摘要： A high carbon electric resistance welded steel pipe or tube that includes an electric resistance welded part excellent in reliability is provided.
A high carbon steel sheet is used as a raw material steel sheet. The high carbon steel sheet has a composition containing, by mass%, C: 0. 30 to 0.60%, Si: 0. 05 to 0. 50%, Mn: 0. 30 to 2.0%, Al: 0.50% or less, and N: 0.0100% or less. The balance is Fe and incidental impurities. The raw material steel sheet is formed into an approximately cylindrical shape by a cold working. A butt electric resistance welding is performed on the raw material steel sheet to form an electric resistance welded steel pipe or tube. After the butt electric resistance welding, cold-reducing is performed at a reducing rate: 0.8% or less. Immediately after the cold-reducing, reheating is performed or cooling and reheating are performed, and a hot-reducing rolling is performed in a temperature range of 850°C or more at a reducing rate of diameter: 10% or more. These steps as the above form an electric resistance welded part where defects at the electric resistance welded part are restrained and which has excellent reliability. Thus, it is possible to obtain a high carbon electric resistance welded steel pipe or tube whose reliability is remarkably improved. The use of these high carbon electric resistance welded steel pipes or tubes as a raw material also improves reliability in automotive parts.

摘要： A method of fabricating a condenser tube (20) having a pre-determined tube length (L) and multiple channels (22) including the steps of forming an aperture (26) in a flat strip (28) of metal; moving the flat strip (28) through a plurality of forming operations to fold into an enclosed tube containing channels (22), which channels (22) include the aperture (26) in their sides (24) and bottoms (25); and severing (72) the enclosed tube across the aperture to separate the enclosed tube into one condenser tube (20). The aperture (26) eliminates the need for the channel sides (24) to be severed, hence only the portion of the condenser tube (20) enclosing the channels (22) requires severing. Each pair of apertures (26) is spaced from the next pair of apertures (26) by the pre-determined tube length (L) so that each sever produces one condensing tube (20) of the pre-determined tube length (L) with the apertures (26) being divided into open notches (31). The invention also includes a heat exchanger utilizing the condenser tube (20) with channel sides (24) containing portions of the apertures (26).

摘要： The invention relates to a device (1) for production of a tube (2) with a polygonal, preferably rectangular cross-section, comprising a tube welding unit (3), in which the tube (2) is formed from a sheet metal strip and welded at the resulting jointing position and a rolling unit (4), connected to the tube welding unit (3) in the transport direction (R) of the tube (2), which essentially rolls the tube (2) into the desired polygonal cross-sectional contour. According to the invention, right-angled tubes may be produced with the optimal geometry, whereby a camber rolling unit (5) is arranged in series with the rolling unit (4) in the transport direction (R) of the tube (2), by means of which at least two opposing tube sides (6, 7) may be rolled with a pair of crowned convex rollers (8, 9).

摘要： A process for reducing a raw steel pipe obtained by a solid phase bonding pipe manufacturing method or a welding pipe manufacturing method is carried out by heating the steel pipe to a temperature in excess of 100 DEG C and lower than 800 DEG C before it is reduced, restricting the temperature of the steel pipe during a rolling operation to a level in a specific range, controlling the temperature difference of the steel pipe in the circumferential direction thereof at the inlet side of a reducing mill to be in a specific range, and also controlling the temperature of the steel pipe between the stands of the reducing mill. This enables the steel pipe to be reduced with a low load with the work hardening effect minimized without deteriorating the properties of the surface thereof, and the dimensional precision of the product pipe to be maintained at a high level.

摘要： Several pipes (7, 8, 9) which are to be welded or have already been welded are arranged on a table (2). A laser welding device (3, 4, 5, 6) welds the relevant pipe joints. While one pipe is welded it is possible to load the other positions on the table with pipes still to be welded and to unload pipes which have already been welded. This allows for optimal utilisation of the laser welding device.

摘要： The method of forming a seamed metal tube (20c) having a metal coating (56) of this invention includes galvanizing the strip (20) prior to welding. The strip (20) is then formed into an open seam tube (20b) and welded in an inert atmosphere with the seam (71) located in the lower portion of the tube. Finally, the metal coating (56) is caused to flow downwardly over the seam (71), coating the seam (71) by several means. In one embodiment, the strip (20) is preformed into an arcuate shape (20a) and galvanized, wherein the zinc coating (56) increases in thickness toward the lateral strip edges (48), such that the coating (56) will flow over the seam (71) following welding. The tube (20c) may also be reheated following welding, preferably in an enclosure (78) containing an inert atmosphere which includes the weld apparatus (62). In another embodiment, an inert gas is directed over the inner and outer surfaces of the tube (20c), adjacent the seam (71), driving the molten metal downwardly over the seam (71) to coat the seam (71). In another embodiment, the lateral edges (48) of the strip (20) are formed with indentions or grooves (188) directed toward the lateral edges (48) which direct the molten metal downwardly over the seam (71).

摘要： Most existing cutting-off machines on production lines for continuously-processed materials such as steel pipes and profile steel are single-cutter holder synchronous and fixed-length cutting-off machines. Since only one cutter holder provided with a cutter is available, the travelling distance of the cutter holder is small, the time for the cutter to cut off the materials is short, and such cutting-off machine is not suitable for producing short-length products and not suitable for a high-speed production line either. In order to overcome the defects of the prior art, the invention provides a novel method for synchronous and fixed-length cutting-off of continuously-processed materials through multiple cutter holders arranged in series, in particular to a multi-cutter holder series-arrangement synchronous and fixed-length cutting-off machine. The multi-cutter holder series-arrangement synchronous and fixed-length cutting-off machine is provided with two or more cutter holders provided with cutters. The cutter holders are installed on tracks parallel to the materials in a series mode and driven by corresponding driving devices to move back and forth according to a set procedure, and the cutters on the cutter holders cut off the materials according to a set length in the case that the moving speed of the cutter holders becomes the same as that of the materials. The cutting-off machine can be adapted to high-speed production lines, and allow smaller minimum fixed length, longer service life of the cutters, better quality of notches, and smaller number of times of halts for cutter replacement.
