  • Publication number: 20120255927
    Abstract: A can or container reformed from an existing open ended can adds additional volume and integral thread portions to form a recloseable can. An existing can is inverted, drawn to increase the volume, an end wall pierced and reformed into an outwardly curled lip, thread portions formed along a perimeter portion of the can body adjacent a first end, and a new end seamed to the original open, second end of the can. A cap with thread lugs cooperates with the thread portions on the external perimeter of the reformed can to originally and subsequently reseal the can once the can has been opened.

  • Patent number: 8042368
    Abstract: To produce hollow profiles from sheet-metal blanks, the invention uses at least two process steps to form said blanks into a slit profile which is subsequently welded to produce the finished welded profile. For this purpose a mandrel is used which cooperates with a first tool part in the first step, and with a second tool part in the second step, such as to form a gap with the recess of each tool part into which a portion of the sheet-metal blank is guided. Shaping the sheet-metal blank in at least two steps means that a mandrel that is a self-contained component and can therefore be moved by a simple control device can be used to support the sheet-metal blank while the slit profile is being created. This considerably reduces the equipment needed to produce the hollow profile. Moreover, forming the sheet-metal blank into the slit profile in at least two steps also considerably improves the reliability with which this shaping takes place.

The sheet of metal is moved in a helical trajectory such that the second bend comes into proximity above the first bend. The second bend and the first bend are welded together such that the wall of the cylindrical tank is formed. Welding of the bends serves to stress relieve or anneal the bent metal, thereby preventing cracks in the metal which may result in leaks and/or compromise the structural integrity of the tank. The first and second bends additionally cooperate to form a helical roller track on the outside of the tank. The tank is supported and rotated about its longitudinal axis on a plurality of rollers that engage the roller track.

  • Publication number: 20100326557
    Abstract: The invention relates to a method for the production of hot-finished, particularly hot-rolled, seamless pipes having optimized fatigue properties in the welded state, having an outside diameter of up to 711 mm and a nominal wall thickness of up to 100 mm, made of metal, in particular steel. After hot or finish rolling, a defined pipe cross-section is produced on at least one pipe end across a predetermined length, having tight tolerances for inside and outside diameters, wherein the cross-section can then be welded to the pipe end of another pipe. According to the invention, in a region a wall thickness is created in a first step at the pipe end in question, the thickness being bigger than on the remaining pipe body, wherein the outside diameter is increased and/or the inside diameter is reduced.

  • Patent number: 7797805
    Abstract: A formation and rotation apparatus for use in forming and rotating interconnected sections of a cylindrical workpiece, including a frame and a head arranged within the frame, the head defining two slots and being operatively rotated via an integral drive assembly. A first slide block is slidably disposed within one of the two slots, and a second slide block is disposed within another of the two slots, each of the first and the second slide blocks include a cutting wheel and a beading wheel for successively forming each of the interconnected sections. An armature having an axis of rotation is also provided, along with a gripping mechanism being operatively connected to the armature. A drive mechanism selectively rotates the armature about the axis of rotation after the gripping means has closed about one of the interconnected sections.

  • Publication number: 20100170320
    Abstract: A method for manufacturing a high alloy pipe comprises hot working, a high alloy material pipe having controlled amounts of C, Si, Mn, P, S, Ni, Cr, Mo, Cu, Al, N, O, and optionally Ca, Mg, and rare earth elements, with the balance Fe. The pipe composition satisfies the formula N×O?0.001. The pipe is subjected to cold working to form the high alloy pipe, wherein the final cold working process is performed under the condition that a working ratio Rd in the reduction of area satisfies 15?Rd(%)?370×(C+N), where N, O and C are the contents (by mass percent) of the respective elements, and Rd is the working ratio (%) in the reduction of area. The pipe has an excellent ductility and an excellent corrosion resistance when cold working is performed to obtain a high strength after pipe-making.
