Method and apparatus for connecting drilling riser strings and compositions thereof

A packaging unit () for containing, for example cigarettes () has a body made of curved metal () and curved metal back () surfaces connected by metal sides (), and a metal bottom (), preferably having a central raised exterior part or bottom () surrounded by a ridge (), with a lid () having a straight hinge () across the top, where the unit is capable of hermetic sealing.

Curved back reclosable metal packaging unit

A sheet metal end shell for conversion into easy opening beer and beverage ends with reduced metal usage while maintaining commercially acceptable buckle resistance. The end shell has an upper chuckwall portion that is disposed at an angle of about 20-35 degrees to vertical, a countersink bead having a width of about 0.020-0.040 inch, and further preferably having a countersink depth of less than about 0.250 inch and a panel depth less than about 0.070 inch.

Metal end shell and easy opening can end for beer and beverage cans

The invention hereof is directed to a continuous casting of flat rolled sheets selected from automotive sheet, can body sheet, and endstock which exhibits properties comparable to the same products made from World Class Ingot. A preferable embodiment for the continuous caster is a vertical continuous caster.
