| 20120097732 | CLAD ROLLING MILL FOR JOINING ONE OR MORE PROFILES - A clad-rolling mill adapted to produce a metal tube. The clad-rolling mill includes a first and a second clad-roll arranged to jointly form a nip for clad-rolling. The first and the second clad-rolls are adapted to clad-roll one or more metal profiles arranged to form at least one channel for conduction of a fluid. The first and the second clad-rolls are shaped to clad-roll a first and a second portion of the one or more metal profiles to each other, so that the first and the second portions are joined with each other, wherein the first and the second portions form a seal that holds the one or more metal profiles together. | 04-26-2012 |
| 20120097288 | CLAD ROLLED METAL TUBE - A metal tube including at least one metal profile arranged so that the at least one metal profile forms at least one channel for conduction of a fluid, wherein the at least one metal profile includes a first and a second portion joined with each other by clad-rolling, wherein the clad rolled portions jointly form a clad-rolled seal that holds the at least one metal profile together. | 04-26-2012 |
| 20090263598 | METHOD FOR PRODUCING A METAL TUBE BY CLAD ROLLING ONE MORE PROFILES TO FORM AT LEAST ONE CHANNEL, A CLAD ROLLING MILL FOR JOINING ONE OR MORE PROFILES, A CLAD ROLLED METAL TUBE - A method for producing a metal tube including arranging at least one metal profile to form at least one channel for conduction of a fluid. The at least one metal profiled is fed into a clad-rolling mill. A first and second portion of the at least one metal profile are clad-rolled to each other, so that the first and the second portions are joined with each other. The first and the second portions form a seal that holds the at least one metal profile together and seals at least part of the channel. A clad-rolling mill is adapted to produce a metal tube and a metal tube. | 10-22-2009 |
| 20080251162 | COPPER ALLOY AND METHOD FOR ITS MANUFACTURE - The invention relates to a copper alloy having high recrystallization temperature and good conductivity used in brazed heat exchangers which alloy consists of 0.1 to 0.3% in weight chromium. The invention also relates to a method for the manufacturing of the alloy which method consists of the following steps: casting, cold working, annealing and another cold working before brazing. | 10-16-2008 |
| 20080202653 | Extrusion of a Metal Alloy Containing Copper and Zinc - The invention relates to a method for producing a metal alloy product ( | 08-28-2008 |
